Hey guys,

This may be a very silly question, but suppose I have 4 trades open, they will have Position 0, 1, 2 and 3 on the MODE_TRADES pool..

Now, if I close the order that's assigned to position 2, will I be left with positions 0, 1 and 3, or will the order in position 3 be reassigned to position 2?

Yes I guess so.
Simply do a test by closing 2, then check if it closes 2 positions.

Any pool, at any time, have indexes form 0 to MAX-1 !
... where MAX can be : OrdersHistoryTotal() or OrdersTotal() .
Any trade operation change both pools (list of orders) immediately.
WARNING : Before new OrderSelect() , you still have old data selected (loaded in memory) !!!

So, If you have 4 active position ( list index =0,1,2,3 ),
and close position ( index=2 ),
the result is :
-> Total position = 3
-> possible List index = 0,1,2

So here is a test :
- if you have 4 positions, and close position=2, try :
--> OrderSelect(3,SELECT_BY_POS,=MODE_TRADES ); ==> return ERROR
--> OrderSelect(2,SELECT_BY_POS,=MODE_TRADES ); ==> return current position=2, previous=3
Small GAIN, big WIN

I quite frankly don't know why you would do something like that.

If you use a loop, as in:

for (i= 0 ;i< OrdersTotal(),i++){

if (whatever is true){
close or whatever;
break;
}
}

Have your parameters for closing as if statements, you just go through the list regardless of where the position is, and close when you get to the trade you want to close, then break out of the loop.

Another method would be to store the trade number you want to close and then go through the list with the method above till your trade numbers match. Both are much better ways of doing it than trying to work out where the trades positions is in a list.

Yet another method is to comment your trade when you open it, then use the method above to go through the list and look for the comment.
