price_distance is true when the current close is within a percent
threshold of the named indicator. Both directions count - above or
below, as long as the absolute distance is small enough.

{ "type": "price_distance", "from": "ema_fast", "max_pct": 5.0 }Params
from- indicator column to measure distance from.- max percent - maximum distance as a percent of the indicator value.
Usage
- Pullback entries: long after a trend-detection bullish flip,
but only if price is still close to the trend EMA (
max_pct: 5). Prevents entering on a stretched run-away. - Mean-reversion: pair with an oversold condition to filter for setups near a support reference.
Pitfalls
- % choice is symbol-dependent. 5% from EMA20 on BTC is a normal pullback; 5% on ES is multiple ATRs.
- Volatility regimes change the right threshold. Consider basing it on ATR via comparison instead for adaptive setups.
