Best practice - Calling Update() on publicly exposed properties

[Shansen]

Referencing Update() (https://ninjatrader.com/support/help...t8/?update.htm) and bltdavid (https://ninjatrader.com/support/foru...34#post1089734), calling Update() inside the getter of a publicly visible Series ensures all Indicator values are up to date.

What is best practice when an Indicator may have two dozen publicly visible Series?

Should Update() be called inside the getter of all publicly visible Series, given Update() will not do anything where there is no bars data waiting to be processed by the indicator?
Alternatively, does Update() come with a performance impact? Should Update() only be called on one (strategic) publicly visible Series?

Hi Shansen, thanks for your question.

NinjaTrader will update your guest indicator automatically. Update() is typically used when a strategy is running OnEachTick and the programmer needs to ensure the guest indicator has called its OnBarUpdate method and updates its properties for the same tick.

If Update() is not included in one of the public properties then NinjaTrader will call OnBarUpdate only when a new data point is received. So If you do need to add Update() to all of the get methods then its fine to do so. Performance is always something to consider when running OnEachTick. If the code written is lagging the system because its running OnEachTick then the code would need to be optimized, but in most cases performance should be fine.

Please let me know if I can assist any further.
