9 Sessions That Killed My Trading Bot — A Quant Developer's Forensic Case Study

After months building a Walk-Forward + Genetic Algorithm systemwith backtest Sharpes of 1.1 to 2.74, I sat down with nineacademic papers and asked: "Is any of this real?"The answer was no.This is the complete forensic record — backed by peer-reviewedliterature — covering:→ The 3 structural risks every WFA-GA engine carries→ Why DSR calculations revealed my Sharpes were functionally zero(Bailey & López de Prado, 2014; Harvey et al., 2016)→ Why I couldn't even prove the problem rigorously(the trial logs were auto-deleted)→ The decision framework when every option has a fatal flaw→ A pre-trade validation checklist with DSR/PBO/WFE metricsWHO THIS IS FOR:→ Algo traders running optimisation-based backtesting pipelines→ Quant developers who want to know if their backtest is real→ Anyone whose "excellent" backtest fails liveWHO THIS IS NOT FOR:→ People looking for a trading strategy to copy→ Beginners with no backtesting experienceThis is not a trading system. It is a rigorous, honestanalysis backed by peer-reviewed research — written bysomeone who built the system, ran it live, lost money,and documented exactly why.
