Community Voices
Real quotes from Reddit comments that inspired this opportunity
- “The painful part is that fixing it properly takes longer than building the strategy in the first place.”
- “Feels like you’ve found something . .. then a small detail kills it. Happens over and over.”
- “I’ve also burned hours and hours on QC trying to avoid lookahead issues, corporate action problems, split/dividend handling surprises”
- “The main risk at this stage is iteration turning into hidden overfitting”
- “Every iteration where you look at a result, adjust something, and rerun, you're burning through a 'backtest budget.'”
- “Big part is realising how easy it is to fool yourself with backtests.”
