hfzdn_nzl: Can anyone spot the mistake?
- When you post code please use the SRC button! Please edit your post.
General rules and best pratices of the Forum. - General - MQL5 programming forum if(OrdersTotal()==0) ... else if(OrderSelect(n-1,SELECT_BY_POS,MODE_TRADES))
Using OrdersTotal directly and/or no Magic number filtering on your OrderSelect loop means your code is incompatible with every EA (including itself on other charts and manual trading.)
Symbol Doesn't equal Ordersymbol when another currency is added to another seperate chart . - MQL4 and MetaTrader 4 - MQL4 programming forumfor(int n=0 ; n<=9 ; n++){ else if(OrderSelect(n-1,SELECT_BY_POS,MODE_TRADES))
If n is zero then the OrderSelect will always fail.if(OrderSend(Symbol(),OP_BUY,lots[n],Ask,3,Ask-sl*Point,Ask+tp*Point,NULL,n,0,Green)){}
Check your return codes for errors and report them.
What are Function return values ? How do I use them ? - MQL4 and MetaTrader 4 - MQL4 programming forum
Common Errors in MQL4 Programs and How to Avoid Them - MQL4 Articles-
You buy at the Ask and sell at the Bid.
- Your buy order's TP/SL are triggered when the Bid reaches it. Not the Ask.
-
Your sell order's TP/SL will be triggered when the Ask reaches it. To trigger at
a specific Bid price, add the average spread.
MODE_SPREAD (Paul) - MQL4 and MetaTrader 4 - MQL4 programming forum - Page 3 - The charts show Bid prices only. Turn on the Ask line to see how big the spread is (Tools -> Options {control-O} -> charts -> Show ask line.)
- Same as Martingale: Martingale, guaranteed to blow your account eventually.
