Harami Scanner
This script searches for the popular Bullish and Bearish Harami patterns. This pattern is characterised by having a pregnant appearance; the doji is the pregnant body, and the taller candle is the mother. I've written this script to be as lenient as possible with the detection, so its still up to you to determine if it looks like an actual Harami, or perhaps it looks more like an engulfing or Marubozu!
