Amplitude is a very simple measurement of subtracting the range (high - low) of a candle by some other data from that candle. in this case, we use the midpoint of the candle, so the calculation is (high - low) / (high + low)/2 . This isn't a new concept, but I could not find this study anywhere so I decided to add it myself.
