This script help to identified popular candlestick pattern combined with trend identifier. Most script only focus on criteria of the pattern. Such as how much the length of the body compared to previous candle etc. Besides criteria of the candle, this script also considered the trend into the logic. For example bullish engulfing is a bullish reversal signal, which is only valid in a down trend.
To identified trend, I'm using RSI. Normally, RSI less than 50 is considered a down trend, and RSI greater than 50 is considered up trend. In this script, you can customize the criteria of how much RSI is up trend and down trend. Default value RSI >= 55 is up trend, RSI <= 45 is down trend.
