support asynchronous events

HI,

Normally in bots you have triggers and filters that if meet will trigger the open position but is general this are synchronous ,

my question is about having an open position when in a specific timespan 2 or more events .

in this example a trade should be opened when event 1 the cross is true ,  event 2 the relative chikou span (yellow  line) is below candles and event 3 the candle breakout the cloud.

as you can see in this case the cross happen first , after some candles happen the event 2 and lastly the event 3 (well here at the candle close )
