I dunno, I am still waiting for a tips/clarification.
This problem really bothers me
Marco Montemari: some example:
In both cases you use the passed arrays, and buffers, without setting as-series or not.
To determine the indexing direction of time[], open[], high[], low[], close[], tick_volume[], volume[] and spread[], call
ArrayGetAsSeries(). In order not to depend on default values, you should unconditionally call the ArraySetAsSeries() function for
those arrays, which are expected to work with.

So you mean using ArraySetAsSeries will solve my problem...Ok I will try.

Hi guys,
sometime I need to change TF to show the indicator.
It seems it does not load or laod partially.
Should I preload in On init function or what?
I am struggling with this issue. Any tips?
