That addresses partial fills vs. ticket charges. I don't know if MBT charges for cancels/modifys, which is a different issue. Also, it does not address the pacing/MM restrictions, which are exchange rules. My point is that a strategy like trying to sit on the bid and offer, making markets along with the MMs, is not only unlawful, but would cost a fortune in cancel/modify fees unless you get a ton of action. AFAIK.
Thanks for the good points. I'm trying simply to translate my existing strategy into using options with automation.
My straegy should be comparatively very simple and basic. Also I don't expect MBT would be the only broker for automated trading options. At least a start.
