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 Trend Dip strategy across every coin
Trend Dip only works where an uptrend exists, so the cross-section is the honest test: this scan runs the rule — buy the close that reclaims the lower Bollinger band while price holds above MA100, sell at the mid band — across the whole coin universe with each coin split walk-forward into in-sample and held-out segments.
In a 40-coin, 4-hour study the strategy stayed profitable on roughly two thirds of coins out of sample and won at least 50% of its trades on 33 of the 35 coins with three or more held-out trades — the kind of breadth that distinguishes a market behavior from a lucky chart. The ranking defaults to out-of-sample Sharpe; sort by win rate or outperformance to see the profile from other angles.
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
What does a "long" position in the scan table mean?
It means that coin's latest closed bar still satisfies the strategy's hold condition — it entered on a lower-band reclaim above MA100 and has not yet closed back at the mid band. It is a snapshot of the rule's current stance, not trading advice.
How do I tune the trend filter or the bands in the scan?
TREND and MULT are editable parameters (TREND:=100; MULT:=2; lines in the formula). The rule stayed profitable across 1.8σ–2.5σ bands and 50–200-bar trend filters in testing, so the defaults sit in the middle of a plateau, not on a tuned spike — rescan with your own values to check.
