Multi-Coin Scanner
Runs one strategy across many coins with a walk-forward split: the in-sample segment is where an edge would have been discovered, the out-of-sample segment is scored blind. Results are ranked by OOS Sharpe and summarized by how many coins stay profitable — a formula that only works on one cherry-picked chart is noise. Note the coin list itself is today's survivors, so historical results carry survivorship bias.
Signals are computed once per coin over the full window and sliced at the split date; the OOS simulation starts flat with full warmup history, exactly like an account funded on that day.
Scan the RSI 30/70 strategy across every coin
Mean-reversion edges are notoriously local: buying oversold conditions prints money on some coins and loses steadily on others. This scan runs the RSI 30/70 rule — long when RSI(14) recovers above 30, out when it drops below 70 — across the whole universe and splits each coin's history walk-forward.
The out-of-sample columns show how the rule performed on data it was never tuned on, and the summary counts how many coins stayed profitable after the split. If the oversold-buy edge is real in the current regime, it survives broadly; if it only shows in-sample, the OOS ranking exposes that immediately.
How it works
- Pick an interval, the coin universe (majors or all) and the walk-forward split.
- The strategy formula loads into the editor, fully editable.
- Set fees and slippage, then scan — every coin is backtested with the same rules.
- Rank by out-of-sample Sharpe, return, drawdown or win rate.
Frequently asked questions
How are coins ranked in the RSI 30/70 scan?
By default, by out-of-sample Sharpe — annualized risk-adjusted return on the held-out segment only. Every column can be sorted, including OOS return, max drawdown, win rate and outperformance versus buy & hold.
Why does the same RSI strategy win on some coins and lose on others?
Mean reversion needs ranging or recovering price action; coins in relentless downtrends keep RSI depressed and the strategy keeps catching knives. The scan's per-coin OOS results are precisely the tool for spotting which regime each coin is in.
