I am using the iSAR-Function in my EA. It is returning an accurate result. When, however, I try to add something, it returns 0: double SAR_C = iSAR(NULL,0,0.02,0.2,1)+0.00005; Print("SAR_C: "+SAR_C); This prints "SAR_C: 0.00000". Why is this? How can I prevent this/add something to the iSAR-Result?
