Real quotes from Reddit comments that inspired this opportunity
- “Backtest looked clean but live execution had slippage I didn't account for, especially around news.”
- “Spread widening alone killed a few setups that would've closed green on paper.”
- “A lot of first systems don’t die because the idea is terrible, they die because the backtest was kinder than the market.”
