EA Modification

How do I modify an EA to use on an ECN Broker?
Does anyone have an example?

Thanks

hey rc....you can send the orders with no profittarget and stoploss..... then modify the orders after placed .....

or you can use orderreliable2step..... you'll need the include liborderreliable.....

both methods work perfectly...... below is code from an ecn ea of mine as an example......h

Its easy. Send all orders with NO TP/SL. on the next line add the TP/SL with OrderModify();

hello; how can change this code for ECN mt4; many thanks
