Hi,

I am trying to make an VPT indicator https://en.wikipedia.org/wiki/Volume%E2%80%93price_trend. My code works when I start the indicator, but when new ticks come in the value is wrong.
I have a variable "value" I keep adding to. If I keep adding once at every new bar, there would be no problem (That is why when Indi starts it is correct). How do I do this?
The value only may add when a new bar is formed (I need the value of the indicator at the "old" bar. But the indicator calculates at every tick so the value gets too big.

In this case it is preferable to set IndicatorInfo.setRecalculateAll(true) for the indicator. It would make sure that all indicator values are recalculated on each calculate call.
In general it is not advisable or necessary to store indicator state between calculate() calls.
