Position Size

 

My Question is .... If I put on a Trade with a Position Size of " 2 " (Volume in "New Order Window") .... and the Trade is executed, is there anyway to

Scale Out of Half of that Trade ( Sell " 1 " ) and allow the other Half ( "1" ) to ride .... without having to sell out the Whole " 2 " and enter another Trade of " 1 " and incur addition Spread Commissions ?????

Reason:
