Auto Order Block by D. BrigagliaThis indicator finds trend following engulfings, and draws order blocks based on the 1st candle's range (the first candle of the engulfing pattern).
It does filter the trend with simple moving averages of 21 and 55 periods, but it doesn't filter for retracements in the trend (you should consider only the order blocks that are coming from engulfings after a retracement)
