Hi Russ,
The MetaStock PREV function is a strange
function that represents the previous value of the function which contains it.
I chose to write a loop to calculate the indicator values. Your indicator
looks interesting; what is it called and how do you use it?
The following code was written for
readability to help explain the PREV function, not minimal code optimization (although
the code is fast as written):
// MetaStock Code
//
if(LinearReg(C,13)>PREV,if(LinearReg(C,13)-(ATR(13)*2.5)>PREV,
// LinearReg(C,13)-(ATR(13)*2.5),PREV),LinearReg(C,13));
periods = Param("periods", 13,2,100,1);
LR = LinearReg(C,periods);
LR_ATR = LR - (ATR(periods)*2.5);
MyInd = 0; // Indicator to calculate, MyInd[i-1] = MetaStock PREV
PREV = 0;
for (i=periods; i<BarCount;
i++) {
PREV[i] = MyInd[i-1];
if(LR[i] > PREV[i]) {
if(LR_ATR[i] > PREV[i])
MyInd[i]
= LR_ATR[i];
else
MyInd[i]
= PREV[i];
}
else
MyInd[i]
= LR[i];
}
Plot( MyInd, "My Indicator", ParamColor("My Ind color", colorRed ), ParamStyle("My Ind
style") );
Regards,
David

converting metastock code
Hi re a lower deviation metastock can someone help
convert to
Amibroker. I use version 4.6
Metastock code:
If(LinearReg(c,13)>PREV,If(LinearReg(C,13)-(ATR(13)*2.5)>PREV,LinearReg(C,13)-(ATR(13)*2.5),PREV,LinearReg(C,13));
