Functions

clamp01(double v) → double

isF(double? x) → bool

minMax(List<KLineEntity> all, int i, _Pick pick, {int lookback = 50}) → ({double max, double min})

norm01Linear(double v, double lo, double hi) → double

priceAboveToProb(KLineEntity c, double? ref, {double pct = 0.005}) → double

价差归一： (close - ref) / (k * close)，k=0.5%默认
