I have a Amibroker Explorer.The result of it should trigger Order creation. The code I have written, I have giving here. It is is plain code without any bells and whistle. I am not sure if this code I am writing is in right direction or not. Your suggestion/input will help. =========================== cond=(buyma OR sellma) AND comb;//Explorer works fine with this Filter=cond; ORder = IIf(buyma AND comb,1,IIf(sellma AND comb,2,0)); if(BsCond>0) { brd = CreateStaticObject("pibridge.Bridge"); NTrdSymbol = Name()+"-EQ"; prevO = Ref(O,-1);//previous bar's open prevC = Ref(C,-1);////previous bar's close cond=(buyma OR sellma) AND comb; ooo=ValueWhen(cond,prevO,1); ccc=ValueWhen(cond,prevC,1); if (Order==1) { NPrice=ooo; NOrder="BUY"; } if (Order==2) { NPrice=ccc; NOrder="SELL"; } brd.PlaceOrder ("NSE", NTrdSymbol,NOrder,NPrice, 100,.....); ==================================================================
