How to find total number of symbols traded.

eg. I am trading buy and sell GBPUSD, EURUSD, EURJPY and USDJPY

and I want this to return total of 4 pairs traded. Anyone know?

 
at least from reading your post once, I have no idea what you mean, sorry. Please elaborate.
 
From the orderstotal, I only want to extract 4 pairs from the example above. It should only count the number of pairs only.
 

maybe this (or your mods make it 'this') - gives u launch point anyway...

edit.1: silly me! forgot check if trade or pending... hey! great mistake - maybe u can put in the 1 extra line or maybe 2 ;), in .... the function ;)

hint: OrderType()

good luck...
