import detector from "currency-pattern-detector/build";

interface ICandle {
  open: number;
  close: number;
  high: number;
  low: number;
}

const candles: ICandle[] = [
  { open: 45.0, high: 46.2, close: 41.2, low: 38.56 },
  { open: 33.45, high: 34.7, close: 29.31, low: 28.0 },
  { open: 30.2, high: 36.63, close: 36.28, low: 29.8 }
];

detector(candles);

interface IResult {
  bullish: string[];
  bearish: string[];
}

The result contains two arrays listing the patterns found.

You can give a complete history of candles, and the detector itself will take as much as it needs (from the last).
