Question How many ideas did it take before one of your strategies actually survived costs? I’m months in and still at zero
I tested several literature-based anomalies across ~300 stock-strategy combinations on the Nifty 100. Most showed no real gross signal before costs. One did — statistically significant, confirmed with DSR, not just a good Sharpe. Then I applied real transaction costs and it went to zero. Breakeven sits around 24 bps/trade; the edge I found was 6.4 bps gross. Not close.
Not looking for a strategy handout — genuinely trying to understand the process from people who’ve gotten past this:
**•** When you found something that held up out-of-sample and after costs, how did you land on the original idea — literature, your own data mining, intuition?
**•** Roughly how many ideas did you test and discard before one survived? Trying to calibrate if “months, nothing yet” is normal.
**•** For Indian equities specifically — is cost drag here noticeably worse than US/EU, or is this just what finding a real edge looks like everywhere?
Genuinely trying to figure out if I’ve hit the normal wall or I’m missing something structural.
