Lotsize = AccountBalance()*0.00001;

And I very strongly suggest using AccountEquity() instead...

Thank you very much. It works, but it doesn't update when equity changes. Where do I have to put it to update on every trades?

That be in the structure of the code, you'll have to move where you do the calculation. And of course without seeing the source I'd have no idea why it's not updating every tick.

Try this line in a few places till you get the desired result, look for the values to print in the experts tab:

Print ('Ordersize: ', AccountBalance()*0.00001);

If you put that just after you initiate the code it should print constant value changes, then move it around to few places where you think it should be. I don't know where your lotsize declaration is, if it's global you can just put your calculation where it prints ok, if it's not global then you'll have to change your logic to update more often.

And of course I just used lotsize, what is your parameters name in the OrderSend ?

Look for an OrderSend function in your code, get the name of the third parameter, then go look where you work out that parameter and put that calculation in there.

Print ('Ordersize: ', AccountEquity()*0.00001);

would be better to see constant updated Lot Size.
 
Or if you want it straight on your chart:

string Text='Lot Size: '+DoubleToStr(AccountEquity()*0.00001,2);

Oops, use ' instead of ' in the Text definition obviously :)

I couldn't code as well, put myself on a course. Only took me the 8 hours the course was long to learn how to code. Worth it if you're going to do fx.
