// Name: Price Action Candlesticks v0.1 by JustUncleL
// By: JustUncleL
// Date: 16-Aug-2016
// Version: v0.1
//
// Description:
//   Identifies the candlestick patterns as used in
//   "Price Action Battle Station by theforexguy". All the identification 
//   of PA candles is dissabled by default.
//   The patterns identified are:
//   - Dark Cloud Cover : large body bull candle followed by large body
//       bear candle that covers the upper bull candle and closes in the
//       lower 50% of bull body.
//   - Piecing Line : large body bear candle followed by large body
//       bull candle that covers the lower bear candle and closes in the
//       upper 50% of bear body.
//   - Doji (aka spinning top): small or no body candle with wicks top and 
//       bottom that are at least 30% of candle.
//   - Bullish Engulfing: a bear candle followed by a larger bull candle
//       whose body covers the bear candle including the upper wick.
//   - Bearish Engulfing: a bull candle followed by a larger bear candle
//       whose body covers the bull candle including the lower wick.
//   - Outside Bar: a small inner candle followed by a large outer candle. 
//       The outer candle covers the whole inner candle (wick to wick)
//   - Outside Bar: a large inner candle followed by a small outer candle. 
//       The inner candle covers the whole outer candle (wick to wick)
//   - Upper Shadow Pin Bar (aka shooting star, inverted hammer, bull rejection) : 
//       a small body bear (red) candle followed which has a large upper wick
//       and a small lower wick.
//   - Lower Shadow Pin Bar (aka hammer, hanging man, bear rejection) : 
//       a small body bull (green) candle followed which has a large lower wick
//       and a small upper wick.
//
// references:
//  - Inside/Outside Bars and Pin Barsome calculations based on
//        "CM_Price-Action-Patterns Price Bars That Work! by chrismoody"
//  - Other candles, although they all needed correcting, based on
//        "All Candlestick Pattern identifier by alona.gz"
