I think this is a great idea. I would love to see some sort of dependency on trades entering. For example trade A enters => Don't Enter Trade C or B or D.

This would be very useful when trying to tune ORB trades into time bands for entry. The problem with doing this as individual ORBs is you potentially end up with 4 ORBS traded rather than one. This is sort of like only trade one contract but across different trades. So something like only trade single trade of this type or ideally a more sophisticated dependency model between trades for entry. I acknowledge it could get complex and/or messy but I would love to see something like that.
