Martin Pring's KST Formulas

The KST indicator was developed by Martin J. Pring. The name KST comes from "Know Sure Thing". The KST is constructed by summing four smoothed rates of change. For more interpretation refer to Martin Pring's article "Summed Rate of Change (KST)" in the September 92 issue of TASC.

The following formulas are MetaStock formulas for the KST:

DAILY KST SIMPLE MOVING AVERAGE
(Mov(Roc(C,10,%),10,S)*1) + (Mov(Roc(C,15,%),10,S)*2) + (Mov(Roc (C,20,%),10,S)*3) + (Mov(Roc(C,30,%),15,S)*4)

LONG-TERM MONTHLY KST SIMPLE MOVING AVERAGE
( (Mov(Roc(C,9,%),6,S)*1) + (Mov(Roc(C,12,%),6,S)*2) + (Mov(Roc(C ,18,%),6,S)*3) + (Mov(Roc(C,24,%),9,S)*4) ) / 4

INTERMEDIATE KST SIMPLE MOVING AVERAGE
(Mov(Roc(C,10,%),10,S)*1) + (Mov(Roc(C,13,%),13,S)*2) + (Mov(Roc (C,15,%),15,S)*3) + (Mov(Roc(C,20,%),20,S)*4)

INTERMEDIATE KST EXPONENTIAL MOVING AVERAGE
(Mov(Roc(C,10,%),10,E)*1) + (Mov(Roc(C,13,%),13,E)*2) + (Mov(Roc (C,15,%),15,E)*3) + (Mov(Roc(C,20,%),20,E)*4)

LONG-TERM KST EXPONENTIAL MOVING AVERAGE
(Mov(Roc(C,39,%),26,E)*1) + (Mov(Roc(C,52,%),26,E)*2) + (Mov(Roc (C,78,%),26,E)*3) + (Mov(Roc(C,109,%),39,E)*4)

SHORT-TERM KST WEEKLY EXPONENTIAL MOVING AVERAGE
(Mov(Roc(C,3,%),3, E)*1) + (Mov(Roc(C,4,%),4, E)*2) + (Mov(Roc(C,6,%),6, E)*3) + (Mov(Roc(C,10,%),8, E)*4)
