Stock Predictor trading strategy

Slow Stochastic %K Change Direction

This strategy trades the turning points of the smoothed %K line of the slow stochastic oscillator. Because the line is smoothed, it changes direction less often than the fast %K.

Typical parameters
%K = 5 days

A buy signal is generated when %K changes direction upward and a sell signal when it changes direction downward.

Trading signals

  • Buy when %K(t-2) > %K(t-1) < %K(t) – %K turns up.
  • Sell when %K(t-2) < %K(t-1) > %K(t) – %K turns down.

Strategy rules

IF STO%K[t-2] > STO%K[t-1] < STO%K[t]
   THEN GO LONG
IF STO%K[t-2] < STO%K[t-1] > STO%K[t]
   THEN GO SHORT

Where STO%K[t] is today’s slow %K, [t-1] yesterday’s and [t-2] the value two days ago.
