The Gold Reaper MT5 analysis
This is the tool I used in the video. Pick the strategies you actually run, and the combined profit curve and drawdown update. Then change the account size and watch what happens to the percentages.
8 strategies · XAUUSD on Axi data · Feb 2020 to Sep 2026 · daily closes · 0.01 lots each
S6About a third of the losses in the engine's worst stress window came from S6. A description, not a recommendation.
Same trades, same lots: the dollars stay the same, the percentages change.
Method & sources
Test conditions
- The Gold Reaper MT5 v4.6, the original version. Version 4.7 only changes the panel.
- Axi XAUUSD data, 1 February 2020 to 26 September 2026, 1 minute OHLC modelling.
- Fixed 0.01 lots per strategy. Not Auto mode.
- Commission 0.
- Drawdown measured at the daily close, as a percentage of the initial account.
How your mix is calculated
For the strategies you select, the daily profit and loss is added up day by day and accumulated from your account size. The peak and the drawdown are then recalculated for the combined curve. Individual drawdowns are never added together.
Each strategy keeps its 0.01 lots, so adding a strategy adds exposure. The eight histories were exported separately and combined here: margin and execution interactions are not re-simulated. 2,425 daily closes.
Stress test
1,000 scenarios rebuilt from the same history: 10-day blocks, synchronised across the eight strategies, 10% of trades left out and results scaled between ×0.85 and ×1.15. The 95th percentile drawdown is $574, which is 14.3% of $4,000. With fixed lots that dollar figure doesn't change when you change the account size, the percentage does.
It was only run for all eight strategies. For a partial mix there's no figure, so the tool doesn't show one.
About S6
In the engine's worst stress window, S6 accounted for 35.2% of the losses. That describes that window. It's not a recommendation to switch S6 off: removing it also removes its profit, and you can see both in the tool.

- Public signal linked from that page, checked 27 September 2026. It runs on a different broker and its description lists an older version, so it isn't the same setup as this test.

Your own portfolio
If you run more than one EA, the question is the same: what does the combination do on the bad days? DoIt Portfolio Lab does that with your own MT5 backtests.
