A computed answer — not an opinion. Here's what nearly two decades of honest data say.
There may be something here, but it isn't robust. Don't size into it yet.
We ran rate-of-change momentum through an honest backtest — nearly two decades of survivorship-free NIFTY & BANKNIFTY data, out-of-sample, with real costs. The verdict: 73.3/100 — plausible but fragile. There may be something here, but it isn't robust. Don't size into it yet.
Here's where it breaks:
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.

This verdict was computed on NIFTY 50 and BANKNIFTY index data (survivorship-free) over nearly two decades. It scored 73.3/100 — plausible but fragile.
