Poll symbol values on trigger signals.

PollValues(IValueSymbol, TimeSpan)

Polls the symbol as value sequence of object values with a specified period time.

PollValues(IValueSymbol, IObservableUnit, Boolean)

Polls symbol values on trigger signals.

PollValues(IValueSymbol, TimeSpan, Boolean)

Polls the symbol as value sequence of object values with a specified period time.
