价格比率过滤器 is a pass/block filter on closeA ÷ closeB. It never fires buy or sell alone.
Prefer 价格比率 when the ratio itself should emit a side.
When to use
- Only enter while relative strength vs a reference holds
- Block when the ratio collapses
What you’ll set
Add 价格比率过滤器 under filters: Symbol B (required), Mode (原始（A÷B） / 比率 Z 分数), Window, Compare, Threshold.
Example
Entry filters: 价格比率过滤器, EWZUSDT, 原始（A÷B）, ratio > 0.15 — a long RSI on USDBRLUSDT only passes while the ratio stays elevated.
