Automated increasing of lots in EA

forexfordinner · #1 (**permalink**) 09-04-2006, 06:43 AM

Hello,

I am trying that my EA would calculate automatically the proper lots based on available margin.

ContractSize=NormalizeDouble((((AccountFreeMargin( )*AccountLeverage())/Ask)/10000),1);

I've placed this line after the start() and before the ordersend. Of course the ordersend takes the lot size from here.

This is supposed to do it, but it doesn't works. Can anyone tell me WHY???

I don't know about your particular question but i found library file inside my computer (attached). Unzip it and place to /include folder. Don't compile.
And in your EA do the following:

- place

Code:

#include <b-Lots.mqh>

after the settings of EA but before deinit(), init() and start()

- place

Code:

Lots=GetSizeLot();

before OrderSend(Symbol(), ...

- delete this line in your EA:

Code:

extern double Lots=1;

And you will have several kinds of Money management:
LotsWayChoice = 1; // 0-fixed lot size.
// 1-% from deposit,
// 2-the other kind of MM
// 3-different kind of MM

This library includes just one function so u can just copy/paste it to your ea and it will work in the same way as it it work with external file.

Hí guys,

I did try to copy and paste the script in my EA...... well, I tried many ways but none seems to work. So this might sound very amateur..... could you pls indicate my where to paste it? And in the place for indicating the lots in the order send sentence, what should I write? dLot? Get...()?
Thanks in advance

First u shoud copy initial parameters (before init function) to your ea in the same place (in your ea also before init function) then just copy the GetSizeLot() after start function (this function should be added to ea after start function is closed or before start function - it is important to not to place this function inside start()) and then u can call GetSizeLot() in your ea inside the start function.
If u still have a problem with that just post your ea here I will help u to combine it.
