Bullish and Bearish Engulfing Candles in ThinkorSwim

Engulfing pattern on your candlestick chart can be useful for identifying trend changes, potential reversal play, etc. Here is an indicator for ThinkorSwim that will automatically find and highlight Engulfing candle on your chart. Both bullish and bearish engulfing patterns.

I also included labels and a unique color for each type of pattern. By default, a bullish engulfing candle will be yellow and a bearish engulfing candle will be purple. You can change this via the source code. This works for any timeframes.

P.S: To fix the shrinking issue, be sure to untick "Show Plot" for Bullish and Bearish options in the indicator's setting.

@BenTen I know it's been a year, but I'm very new to trading and I've been studying patterns. How do I get my chart to this on TOS? I'm just paper trading right now and it'd be nice to see this live, while I'm learning.
 
Hello!

Does anyone have any way to scan for an engulfing pattern bullish? There are indicators on this site for bullish patterns, but there are no scanners for them.
