MBT - Trailing Stop Behavior Resulting in Multiple Commissions

[LeeMellinger]

I just started trading with MBT today and noticed some odd behavior with an ATM Trailing Stop with one block of 2000 shares. When the stop executed to close full position the shares were sold in smaller orders at the broker/exchange and NT appears to have added the ATM Trailing Stop to every order resulting in multiple commissions (one for each order). Does this have something to do with simulation?

Hello,

The commission are simulated based off the local NT settings and are tied per execution event. In the case you receive a partial fill which results in multiple executions, you will see the commissions reflected for each execution. This is a limitation of the simulated commissions and improving this behavior is on our development team's list of future enhancements.

Set your commissions directive properly to "per share" and no minimum.

I'm referring to actual commissions charged by the broker. Meaning, the literal charges accessed by the broker (real money). Not simulated. Appears to only be triggered by an ATM trailing stop with MBT. IB did not do this. I suspect simulated OCO logic, though I'm not certain. I'm still investigating.

Hello LeeMellinger,

Orders can execute in partial executions. NinjaTrader does not have any effect on the execution of orders - orders execute as per market dynamics. I am not sure how commissions are setup as per your MBTrading account. However it seems to calculate commissions for each partial trade instead of one commission for the entire trade. I suggest to contact MBTrading for clarification regarding the commission structure of your account.

Hm. I believe this is what you asked: "Does this have something to do with simulation?" Simulation does not come into real money trading. That is why I did not realize what you meant. My apologies.

You're correct. After doing some checking MBT is not charging for each partial fill. However, the main issue was that a trailing stop loss was apparently attached to each partial fill and I'm still checking to see if these trailing stop losses will trigger separate charges since they are really separate orders on MBT. I sent in the log from yesterday to support. I'll get back to you on the trailing stop loss issue.
