iCustom with REI

I don't know the indicator but for your iCustom call to work, it would need to have at least 2 buffers (0 and 1) and would also need to calculate values for the current bar as you are accessing index 0

Grüezi,

double val=iCustom(NULL,0,"RangeExpansionIndex",1,1,0);

of course you are getting always 0.0 (if you are using the REI that can be dldl from the net?)!

Buffer 1  doesn't exist (it has only 1 buffer) and the Period = 1 is what you want?

Thanks to every one,

you brought me on the right track!

 

double rei=iCustom(NULL,0,"RangeExpansionIndex",14,0,0); 

Best Regards!
