After two years out-of-sample test (shadow-trading) of the trading strategy, from August 2023 to August 2025 we can finally share results over a reasonable timeframe, with a severe shock in the market due to global market trade tariffs negotiations, several wars ongoing, etc.
The selected underlyings are NQ=F, ES=F, RTY=F, YM=F, futures on major indexes, extremely liquid, thus they could be related to most of the stock markets trends. No balance of the associated margins, one future each underlying traded and simple trading strategy. Daily predict gain or loss for each underlying and trade long or short accordingly, achieving a natural balance (almost market neutral as they could trade long or short independently every day). Initial margin 53k.

The summary results shows pros and cons and I leave to the reader to interpret results, especially because it is always personal in terms of the acceptable risk and the expected gains.
