Pls help... Order triggered order EA problem
if (OrdersTotal < 1){ OrderSend(Symbol(), OP_BUY, Lot, Ask, 3, 0, Bid+1*Take_Profit*Point, "Long at 1.3400", 1000, NULL, Lime); OrderSend(Symbol(), OP_BUYLIMIT, Lot, Ask-1*Take_Profit*Point, 3, 0, Bid, "Long at 1.3390", 1001, NULL, CLR_NONE); OrderSend(Symbol(), OP_SELL, Lot, Bid, 3, 0, Ask-1*Take_Profit*Point, "Short at 1.3400", 9000, NULL, Red); OrderSend(Symbol(), OP_SELLLIMIT, Lot, Bid+1*Take_Profit*Point, 3, 0, Ask, "Short at 1.3410", 9001, NULL, CLR_NONE); }

I didn't debug the code so so just fix up any errors you encounter.
Also you should be normalising your doubles or you are headed from problems.

kennyhubbard hasn't posted here in almost 2 years, why are you dredging up a thread that is almost 3 years old ? It would be a good idea to delete this post and start your own thread, it's up to you though . . . but . . .

recently i'm writing about grid concept EA, however face some order management source code problems:
1) EA supposes to open only 4 orders, HOWEVER, at each tick, the EA is opening many and many same 4 orders..
2) After an order is closed due to take profit point hit, EA will triggered to open a same new order, HOWEVER, no new order is opened after TP is hit..
Please do give your opinion how to resolve above 2 problems.. attached below is the FULL source code for this Order Triggered Order EA.
(If possible, please give a FULL WORKING source code?) :)
Thank you very much, sir.

//SECTION 1:
// (1) When EA activated, 4 orders will be opened ONCE only,
// that is 1 instant OP_BUY, 1 instant OP_SELL, 1 pending OP_BUYLIMIT and 1 pending OP_SELLLIMIT.
// (2) Problem at SECION 1: After EA activated, these 4 orders are opened MANY MANY times (everytime new tick, 4 new orders are opened AGAIN)
// (3) Your opinion : How to write the code in SECTION 1 so that once EA runs, it ONLY opens 4 orders?

//SECTION 2:
// (1) At SECTION 2, when ANY ONE of above 4 orders is closed (due to take profit), EA will triggered to:
// (a) RE-OPEN SAME with previous order properties.
// (b) The process at (a) will repeat UNLIMITED times (Hit_TP_&_closed -> Reopen_same_order... Hit_TP_&_closed -> Reopen_same_order...)
// (Example: Say EURUSD market price is at 1.3400, then price move down to 1.3390 and hit the OP_BUYLIMIT.
// After a while, market price retraced to 1.3400, so take profit is achived, so earlier OP_BUYLIMIT is closed now.
// At this moment, EA is triggered to send a NEW same with previous order:
// OP_BUYLIMIT 0.1Lot at order price 1.3390, TP at 1.3400 and magic number 1001 =>same properties with earlier order.
// The EA will repeat the same, as long as TP is hit)
//
// (2) Problem at SECION 2: When one of the order TP is hit, there is NO new same properties order is Re-opened.
// (3) Your opinion : How to write the code in SECTION 2 so that the TP hit can trigger to send a new same properties order?
// That is when market price hit one TP, EA will be triggered to Re-open one new same properties order.
