Am inceput sa fac un expert simplu pentru a invata mql4.
Am facut un expert care cumpara pe baza de iMA() [medii mobile].Daca linia trece peste alta linie intra pe pozitie in buy. Am compilat EA-ul si nu are errors sau warnings.Il testez cu strategy tester si nu imi deschide nici un ordin.Eroarea este : CITAT OrderSend error 138 invalid double number as parameter 6 for OrderSend function Functia de order send arata asa : CITAT extern double StopLoss =35; extern double TakeProfit =75; .... if (Curs>MA1){ tiket=OrderSend(Symbol(),OP_BUY,Lots,Ask-StopLoss*Point ,Ask+TakeProfit*Point,"Tunel",0,0,Red); if (Curs<MA1) { OrderClose(tiket,Lots,Ask,Red); return(0); } } In codul de mai sus am vrut sa spun cand "Curs" trece deasupa lui "MA1" deschide un ordin buy iar cand "Curs" ajunge sub "MA1" inchide ordinul deschis precedent. Nu imi dau seama unde poate fi greseala. Alta intrebare: Care este diferenta intre a declara indicatorii in functia init() si in functia start ()? |

QUOTE(Mangusta @ Apr 19 2008, 11:46 AM)  tiket=OrderSend(Symbol(),OP_BUY,Lots,Ask-StopLoss*Point ,Ask+TakeProfit*Point,"Tunel",0,0,Red); ai o mancat ceva cuvinte din propozitie:double price, int slippage, tiket=OrderSend( string symbol, int cmd, double volume, double price, int slippage, double stoploss, double takeprofit, string comment=NULL, int magic=0, datetime expiration=0, color arrow_color=CLR_NONE) deci corect ar fi: tiket=OrderSend(Symbol(),OP_BUY,Lots,Ask,3,Ask-StopLoss*Point ,Ask+TakeProfit*Point,"Tunel",0,0,Red); -------------------- |

@nicugh
Multumesc pentru raspuns. Cum inchid ordinul deschis mai sus ? Eu m-am gandit sa folosesc functioa OrderClose in interiorul primului if care deschide ordinul.[Vezi in primul post codul] |
