Does code always complete?

 
Hello all,

During heavy times of trading... does code that executes at each tick ALWAYS complete prior to the next tick, or can the next tick interupt the execution of the the previous ticks code? Are there any settings that can gurantee code completes (disregarding the next tick trigger?)

What are the rules concerning this?

Thank you,
