Stats

A news scan found the text of a report from an automated trading fund manager. The report discusses the performance of a trading strategy, called Premise1, which uses a 20-day high and 10-day low, with a 14-day average true range, or ATR, for risk management, and a net target of 3R, with a 25 basis point credited asset fee and a 10 basis point slip. The strategy has a 20-day timeout and a signal is known after a completed bar, with the next exact open. The report also mentions a cost basis, or BE, of +2R and a peak entry ATR trail, with a retained target. A 20 basis point slip stress leaves the target fixed. The report uses a native calendar-hourly timeframe, with 20 completed UTC days, and a rolling-hourly prior 480 hours. The report is based on two premises, or assumptions, with the first being a chronological train from 2024 to 2025, and a reused holdout from 2026 January 1 to September 11, at 00 UTC, with a reset to flat. The report also discusses the performance of the strategy, with a 41.228668% return on the full native calendar-hourly train, and a 7.324178% return on the holdout, with a 42.857143% win rate and a 19.830197% drawdown. The report also mentions a same-target stress test, with a 5.832105% return. The report breaks down the attribution of the strategy, with a full native calendar-hourly train, and a daily and hourly open sampled exit, with no guarantee of stop price. The report also mentions a raw wealth reconciliation, using a vectorbt 1e-10. The report concludes that the validity of the results is due to controlled changes, and that the soundness of the results is limited by tiny reused samples, historical bar anomalies, and sampled quotes. The report is based on 80 cells per asset, with 168 matched and 72 full native, for a total of 240, but notes that these are not 80 independent trials. The source of the data is https://runway.adityaperswal.workers.dev/data/crypto-bars, and the method notes are 2175/2180.

A news scan found the text describing an automated trading fund manager's notes. The notes discuss a trading strategy for Bitcoin (BTC) with specific rules. The strategy has a 20-day high and 10-day low premise, with a 14-day average true range (ATR) risk, which is a measure of price volatility. The target return is 3 times the risk, with a 25 basis point (0.25%) asset fee and a 10 basis point (0.10%) slip, which is the difference between the expected and actual price. The strategy also has a 20-day timeout. The signal to buy or sell is known after the bar is completed, and the next exact open price is used. The strategy also includes a 2 times risk cost and a peak minus 2 times ATR trail, which is a way to adjust the stop-loss price. The notes also discuss the training and testing of the strategy using historical data from 2024-25 and 2026. The results show a return of 30.44% for the training period and 2.08% for the testing period, with a win rate of 42.86%. The notes also discuss the attribution of the returns to different factors, including the native calendar-hourly and daily returns. The conclusion is to watch the strategy, but not to switch to it based on the results. The validity of the results is limited by the small sample size and historical bar anomalies. The source of the data is https://runway.adityaperswal.workers.dev/data/crypto-bars, and the method notes are numbered 2175/2180.

A preregistered note, number 2178, outlines a trading strategy for KALU, which involves closing above the prior 20-day close high and SMA50, with a next session open entry, stop at 2 times the prior 20-day average daily range, and a target of 6 times the average daily range, with a 3R ratio, and exiting on the 20th session close. The strategy was trained on data from 2020 to 2024 and tested on a holdout period from 2025 to September 10, 2026. The data source is from https://runway.adityaperswal.workers.dev/data/stock-bars?feed=sip&adjustment=all. The results show a return of -14.05% during the training period, with a drawdown of 55.15%, and a return of 47.76% during the holdout period, with a drawdown of 28.95%. The stress test return was 42.82%. A four-trade circular block bootstrap test with 10,000 samples showed that the mean confidence interval crosses zero. The conclusion is that the positive holdout results alone cannot fix the negative compounded training results or support retrospective sizing, and therefore, it is a research watch only, with no current signal and no defensible new allocation.

A preregistered note, number 2178, outlined a trading strategy for the CSTM stock, which is a type of aluminum-chain benchmark. The strategy was to buy the stock if its price closed above the highest price of the previous 20 days and the 50-day moving average, and then sell it when it reached a target price or after 20 days. The strategy was tested using data from 2020 to 2024, and then its performance was evaluated using data from 2025 to September 10, 2026. The results showed that the strategy had a return of -38.61% during the training period and 31.78% during the holdout period. The holdout period is a time when the strategy is tested on new data to see how well it performs. The stress test return was 27.89%. The results also showed that the strategy had a high drawdown, which is the largest decline in value from a peak to a trough, of 47.12% during the training period and 19.56% during the holdout period. A drawdown is a measure of risk. The strategy was also tested using a bootstrap method, which is a statistical technique, and the results showed that the mean confidence interval crossed zero. The conclusion is that the strategy is only for research purposes and does not currently have a signal to buy or sell the stock, and the positive results during the holdout period are not enough to make up for the negative results during the training period.

A news scan found the headline about a pre-earnings stock proxy for BB that failed training despite a positive holdout. The edge test was frozen on September 11, with the stock price at $7.54 for BB. The test looked at two scenarios: one where the stock price would need to increase by 11.405836% to reach $0.40 by October 2, and another where the stock price would need to decrease by 11.405836% to reach $0.32 by October 2. The test covered 3 out of 12 periods, or 25%, in the first scenario, and 2 out of 12 periods, or 16.67%, in the second scenario. The test looked at 12 consecutive quarterly releases from September 2023 to June 2026, and found that the median absolute change in stock price from before to after the earnings release was 9.987505%. The test also found that neither a 40% gate nor a documented 3x expected option payout passed. The option expiry date was October 2, which is 8 days after the September 24 event. The default exit date was September 23, but the hurdle exceeded the median by 1.418331 percentage points, so there was no hold-through exception. The sources for this information include issuer-dated event observations 24113-24126, and data from https://investors.blackberry.com/ and https://runway.adityaperswal.workers.dev/data/stock-bars and /data/option-bars. The test used a vectorbt system with T-3/T-5/T-10 open entries and T-1 close exits, with 5 basis point fees plus 10 basis point slippage on each side. The test also raised slippage to 30 basis points to stress the system. The full $100 stock allocation is a diagnostic, and is outside the fund's instrument mandate. The test found that the training returns were -10.3639%, -2.73664%, and -20.6952% respectively, and selected the T-5 option by training return only. The selected holdout return was +2.23248%, with a daily drawdown of 9.40210% and 2 wins out of 4. The stress train return was -5.79981%, with a holdout return of +0.609767% and a drawdown of 9.76377%. The unselected T-10 holdout return was +23.2792%, but this cannot replace the negative training return. A separate required CLI momentum diagnostic found a return of +261.0066%, with a drawdown of 36.1282% and a win rate of 40.7407%, but this did not include a chronological holdout, so it was not adopted. The validity of the test is that an unsplit momentum winner cannot establish an earnings option edge, and the soundness of the test is that a daily time-only stock proxy omits option theta, volatility crush, spreads, and mandated option stops/targets/15-minute checks. All training losses plus failed event coverage leave the size at zero.

A diagnostic test for BFRI911 was run using a momentum strategy with specific parameters, including a 20-day lookback period, 1460 days of data, a 5% stop loss, and a 15% target profit. The test used 1003 daily price bars from IEX and resulted in 124 closed trades. However, the raw prices showed a discontinuity due to a July 2023 split, which made them not comparable with the 1176 SIP adjustment used in the study. A full sample diagnostic was performed without a costed holdout, but it was not an event study and was not adopted. Additionally, an independent fixed rule long-only test with a costed chronological holdout from 2477 to 2480 also failed. The data source was https://runway.adityaperswal.workers.dev/data/stock-bars?feed=iex and local cli.json.

A frozen note, number 2174, outlines the premises of a test. The test uses nine sector ETFs, with daily bars adjusted for dividends and splits, from January 4, 2021, at 05:00:00+00:00 to September 10, 2026, at 04:00:00+00:00. The test buys the worst-performing sector from the previous five sessions if it is negative, using the previous close as a signal to fill at the next open, with one cash-only fractional sleeve. The test uses a stop loss based on the average true range, or ATR, which is a measure of volatility, set at 20 periods and 1 times the range, with a target of 3 times the range and a 2 times the range quarter, and a breakeven point the following day. The test also uses gap open and conservative barriers, with a weekly time exit. The test only enters a trade if the prior 20-day realized volatility of the SPY, which is a measure of how much the price of the SPY has fluctuated, is greater than 20%, but not based on the VIX, which is a measure of expected volatility. The fees for the test are 1 basis point, or 0.01%, plus 15 basis points, or 0.15%, for slippage on each side. The test has four phases per day, using a vectorized backtesting approach, with long-only positions and cash sharing, reconciled every day, with no hidden leverage. The mean trade confidence interval, which is a measure of the range of possible values, is between -1.202347268207001% and 0.9499598378533135% at a 95% confidence level, based on 5000 bootstrap samples clustered by month. The reasons for trade exits are: 19 times due to time, 17 times due to stop loss, 3 times due to gap stop, and 2 times due to target, with 3 partial exits and 3 same-day final exits. The current incomplete week is excluded, and all observations and source data are archived. An audit of opening partials before intraday stops did not change any cells. The conclusion of the test is that the primary strategy fails to be robust to costs, and controls cannot replace the primary strategy after holdout inspection. The mechanics of adjusted dividends, 15-minute monitor fills, fractional to whole-share partial exits, slippage estimates, and pattern day trader rules remain unvalidated.

The strategy involves nine sector ETFs, with daily bars adjusted for splits and dividends, from January 4, 2016, to December 31, 2020. Each week, the strategy buys the sector with the worst return over the prior five sessions, but only if that return is negative. The buy is executed at the next open, with a signal from the prior close, and is a cash-only, fractional sleeve. The strategy uses a stop loss based on the average true range over 20 days, with a target of three times the risk and a barrier of two times the risk, and exits at the end of the week or when the target is reached. The strategy also considers the realized volatility of the SPY over the prior 20 days, but not the VIX. Fees are one basis point plus 15 basis points for slippage on each side. The strategy has four phases per day and is reconciled daily. The mean trade confidence interval is between -0.7943843415420596% and 0.8182585213220581% over 5000 bootstrap samples. The reasons for trades are: stop losses 19 times, time exits 23 times, and target reaches 1 time. There are 2 partial exits and 7 same-day final exits. The current incomplete week is excluded from the analysis, and all observations and source data are archived. An audit of the opening partial before intraday stop did not change any results.

Each week, the strategy buys the sector with the worst return over the prior 10 sessions, but only if that return is negative. The buy order is filled at the next open, with a signal from the prior close, and is a cash-only, fractional sleeve, meaning it can buy a fraction of a share. The strategy uses a stop-loss, which is a price level at which to sell a security, set at 1 times the average true range, or ATR, over 20 sessions, and a target price set at 3 times the ATR, with an additional 2 times the ATR as a quarterly target, and a breakeven point the following day. The strategy also includes gap open, conservative barriers, and a weekly time exit, meaning it will sell at the end of the week. There are fees of 1 basis point, plus slippage of 15 basis points on each side of the trade. The strategy has four phases per day, uses vectorized backtesting, and is long-only, meaning it only buys securities, with cash sharing reconciled daily. The strategy does not use hidden leverage, meaning it does not use borrowed money to buy more securities. The mean trade confidence interval, a measure of the strategy's performance, is between -0.3248899491009365 and 0.09155388045638681 percent, based on 5000 bootstrap samples, which is a statistical method.

A frozen note, number 2174, was reviewed. The test was based on 9 sector ETFs, with daily price changes adjusted for dividends and splits, from January 4, 2021, to September 10, 2026. The test bought the worst performing sector from the previous 10 sessions, but only if it had a negative return, and sold at the next open. The test used a stop loss, which is a price level at which to automatically sell a security, set at 1 times the average true range, or ATR, over 20 days, and a target price set at 3 times the ATR. The test also used a barrier, which is a price level that triggers a sale, set at 2 times the ATR above the target, and exited positions at the end of each week. There were fees of 1 basis point, or 0.01%, plus slippage, which is the difference between the expected and actual price of a trade, of 5 basis points, on both the buy and sell sides. The test was run in four phases per day, using a vectorized backtesting framework, and was long only, meaning it only bought securities, and used cash sharing, which is a method of allocating cash to different securities. The test was reconciled daily, and there was no hidden leverage, which is borrowing to invest. The average trade return was between -0.12% and 0.50% with 95% confidence. The test had 41 partial exits, which are sales of part of a position, and 23 same-day final exits. The current incomplete week was excluded from the test, and all observations and source data were archived. An audit of the opening partial before intraday stop did not change any results. The conclusion of the test was that the primary strategy failed to be robust, and the controls, which are tests used for comparison, could not replace the primary strategy after inspection. The test did not validate dividend mechanics, 15-minute monitor fills, fractional to whole-share partial exits, slippage estimates, and pattern day trader, or PDT, rules.

A news scan found the note about the REV9110400 neighbor3_15_test, which costed a weekly reversal. The note starts with the premises that it uses nine sector ETFs and daily bars that are all-adjusted for SIP, from January 4, 2021, at 05:00:00+00:00 to September 10, 2026, at 04:00:00+00:00. The first session of each week buys the sector with the worst return over the prior three sessions, but only if that return is negative. It uses a signal from the prior close to fill at the next open, and it only uses cash, with fractional shares allowed in one sleeve. The note mentions an ATR20 stop, which is a stop-loss order based on the average true range over 20 periods, and a target of 3R, which means three times the risk, with a 2R quarter, which is two times the risk for a quarter of the trade, and a break-even point the following day. It also mentions a gap open, conservative barriers, and a weekly time exit, which means the trade is closed at the end of the week. The fees are 1 basis point plus 15 basis points for slippage on each side, which means the difference between the expected price and the actual price. The note also mentions four phases per day, vectorbt long-only cash sharing reconciled every day, and no hidden leverage, which means borrowing money to invest. The mean trade confidence interval at 95% is between -0.41598039756013533% and 0.1716584000385664%, which is a measure of the uncertainty of the trade returns, based on 5000 bootstrap samples, which is a statistical method to estimate the variability of the returns. The reasons for the trades are given as a dictionary with keys for stop, gap stop, time, target, and gap target, with values 118, 15, 120, 7, and 1, respectively. The note also mentions partials, which are 34, and same-day final exits, which are also 34. The current incomplete week is excluded, and all observations and source data are archived. An audit of the opening partial before the intraday stop did not change any cell. The conclusion is that the primary strategy fails the cost robustness test, and the controls cannot replace the primary strategy after holdout inspection. The note also mentions that adjusted dividend mechanics, actual 15-minute monitor fills, fractional to whole-share partial exits, slippage estimates, and PDT, which is a pattern day trader rule, remain unvalidated.

A news scan found the note: Frozen note2174. The premises of this test are based on 9 sector ETFs, with all-adjusted daily bars from 2021-01-04 05:00:00+00:00 through 2026-09-10 04:00:00+00:00. The strategy buys the worst-performing sector from the previous 3 sessions if it is negative, using the prior close as a signal to fill the next open, with one cash-only fractional sleeve. The strategy uses a 20-day average true range, or ATR, which is a measure of volatility, as a stop loss, with a target of 3 times the risk, or R, and a 2R quarter, and a break-even point, or BE, the following day. It also uses a gap open, conservative barriers, and a weekly time exit. The fees are 1 basis point, or bp, plus 5bp for slippage, which is the difference between the expected and actual price of a trade, on each side. The strategy is reconciled every day, with four phases per day, using a vectorbt, which is a backtesting framework, long-only, cash-sharing approach, with no hidden leverage, which is the use of borrowed money to increase potential returns. The mean trade confidence interval, or CI, is between -0.2562198984201958% and 0.33990779442520025%, with a month cluster of 5000 bootstrap, which is a statistical method. The reasons for the trades are: 114 stops, 14 gap stops, 125 time exits, 7 targets, and 1 gap target. There were 36 partial trades and 32 same-day final exits. The current incomplete week is excluded, and all observations and source data are archived. An audit of the opening partial before intraday stop did not change any cell. The conclusion of this research is that the primary strategy fails to be robust, and the controls cannot replace the primary strategy after holdout inspection, which is a method of testing a strategy. The mechanics of adjusted dividends, 15-minute monitor fills, fractional to whole-share partial exits, slippage estimates, and pattern day trader, or PDT, rules remain unvalidated.

A frozen note, number 2174, outlines the premises of a trading strategy. The strategy involves nine sector ETFs, with daily price adjustments, from January 4, 2016, to December 31, 2020. Each week, the strategy buys the sector that performed the worst over the previous three sessions, but only if it had a negative return. The purchase is made at the next open price, with a signal from the previous close. The strategy uses a cash-only approach, with fractional shares allowed. A stop-loss is set at one times the average true range over 20 days, with a target of three times the range and an additional two times the range as a quarterly benchmark. The strategy also includes a gap open and conservative barriers, with a weekly time exit. Fees are one basis point plus slippage of five basis points on each side. The strategy has four phases per day, with vector-based backtesting and long-only cash sharing, reconciled daily. There is no hidden leverage. The mean trade confidence interval is between -0.0623% and 0.5203%, based on 5000 bootstrap samples. The reasons for trade exits are: gap stop 14 times, time exit 117 times, stop loss 84 times, target reached 5 times, and gap target 4 times. There were 30 partial exits and 28 same-day final exits. The current incomplete week is excluded from the analysis, and all observations and source data are archived. An audit of opening partials before intraday stops did not change any results. The conclusion is that the primary strategy fails to provide cost robustness, and controls cannot replace the primary strategy after inspection. Adjusted dividend mechanics, 15-minute monitor fills, fractional to whole-share partial exits, slippage estimates, and pattern day trader rules remain unvalidated.

A frozen note, number 2174, outlines the premises of a test. The test uses nine sector ETFs, which are a type of investment fund that tracks a specific sector, and uses daily bars, which are a type of data that shows the high, low, open, and close prices of a security over a given period, that have been adjusted for splits and dividends. The test ran from January 4, 2021, at 5:00:00 UTC, through September 10, 2026, at 4:00:00 UTC. The test buys the sector with the worst return over the prior five sessions, but only if that return is negative, and it does so at the next open, filling the order at the prior close price, using a cash-only approach that allows for fractional, or partial, shares. The test also has a time-only weekly exit control, which means that positions are closed based on time, not on price movements. The test includes fees of 1 basis point, which is a unit of measurement for interest rates and fees, plus slippage of 15 basis points on each side of the trade, which means that the test accounts for the difference between the expected price of a trade and the actual price. The test uses a vectorbt, which is a type of backtesting framework, long-only approach, which means that it only buys securities, and it reconciles, or matches, the daily equity, which is the total value of the portfolio, every day. The test also uses a cash-sharing approach, which means that it allocates cash to different parts of the portfolio. The mean trade confidence interval, which is a statistical measure of the range of possible values for a trade, is between -0.42498062146571663% and 0.2751204592455909% at a 95% confidence level, which is a statistical measure of the reliability of the results, based on 5000 bootstrap samples, which is a type of statistical simulation. The reasons for the test include a time value of 255, and the test had no partial exits, which are exits from a position that are not complete, and no same-day final exits, which are exits from a position that occur on the same day as the entry. The current incomplete week was excluded from the test, and all observations and source data were archived, and an audit of the opening partial before intraday stop, which is a type of risk management strategy, did not change any of the results. The conclusion of the test is that the primary strategy fails to meet the cost robustness, which means that it is not profitable after accounting for costs, and that the controls, which are the parts of the test that are designed to manage risk, cannot replace the primary strategy after holdout inspection, which is a type of statistical analysis. The test also notes that several mechanics, including adjusted dividend mechanics, actual 15-minute monitor fills, fractional to whole-share partial exits, slippage estimates, and PDT, which is a type of regulatory rule, remain unvalidated, which means that they have not been tested or proven. The source of the data for the test is https://runway.adityaperswal.workers.dev/data/stock-bars, and this adaptation is not related to Nagel's 48 industry daily short portfolio, which is a type of investment strategy.

The strategy buys the sector with the worst return over the prior five sessions if it is negative, using the prior close as a signal to fill the next open, and only uses cash, with fractional shares allowed. The strategy exits at the end of each week, based on time only. The fees are one basis point, which is a unit of measurement for interest rates and fees, plus 15 basis points for slippage, which is the difference between the expected price and the actual price, on each side of the trade. The strategy uses a vectorized backtesting framework, which is a way of testing a strategy using historical data, with four phases per day, and is reconciled daily. The mean trade confidence interval, which is a statistical measure of the range of possible values, is between -0.46% and 0.14% at a 95% confidence level, based on 5000 bootstrap samples, which is a statistical method for estimating the variability of a sample. The reasons for the strategy include a time parameter of 220. The strategy does not use partial fills or same-day final exits. The current incomplete week is excluded from the analysis, and all observations and source data are archived. An audit of the opening partial before intraday stop did not change any cells. The conclusion is that the primary strategy fails to be robust, and the controls cannot replace the primary strategy after inspecting the holdout data, which is a portion of the data set aside for testing. The mechanics of adjusted dividends, 15-minute monitor fills, fractional to whole-share partial exits, slippage estimates, and pattern day trader rules remain unvalidated.

The reasons for the strategy include a time factor, with 220 time periods considered. The strategy excludes the current incomplete week and archives all observations and sources. An audit of the opening partial and intraday stop did not change any results. The conclusion is that the primary strategy fails to be robust, and controls cannot replace the primary strategy after inspection. The strategy still needs to validate its mechanics, including adjusted dividend handling, 15-minute monitoring, and slippage estimates.

A frozen note, number 2174, outlines the premises of a test. The test uses nine sector ETFs, with daily bars that are adjusted for dividends and splits, from January 4, 2021, at 05:00:00+00:00 to September 10, 2026, at 04:00:00+00:00. The first session of each week buys the sector that had the worst return over the prior five sessions, but only if that return was negative. The purchase is made at the next open, with a signal from the prior close, and is a cash-only transaction that allows for fractional shares. A stop loss is set at one times the average true range over 20 days, with a target of three times that range, and an additional two times that range for a quarter, and a breakeven point the following day. The test also includes a gap open, conservative barriers, and a weekly time exit. Fees are one basis point plus 15 basis points for slippage on each side of the trade. The test has four phases per day, using a vectorized backtesting approach, and is long-only, with cash sharing reconciled daily, and no hidden leverage. The mean trade confidence interval at 95% is between -0.31652818404002264% and 0.2633172689313565%, based on 5000 bootstrap samples clustered by month. The reasons for certain decisions are given, with a gap target of 1, a stop of 106, a time of 123, a gap stop of 17, and a target of 8. There were 35 partial trades and 30 same-day final exits. The current incomplete week is excluded from the test, and all observations and source data are archived. An audit of the opening partial before the intraday stop did not change any results. The conclusion of the test is that the primary strategy fails the cost robustness test, and controls cannot replace the primary strategy after inspecting the holdout data.

Each week, the strategy buys the sector with the worst return over the previous five sessions, but only if that return is negative. The buy signal is based on the prior day's close and the next day's open, with a cash-only fractionalsleeve, which means a portion of the investment is in cash. The strategy uses a stop-loss, or a price level at which to automatically sell, based on the average true range, or ATR, a measure of price volatility, over 20 days, with a target of three times the risk, or R, and a barrier, or price level, two times the R above the target. The strategy also has a weekly time exit, meaning it sells at the end of each week. There are fees of one basis point, or 1bp, plus slippage, or the difference between the expected and actual trade price, of 15bp on each side of the trade. The strategy has four phases per day and uses a vectorbt, a type of backtesting framework, for long-only, or buy-only, trades, with cash sharing reconciled every day. The strategy does not use hidden leverage, or borrowing to increase investment. The mean trade confidence interval, or CI, is between -0.45947011023146633 and 0.0412389443528169 percent, based on 5000 bootstrap samples, which are random samples of the data. The reasons for trades are: stop-loss 102 times, time exit 101 times, gap stop, or a stop-loss based on a large price gap, 11 times, and target 6 times. There were 22 partial trades and 32 same-day final exits. The current incomplete week is excluded from the analysis, and all observations and source data are archived.
