How to code? - page 75

Hello all again,

Oops, I am telling lies here, I must have been tired last night when posting this.

It is actually Error #3 which is not the generic error, but "ERR_INVALID_TRADE_PARAMETERS" or Invalid parameters were passed to the trading function, for example, wrong symbol, unknown trade operation, negative slippage, non-existing ticket number, etc. The program logic must be changed.

I can probably fix this by myself later today.

Sorry for the trouble of reading this thread, I got mixed up with the Error reporting from 0,1,2,3 e.t.c instead of 1,2,3!

Can anyone help me with my simple MA EA?

Hello everybody....This is my first post on this board and i am hoping to get some help with this, my first attempt at writing an EA. I am trying to keep it as simple as possible. It's just to learn the code.

But i have hit a snag. The EA compiles ok. But when i run it it never opens an order.

Can anyone tell me what lines to add to get an order to open.

The general idea is just to have an OP_BUY order to open when the simple ma of 1 closes above the sma of 10.

For the purpose of this EA i am not concerned with TP, SL, or short orders.

It's just supposed to open an order every time the sma1 closes above the sma 10.

Any help will be greatly appreciated. And thanks in advanced to Coder Guru and the rest of you guys.

How to change alert into trading EA

Hi Guys,

How do you change an alert indicator into a trading EA?

I've tried changing the command Alert(Symbol()+" "+Period()+" XO Long ",Bid); into OrderSend(Symbol(),OP_BUY,0.01,Ask,3,20,20,"XO-CCI",1,0,Blue); at the start I chose menu to make EA, then content of my alert indicator, i copied to this EA, then I changed the command alert to trading command as above, then i compiled. But the compiled EA is not making any trade after i tried it on 1M chart for a day.

Please help.

Please help...

How come the EA works with my Demo account but not with the Live account. (same set up, same broker, same everything...)

 

I believe some brokers don't allow EA's to be run by default. It might be worth checking with your broker.

Its also possible within the EA to determine if the account is a demo, take a look at the source code and see if the EA uses the function IsDemo, it may be the developer only wanted it to run on demo accounts
