MovingAv_EA (EURUSD-D1,ALPARI)v1.0.mq4 (6.1 KB, 15 views)

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.

The solution to my problem was easy...this new version works just fine. Take out the OrdersTotal line and run it on a 1 min timeframe and watch your account double or bust every single day practically.

Give me a break already, i've had no formal training!!!!

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.

Hi!!

I'm writting my own EA. All seems ok in backtest but when I run it in forward I get some errors because of requotes. Curiously I've got this errors 3 times and the 3 times has been on GBPUSD (I'm testing the EA in 20 pairs). I've coded a maximum slippage of 5. I tink I get this errors even when the requote is less than 5, so I don´t understand.

Here is the error message:
2008.03.05 08:15:12 EA1 GBPUSD,M15: Error opening SELL order! invalid price

And the requote message:
2008.03.05 08:15:11 '5267460': requote 1.9803 / 1.9807 for open sell 0.10 GBPUSD at 1.9807 sl: 1.9957 tp: 1.9357
2008.03.05 08:15:11 '5267460': request was accepted by server
2008.03.05 08:15:11 '5267460': instant order sell 0.10 GBPUSD at 1.9807 sl: 1.9957 tp: 1.9357

So if the requote is 1.9803/1.9807 and the is trying open an order at 1.9807 and a slippage of 5 pips is accepted, why this error?

Finally the piece of the code for open position:

void BuscarAbrir()
{
int Slippage=10;
int MagicNumber;
string symbolo=Symbol();
if (symbolo=="GBPUSD"){MagicNumber=185258471411;}
if (symbolo=="EURUSD"){MagicNumber=458555788512;}
if (symbolo=="NZDUSD"){MagicNumber=129999996613;}
if (symbolo=="USDCAD"){MagicNumber=123456741814;}
if (symbolo=="USDCHF"){MagicNumber=111112225415;}
if (symbolo=="EURCHF"){MagicNumber=128588888216;}
if (symbolo=="EURJPY"){MagicNumber=745698523657;}
if (symbolo=="GBPJPY"){MagicNumber=555555555228;}
.
.
.
if (anterior && (comentar != -1))
{
if (Kumo == 1) Print("SELL signal");
enviar = "SELL signal";
int ticket = 0;
Arko = 0;
while ((ticket <= 0) && (Arko < Number))
{
while (!IsTradeAllowed()) Sleep(5000);
ticket = OrderSend(Symbol(),OP_SELL,LotsRisk(StopLoss),Bid, Slippage,Bid + StopLoss * Point,Bid - TakeProfit * Point,Version,MagicNumber,0,Red);
if (ticket < 0)
{
Print("Error opening SELL order! ",ErrorDescription(GetLastError()));
var_116 = "Error opening SELL order! " + ErrorDescription(GetLastError());
Arko++;
}
}
comentar = -1;
}
else
{
if (posterior && (comentar != 1))
{
if (Kumo == 1) Print("BUY signal");
enviar = "BUY signal";
ticket = 0;
Arko = 0;
while ((ticket <= 0) && (Arko < Number))
{
while (!IsTradeAllowed()) Sleep(5000);
ticket = OrderSend(Symbol(),OP_BUY,LotsRisk(StopLoss),Ask,S lippage,Ask - StopLoss * Point,Ask + TakeProfit * Point,Version,MagicNumber,0,Blue);
if (ticket < 0)
{
Print("Error opening BUY order! ",ErrorDescription(GetLastError()));
var_116 = "Error opening BUY order! " + ErrorDescription(GetLastError());
Arko++;
}
}
comentar = 1;
}
}
}


Thanks for your help and sorry if my english is no very good.

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

Hi danielp!! Are you from fxreviews blog? I can help you for coding.
