It calculates the number of occurrances of up closes and down closes of the current close compared to the close between the last 11 to 21 candles ago. Whenever the current candle closes above the candle 11 bars ago, the count is incremented. Whereas if the current candle closes below the candle 11 bars ago the count is decremented.
