OrderModify (ECN)

I'm just having a little trouble figuring out the best way to utilise OrderModify on an ECN broker.

Basically, I place the order first:
ticket=OrderSend(Symbol(),OP_BUY,Lots,Ask,Slippage,0,0,"Test EA",16384,0,Green);

Then the next line have:
OrderModify(ticket,OrderOpenPrice(),Ask-Point*StopLoss,Ask+Point*TakeProfit,0,Green);

However, if the market is moving quickly then the takeprofit and stoploss will not be placed relative to the entry position, but instead be applied to the Ask at the time it is modified.

I tried the following:
OrderModify(ticket,OrderOpenPrice(),OrderOpenPrice()-Point*StopLoss,OrderOpenPrice()+Point*TakeProfit,0,Green);

However that throws an error in the console and doesn't accept the modify order.

Any ideas? Thanks!

OrderModify(ticket,0 ,OrderOpenPrice()-Point*StopLoss,OrderOpenPrice()+Poi nt*TakeProfit,0,CLR_NONE);

The OpenPrice() you used can only be utilized with Pending Orders. (Cant change the OpenPrice of a Market Order) - Also I notice you put Green in there - Do you really want to see when the Modify happened? It'll overwrite the NEWOrder Arrow.

I'm not sure if I was entirely clear.

Basically, the OrderSend line is immediately followed by the OrderModify as the ECN I am using does not let me set SL & TP in the same line.

Thus, when the market is moving quickly it sets SL & TP relative to the moved ask price instead of the open price.

I want to set SL & TP relative to the actual order opening price, hence why I was using OrderOpenPrice() in the OrderModify line.

OrderModify is defined as:
bool OrderModify( int ticket, double price, double stoploss, double takeprofit, datetime expiration, color arrow_color=CLR_NONE)

so I should have:
OrderModify(ticket, OrderOpenPrice(), <<stoploss relative to order open price>>, <<takeprofit relative to order open price>>, 0, CLR_NONE)

What I want to know is what I should use between those <<>> in that line

Again... The FIRST Openprice () is the problem (ONLY Pending orders allow the OpenPrice to be altered). I have ECN compatible code- Here a working snippet:

OrderModify(ticket,0,NormalizeDouble(OrderOpenPrice()+(StopLoss*Point),Digits),0,0,CLR_NONE); Also unless you used OrderSelect() the OrderOpenPrice() has NO Value... - You can do askprice=Ask; THEN do your OrderSend and OrderModify using the Variable askprice.

double askprice=Ask;
ticket=OrderSend(Symbol(),OP_BUY,Lo ts,askprice,Slippage,0,0,"Test EA",16384,0,Green);
// bool xbool = OrderSelect(ticket, SELECT_BY_TICKET); - optional in this example
OrderModify(ticket,0,askprice-Point*StopLoss,askprice+Point*TakeProfit ,0,CLR_NONE);

if you had the used the OrderSelect() then you could use OpenOrderPrice() - NOT needed in the above example..

Ah, the reason I queried you is because when running the EA on a live account it would accept the OrderModify with the first OrderOpenPrice(), but not if I used it to specify TP & SL.

I will use your suggestion, thanks!

Oh.. but can you do that for the OrderSend? If the Ask price changes between the assigning of the double value and the execution of OrderSend, won't it reject the order?

Ah, wait I see..

I should ideally use OrderSelect, got it. That's what I'll do.. sigh

ticket=OrderSend(Symbol(),OP_BUY,Lo ts,askprice,Slippage,0,0,"Test EA",16384,0,Green);
bool xbool = OrderSelect(ticket, SELECT_BY_TICKET);
OrderModify(ticket,0,OrderOpenPrice()-Point*StopLoss,OrderOpenPrice()+Point*TakeP rofit ,0,CLR_NONE);

Yep, if you use the OrderSelect() then you can do it like you intended (without trying to modify the price of an existing order) - Also you dont have to worry about the price changing. These commands execute in milliseconds. You actually can do quite a bit between statements with no worries.

Thanks again!
