Quick Start: OHLC Indicators

You can quickly create OHLC-based indicators (such as ATR, ADX) using NewOHLCIndicator:

atr, err := indicator.NewOHLCIndicator("ATR", 14)
adx, err := indicator.NewOHLCIndicator("ADX", 14)
if err != nil {
    panic(err)
}
for _, candle := range candles {
    atr.UpdateOHLC(candle.Open, candle.High, candle.Low, candle.Close)
    adx.UpdateOHLC(candle.Open, candle.High, candle.Low, candle.Close)
}
fmt.Println("ATR:", atr.Result())
fmt.Println("ADX:", adx.Result())
fmt.Println("+DI:", adx.PlusDI(), "-DI:", adx.MinusDI())

Currently supported: ATR, ADX. More OHLC indicators can be added easily.

Note:

• For accurate results, always use UpdateOHLC(open, high, low, close).
• wilderAverage is the internal smoothing engine for ATR/ADX:
  • Warm-up: uses SMA to initialize the first smoothed value
  • Running: next = (prev*(period-1) + current) / period
• During warm-up, ATR/ADX may return 0 until enough data arrives.
• Both indicators also support the simple Update(price) interface (close-only fallback).
