Merge of equal and opposite "hedged" positions, without commission, to flat.

Merge of equal and opposite "hedged" positions, without commission, to flat within the same symbol currency pair. I understand that some broker cTrader implementations use a "net position" approach (MB Trading, I believe), and others use the more typical "deal" or individual entry "position" approach. In the latter, each "position" must be closed, which costs commission. Within an instrument Long 1 and Short 1 is equivalent to flat, and Dukascopy implements a MERGE operation which closes those positions with no commission (as it is accounting only). Please consider implementing this.
