Post From: Limit order Fills on Replay

Good morning.

I'm testing some strategies on CL futures market using the attached orders from the order window and a strategy coded in ACSIL. What I'm finding is limit orders are frequently getting filled at prices not possible/probable in the real market. Limit orders getting a few and sometimes more ticks of price improvements. For example:

I am long CL futures 1 contract, on the attached orders screen I set it up for a bracket order of 8 tick target and 8 tick stop. I often get filled for 10 tick profits. In the real market, my limit order would get taken at the 8 ticks. I've traded manually for years and don't think I've ever had a price improvement on a limit order in a liquid market like crude.

Is there a setting to force a fill at the target limit price instead of allowing price improvement?

edit: I'm using the Accurate back testing system replay method of testing. I have also messed around with the "update chart internal" setting. I've tried 100 plus I've also tried down to 50. I have a fast machine with and i7 6 core CPU and fast SSD drive, 16 GB memory if any of that is helpful.
