Hello, I need to calculate future value for SAR, Ref(SAR,1) works good until last bar, and the last bar is most important for me because I want to use it in the system which relies on tomorrow's open price. In short, I would like to imlement this formula in AmiBroker:
SAR next day = SAR today + AccelerationFactor( highest high reached yesterday - SAR today) // got this formula here<http://wiki.answers.com/Q/What_is_the_Parabolic_SAR_formula> This is what I have so far: // SAR today AF = 0.02; tSAR = SAR(AF,0.2); // This is number of bars after last "swap" of trend barSAR = Min(BarsSince(Cross(tSAR,H)),BarsSince(Cross(L,tSAR)))+1; // And finally here is my attempt to calculate next day SAR, // but results are not always the same as AmiBroker SAR ;( // I guess I have to skip acceleration in some cases, but // don't know how to implement this in AB... *nSAR = tSAR + AF * barSAR * (LLV(L,barSAR) - tSAR);* Could you help me with this ? Best regards, Tomek
