Derivative Moving Average

The information for this test was published in the June 1996 issue of "Technical Analysis of Stocks and Commodities". The test appears in the article "The Derivative Moving Average" by Adam White, page 18. Mr. White describes this test as using a variation of the "tried-and-true simple moving average for entry signals and the "trend analysis index" for exit signals.

**System syntax:**

ENTER LONG:

When(Ref(Mov(C,28,S),-1),=,LLV(Mov(C,28,S),4))

CLOSE LONG:

When(Fml("TAI"),<,0.4) AND When(Ref(Fml("TAI").-1),>=,0.4)

TAI formula:

((HHV(Mov(C,28,S),5)-LLV(Mov(C,28,S),5))/C)*100
