timeline alignment between traders?

[arthur19q3]

It seems that I am unable to align the timelines of independently running traders: I initially intended to monitor a futures contract trader, and when certain conditions are met, send trading commands to the corresponding options contract trader (in another independent thread). However, since the engine is event-driven, traders trade based on their independently held timelines of data and derived market events under the control of their respective strategies. Any insights in terms of timeline alignment between traders?
