A computed answer — not an opinion. Here's what nearly two decades of honest data say.
Clears all five traps that fool most backtests — necessary, but not sufficient. This does NOT promise future profit; no backtest can. Verify with paper/live before risking capital.
Across nearly two decades of survivorship-free NIFTY & BANKNIFTY data — out-of-sample, after real costs — the stochastic oversold signal scored 81.3/100 and actually survives honest scrutiny. That's rare: most strategies people teach fall apart under this kind of test.
Here's what it gets right:
Five statistical tests, no mercy: out-of-sample decay (is the edge curve-fit?), Monte-Carlo robustness (is it just luck?), real cost & slippage survival, survivorship-bias exposure, and sample-size adequacy. Run on NIFTY 50 and BANKNIFTY — survivorship-free by construction, the most honest data available — across roughly two decades. Rules are read at each day's close and filled the next open, so the strategy can never peek at the bar it trades on.

Test the stochastic oversold signal yourself →On a true, survivorship-free test (81.3/100, survives scrutiny), the stochastic oversold signal holds up. A backtest looking profitable is not the same as a strategy being real — most aren't. Test your own version free at The Honest Quant.
This verdict was computed on NIFTY 50 and BANKNIFTY index data (survivorship-free) over nearly two decades. It scored 81.3/100 — survives scrutiny.
