I think you will just miss some ticks but you don't get every tick especially in times with high (tick-) volumes.
no they get overwritten so please see
OnTimer()

I am working in an Expert Advisor which makes heavy calculations in the OnTick() event which can take seconds and I am wondering what happens with OnTick() events that are triggered while the current OnTick() event is being handled.
I do not mind "loosing" OnTick() events but I am concerned about them making some kind of queue, as if that where the case then my Expert Advisor will get stuck handling old OnTick() events that have been queued up.
