ROC (10): what it's actually best at
ROC (10) is a momentum rule — it holds while rate-of-change stays positive and steps aside when it rolls over. We publish where it holds up and where it fails, with the out-of-sample numbers; the exact settings we tested stay in the engine.

How often ROC (10) beat buy-and-hold
372 of 1,846 out-of-sample tests beat simply buying and holding the same asset — 20.2%. On the other 1,474 it did not. That is indistinguishable from the 20.1% rate across all 382 indicators we test (one pooled rate over all 660,005 tests we have run, not a mean of the per-indicator rates) — the difference is inside the margin this many tests can resolve, so read it as ordinary, not better or worse.
Each test is one asset on one timeframe: 1,846 of them, drawn from 900 assets across up to 4 timeframes. Not every asset has usable history on every timeframe, so that total is the grid we could actually run — it is not 900 × 4, and we do not pad it with tests we did not do. "Beat" means a higher return than holding that same asset over that same window. Measured out-of-sample — on data the setup was not chosen on.
Picking the single best timeframe for each asset after the fact raises it to 27.6% (248/900 assets). That number is the one worth distrusting: choosing the timeframe once you already know the answer is how backtests flatter themselves. Every indicator, ranked by this number
We publish the verdict: the indicator's name, the assets and timeframes it holds up on, and the honest numbers for both its wins and its failures. We do not publish the recipe — the settings, lengths and thresholds we tested. That is the part worth paying for, and republishing it would just add one more free indicator to a market that already has thousands. Everything you need to judge whether ROC (10) is worth your attention is below; everything you'd need to clone it is not.
In our standard-settings test, ROC (10) wasn’t the single best indicator for any asset — it was outperformed by others on every one. That’s useful to know too: no indicator wins everywhere.
