Help with make a very simple Ea - page 2

 
RaptorUK:

Do you realise that Close[0] = Bid ? it changes as Bar 0 is forming . . . bar 0 never has a fixed Close price, when it is actually closed it becomes Bar 1 . . .

Perhaps you should post the latest version of your code.


Yes I now, but the problem is, that my EA opens only one trade per Bar. I want to make new buy order when Close[0]>Open[0] and Close it when Close[0]<Open[0] and vise versa for sell.

here is the code.please tell me why it does not make new orders by Bid movement relating to Open[0] !?

RaptorUK:

You need to make use of the variable you have created for the return value from OrderSend . . res, check it to see if the OrderSend worked, if it didn't print the error and you will be in a better position to fix your own issues.

Your Orders do not take into account spread . . Buy at Ask, but a Buy is closed with a Sell and a Sell is executed at Bid.

You need to do this . . .

Yes I now, but the problem is, that my EA opens only one trade per Bar.

After the first trade is placed bartime = Time[0]; so you cannot place more than 1 trade per bar . . your code does not allow it.

if(OrdersTotal()<1 &&    bartime != Time[0]  )
 
I want to make new buy order when Close[0]>Open[0]

and on the first tick of the bar Close[0] == Open[0]

so your 2 criteria are mutually incompatible.

yes you are right, then i do not used Close[0] >= Open[0] or Close[0] <= Open[0]...

exactly when the current close 1 tick more or less than current Open is, we make new reversal trade and close the other one, but i do not know how to do this.

yes you are right, but how can i repair it?

i do not know how to make reversal code for several position on 1 bar?

Well what have you tried ? I'm not writing your code for you . . .
 
Unfortunatly i am not a coder, i used other Ea codes and assembeld it. I know about mql codes. I want to know what should i change in the above code in order to permiting several trade in 1 bar?
