Stochastic Forex and Binary Options Strategy


Stochastics are an oscillator developed by George Lane and are based on the following observation:

As prices increase – closing prices tend to be closer to the upper end of the price range

As prices decrease – closing prices tend to be closer to the lower end of the price range. Fast Stochastics consists of two lines, % K and %D:

The %K line measures, as a percentage, where the current close is, in relation to the lowest low over the observation period. This is shown on a scale of 0 to 100, where 0 is the observation period low, and 100 is the observation period high.

The %D line is a Simple Moving Average of the %K. Because it is a moving average, this line is smoother than the %K and provides the signals for an overbought/oversold market.

Fast Stochastics are more sensitive than Slow Stochastics and therefore more likely to give false signals. As a result Fast Stochastics are less commonly used than Slow Stohastics.

The most common uses of Stochastics in Forex and Binary Options Strategies are to:

  • Indicate overbought and oversold conditions

An overbought or oversold market is one where the prices have risen or fallen too far and are therefore likely to retrace. If the %D line is above 80% then the close is near the top end of the range of the observation period, while a reading below 201% means that a close is near the bottom of the range of the observation period.

Generally the area above 80 is considered overbought, while the area below 20 is oversold. The specified overbought/oversold ranges vary. Other commonly used ranges include 75-25, 70 -30 and 85 -15. Overbought and oversold signals are most reliable in a non-trending market where prices are making a series of equal highs and lows.


If the market is trending, then signals in the direction of the trend are likely to be more reliable. For example if prices are in an up trend, a safer trade entry may be obtained by waiting for prices to pullback giving an oversold signal and then turn up again.


  • Generate buy and sell signals

For a buy or sell signal, the following conditions must be met in order.

  1. The %K and %D line move above 80 or below 20
  2. The %K and %D line cross
  3. The %K and %D lines move below 80 or below 20


  • Indicate Bullish and Bearish Divergence

Divergence between Stochastics and the price indicates that an up or down move is weakening. Bearish Divergence occurs when prices are making higher highs but the Stochastics are making lower highs. This is a sign that the up move is weakening. Bullish Divergence occurs when prices are making lower lows but the Stochastics are making higher lows. This is a sign that the down move is weakening. It is important to note that although Divergences indicate the weakening trend, they do not in themselves indicate that the trend has reversed. The confirmation or signal that the trend has reversed must come from price action, for example a trend line break.


Parameters Observation Period for %K FAST: (default 5) Observation Period for %D FAST: (default 3)

A value greater than the default results in a smoother less sensitive %K Fast line. The averaging period is the number of observations of %K FAST lines used in the moving average. The smaller the value, the close the %D will be to the %K
