  • %D is the slow Stoch line, traditionally represented by the dashed red line on the MT4 graph,

%K and %D are calculated according to the following formula:

Slow %K= 100 [Sum (C – L14) of %K Slowing Period / Total (H14 – L14) of %K Slowing Period]

Slow %D = SMA of Slow %K


  • C = the most recent closing price
  • L14 = the lowest low of the last 14 sessions
