Functions on a Multidimensional array?

Hello,

I'm trying to work on a script dealing with hedging and would like to keep a relation between an order and it's hedge order. I thought a multidimensional array would be ideal for this: for example, HedgeRelations[25][1] would give me the ticket numbers for the 26th order and the one hedge order associated with it. (This would help me to track multiple orders that are hedged).

However, I don't know how to calculate the size of the array (there will only be 1 hedge per order, but there could be numerous orders hedged) or how to resize the array - do those functions (ArraySize() and ArrayResize()) only work for single dimension arrays?

Any work arounds. I was starting to setup a routine that would put the order and it's hedge in a string like "ticket#-hedgeticket#" and store in a single array, then work to split and search these to manage them as needed - but thought a multidimensional array might be more efficient.

Any thoughts? Thanks!

I had the same issue about two years back, and the solution is simpler then what you have presented.

For both of your orders, use a unique 'comment'
and later scan all orders, match ordercomment to your unique string and you have a way to manage both hedged orders.

OrderSend("EURUSD",OP_BUY,1,Ask,3,Ask-25*Point,Ask+25*Point,"EURUSD Hedge",16384,0,Green);

OrderSend("USDCHF",OP_BUY,1,Ask,3,Ask-25*Point,Ask+25*Point,"USDCHF Hedge",16384,0,Green);

So when these two orders are opened, you will have two orders that have unique comments. If you scan all live trades and find "EURUSD Hedge" and "USDCHF Hedge", you can manage the hedge.



Above is one solution, the other solution is to use magicnumbers.


Hope this helps!!!

Thanks!
