Hi all,

I am trying to create a simple indicator that tracks the movements of the account equity and provides 2 values:

Buffer 0=account equity (taken from another indicator with iCustom function)

Buffer 1= simple moving average of the account equity


For Buffer 0 everything is fine, I cross checked with the original indicator.

For Buffer 1 there is no way to get correct values...I get an extremely high value on the average, that has no sense.

can you please help me?

Thanks a lot

ciao

for(int a=200;a>0;a--) ExtMapBuffer2[a]=iMAOnArray(ExtMapBuffer1,0,MAPeriod,0,MODE_SMA,0);

maybe you mean

for(int a=200;a>0;a--) ExtMapBuffer2[a]=iMAOnArray(ExtMapBuffer1,0,MAPeriod,0,MODE_SMA,a);

and the first buffer should be filled by at least a+MAPeriod
