Remarks
%D Fast is a part of the Stochastic Oscillator. Stochastic Oscillator is a momentum indicator that measures the price of a currency or commodity relative to the high/low range over a set period of time. The indicator oscillates between 0 and 100, with readings below 20 considered oversold and readings above 80 considered overbought. A 14-period Stochastic Oscillator reading of 30 would indicate that the current price was 30% above the lowest low of the last 14 days and 70% below the highest high.
The Stochastic Oscillator can be used like any other oscillator by looking for overbought/oversold readings, positive/negative divergences and centerline crossovers.
