I face a problem when writing EA

New comment
 

Now, i'm going to write a Hedging EA,

i wanna set that, After i open the 1st trade ( maybe is BUY) price at 1.2300

the second trade will be active if the price at 1.2280, means that, the 1st trade entry price -20 pips,

any one know how to write this out by MQL4?

 

You could either do that using a buystop/sellstop that is placed when the first order is placed.

Or are we tallking completely automated EA ?

 
You should open the trade and at the same time place a sellstop order 20pips below.
 
We are completely talking about automatic ea,not manual trading

Start to write and show the code ....... Then you get the help you want....
 
nt start()
{
//----
if(OrdersTotal()==0)
{
OrderSend(Symbol(),OP_BUY,1,Ask,3,SL,TP,"1234",0123,0,Blue);
}
if(OrdersTotal()==1

&& i wanna to write here, active this trade when the price is under my 1st trade's entry price-200*point)

{
OrderSend(Symbol(),OP_SELL,1,Bid,3,SL,TP,"2345",0321,0,Red);
}
//----
return(0);
}

//+------------------------------------------------------------------+


 
GoDKillz:

Please edit your post . . . If you show your code


Looks like First lines mq4 ever written 

if(OrdersTotal()==0)
{
OrderSend(Symbol(),OP_BUY,1,Ask,3,SL,TP,"1234",0123,0,Blue);
}

If we talk only about this.... .. if(OrdersTotal()==0)

It will fail placing a trade if you have on your account already an open trade it can be also with pendingtrades only open on your account that it fails

So check opentrades on Symbol() and also MagicNumber().... and count the trades

.

Then also you don't check if the ordersend function succeed...

You place the trade with directly a TP and SL setting nowadays a lot of the brokers are ECN and don't allow to place a BUY or SELL trade with directly SL and TP setting. Also Lotsize hard coded... Make it an input....

Also Slippage hard coded you can make it as input parameter

3 is to low in most cases when you work with a 5 digit broker

Make your EA is gonna work as well on 4 as on 5 digit brokers

"1234", 0123 Tradecomment and magicnumber hard coded you could replace it with a

'extern string TradeComment = "1234"; '

'extern int MagicNumber = 0123; '

See if you can change something in a better way.....

 

this is just an example~thanks for ur comment

active this trade when the price is under my 1st trade's entry price-200*point,

but i wan to know, how to translate this sentences to MQL4

Your example is not good

If you wanna write your own EA's then do it good not bad examples we have to help with

How do you check

A The trades of your EA

B If OrderSend succeed....

C EA is working as well on 4 as on 5 digit notation EURUSD

no excusses this is example
