Short Simulated Order Fills on Wrong Side Of Book

[Generic]

Instrument: EURJPY
Context: Market Replay using simulated orders
Trade: Sell 1 EURJPY @ market (150.3) Stop Ticks 250, Target Ticks 600
Description: Trade entered successfully. The target was met at 149.7 using the bid price rather than the ask price.

I've included part of my log, the NT log and the output window. First up is my log which shows a sell entered using the bid price. To close the position the ask price should be used but for some reason it appears the NT uses the bid price. NB: Longs work correctly

This could happen. Our simulation engine for FX will simulate limit order fills once the market trades at the limit price. In FX, we subsitute the bid price for the last traded price. The last trade price is used for determining if a price level should be filled. The only time this is not true is when connected to GAIN capital where the ASK price exclusively used for filling buy limit orders.
