# Playground: registerSymbolTicks()
Adds a set of ticks to a symbol in the engine dataset. Multiple ticks can be added to the same symbol, ticks are internally ordered by date.
Ticks are triggered when the local date of the engine becomes greater or equal
to the tick date. Time is elapsed through elapseTime()
or elapseMeaningfulTime()
.
