New versions of Metastock allow you to choose a data array ... Another solution is to use the forum dll rsi function .... Another Solution is to create a custom formula for RSI such as the one in the formula collection ... http://forum.equis.com/v...cabbe0f60d96a28ac3a89350 Patrick :mrgreen:

Hey vinclanz- Welcome to the forum! Assuming that 'mid point' is similar to typical(), you might try this example: { Indicator } periods:=Input("Typical Price Periods",1,100,20); periods:=(2*periods)-1; method:=Typical(); 100 - 100/(1+ If(Mov(If(method-Ref(method,-1)<0,-(method-Ref(method,-1)),0),periods,E)=0,1000000, Mov(If(method-Ref(method,-1)>0, method-Ref(method,-1), 0),periods,E) /Mov(If(method-Ref(method,-1)<0,-(method-Ref(method,-1)),0),periods,E) )); note: you can replace 'typical()' with any valid data array { Explorer } Column A [RSI] RSI(Typical(),5); Column B [NEW RSI] periods:=5; periods:=(2*periods)-1; method:=Typical(); 100 - 100/(1+ If(Mov(If(method-Ref(method,-1)<0,-(method-Ref(method,-1)),0),periods,E)=0,1000000, Mov(If(method-Ref(method,-1)>0, method-Ref(method,-1), 0),periods,E) /Mov(If(method-Ref(method,-1)<0,-(method-Ref(method,-1)),0),periods,E) )); note: change the 'periods:=5;' line to reflect whatever RSI periods you are looking for

That's the trouble with you P... always thinking small! #-o
