mc,
Went back and reviewed your formula...something didn't seem right.
Below is a corrected version of your indicator and two more using the
Metastock Users guidelines.
MS Users Manual:
The following formula calculates the 12-period Price Rate-Of-Change:
(( C - ref(C,-12)) / ref(C,-12)) * 100
The 12-period rate-of-change can also be written using the roc()
function shown below:
roc( close, 12, % )
The 12-period rate-of-change can be expressed in "points" using the
following formula:
close - ref(close, -12)
Panther ROC Points {corrected}
a:=Mov(C,9,S);
b:=Mov(C,21,S);
wh:=ValueWhen(1,Cross(a,b),C);
If(a>=b,C/wh-1,0)*100
Panther ROC Percentage
a:=Mov(C,9,S);
b:=Mov(C,21,S);
wh:=ValueWhen(1,Cross(a,b),C);
If(a>=b,((C-wh)/wh)*100,0)
Panther ROC Points
a:=Mov(C,9,S);
b:=Mov(C,21,S);
wh:=ValueWhen(1,Cross(a,b),C);
If(a>=b,C-wh,0)
Again thanks for your help with this! I'm sure Yahya will find them
useful.
