Thanks

I guess you deleted something and forgot:
it's nonsense.

Delete 1=, and 2= before OrderSend(....

Thanks man

Can you teach me how to create EA based on this indis ? when the arrow appear on the screen and that's the time EA auto enter position, can it be done ? please guide me as i'm keen in learning =^_^=

See this guide really good material MQL4 Tutorial

Here is the above mentioned arrow signal, need someone to guide me on the EA coding

Thanks anyone out there =^_^=

Does anyone have good code for trading multiple orders when running up against the maxlot barrier?

IE Broker only allows lots of 5, and you want to trade 10, so the function will trade 2 x 5 lot orders instead.

I'm looking for more than just a simple loop here. The problem is that a simple loop will not always fully complete, and you could be left with only a partial order open.
