No slides and no mockups. This is a Python engine streaming a bar-by-bar replay into a terminal I built, captured off my screen while it ran.

The system: SMAx(7,8) AND MACD(16,40,13) AND Chand(50,1.5) must all agree. Long when all three read up, short when all three read down, always in the market, 0.30 per flip in costs.

Before it streams a single candle the engine re-derives every indicator from the raw series and asserts it is identical, bar for bar, to the column my 2.45 billion system sweep scored. All three passed on all 21,936 bars. You can see that check run in the engine log.

The trade shown in slow motion is real: long XAUUSD at 5176.42 on 2026-01-27 20: 00 UTC, out at 5510.42 thirty nine candles later, +333.70.

Final: 968 trades, 39.8% winners, net 5,181.30, profit factor 1.54, max drawdown 465. Gold 1H, OANDA feed via TradingView, 2023-01-02 to 2026-09-16.

A 39.8% win rate that still makes money is the whole point: the winners are bigger than the losers. Next video is the Monte Carlo that decides how much of this is skill and how much is luck.
