Number of signals, trade samples, positive return ratio, average net return, median, best/worst, and comparison across holding periods.
This account does not have full access. Formula details remain visible, while signals, hit history, backtests and matrices from the latest 30 real trading days are hidden. Older data remains available.
No manual backtest record yet; the numbers under "Performance: History / Current / Future" below are automatically generated by the platform daily (consistent methodology).
History
① Run backtest · ② historical win rate · ③ equity curve · ④ track record
Only the author can manually rerun the backtest; the platform automatically updates after market close each day.
This formula has never been backtested — click "Run backtest" above to compute it now (whole market, 1 year, about 20–60 seconds).
No backtest data yet — click "Run Backtest" above to run one.
Statistical Caliber
| Entry / exit | T (signal day) → T+1 entry (default open price, configurable to close price or limit price) → hold for N trading days and sell at close. A-share T+1: cannot sell on the same day of purchase (hold 1 day = sell at next day's close); trade timing: buy at entry day 09:30, sell at exit day 15:00. |
|---|---|
| Costs & slippage | Each trade deducts 0.36% (commission 0.03% both sides + stamp duty 0.1% + slippage 20bp both sides); single trade amount ≤ 1% of daily turnover; forward-adjusted prices; benchmark = SSE Composite Index. |
| NAV basis | Net value accumulated daily based on realized returns (no unrealized gains). |
| Capital tier | Portfolio level = notional — × —% per trade × up to — concurrent positions. |
| Picks per day | Do not confuse the two caps: the listing cap is 20 per day (a user formula above it cannot be listed, but the backtest is unaffected); the backtest truncates at 100 per day (only the first N are taken — that day is not dropped). |
| Risk notice | Historical performance does not guarantee future results and does not constitute investment advice. |
