For BTO it calculates using the ASK instead of the BID, for STO it calculates using the BID instead of the ASK. Intended?

I do not believe that you are right. The way C2 calculates open position P/L is to determine the profit or loss if the position were closed at the market.  
  
  
  
Thus, if you are long, you would need to sell your position, and so we use the **bid**. If you are short, you would need to buy back your position, and thus we use the **ask**. If you can point to any specific instances where this rule is not being followed, I’d be interested in knowing.  
  
  
  
Do keep in mind (as I pointed out to another user earlier this morning) that we can’t use _real-time_ prices when displaying positions (since we don’t pay the exchanges in order to do so) but we do use real-time prices internally.

I very well could be wrong. It may be because of the delay that I thought it was doing the opposite. 🙂
