Hello Dukascopy Team,

I would like to report two issues with PERSBBANDS indicator.

One issue is observable on Time Aggregation feed, the other on Renko Feed. Both issues are reproducible with attached strategy.

Time Aggregation feed issue:
The strategy calculates 4 last values of the indicator on each data feed (onFeedData() method). However only the newest values corresponds to what I see on the chart, the remaining 3 nether match values on chart nor previously calculated values.

Is this is a bug or am I calculating the indicator wrongly or is there other explanation? How to make previous values of the indicator matching chart values? Worth noting - the same strategy works as expected when using SMA indicator.

Renko feed issue:

This is the same strategy but using 3-pips Renko feed. In this case none of the values matches chart values, which is worse the previous example.

How to make current and previous values of the indicator matching chart values? As above, using SMA indicator does not reveal any issues. However what is more in case of Renko - indicator calculation is one brick behind the chart. How to make indicator calculation to be up to date?

Thank you and best regards,
kurak
