Candlestick Checker

Use the most popular candle stick patterns to reinforce the signals of your trading indicators. This tiny library focuses on simplicity.

It groups the patterns into three main sections:

Single Candle Pattern	Double Candle Pattern	Triple Candle Pattern
BullishDoji	BullishEngolfer	BullishMorningStar
BullishHammer	BullishPiercing	BullishWhiteSoldiers
BearishDoji	BullishTweezerBottom	BullishKicker
BearishShotingStar	BearishEngolfer	BearishEveningStar
	BearishDarkCloudCover	BearishThreeBlackCrows
	BearishTweezerTop	BearishKicker

But instead of worrying about each one of them or checking it one by one, this tiny lib evaluates all of them returning only a bullish or bearish signal.

Simple Usage

I prefer to check for all in one like in the example bellow, but if you prefer, you may check individually.

// CHECK FOR ALL CANDLE STICK PATTERN

// if you are in a downtrend, check for bullish signals
boolean isSingleBullish = CandleStickFactory.single(candles).isBullish();
boolean isDoubleBullish = CandleStickFactory.doubl(candles).isBullish();
boolean isTripleBullish = CandleStickFactory.triple(candles).isBullish();

if(isSingleBullish || isDoubleBullish || isTripleBullish){
  // if you are in a downtrend and your trending signal are indicating
  // a possible turn over to an uptrend, this could be the right moment to 
  // buy a position. It should act as a reinforcement of your indicators
  
  // ... do something here...
}

// if you are in an uptrend, check for bearish signals
boolean isSingleBearish = CandleStickFactory.single(candles).isBearish();
boolean isDoubleBearish = CandleStickFactory.doubl(candles).isBearish();
boolean isTripleBearish = CandleStickFactory.triple(candles).isBearish();

if(isSingleBearish || isDoubleBearish || isTripleBearish){
  // if you are in an uptrend and your trending signal are indicating
  // a possible turn over to a downtrend, this could be the right moment to 
  // sell a position. It should act as a reinforcement of your indicators
  
  // ... do something here...
}
