Custom Instrument not matching data loaded with same resolution

Hello,

I am trying to use CustomInstrument using examples posted in this forum and I am probably missing something because CustomInstrument output does not match data loaded for the same resolution.

I have 1 minute resolution for an instrument and created indicator with CustomInstrument using 15 minutes compression (same instrument than 1 minute chart).

When plotting the indicator I have the following issues:

1. It duplicates the same candle 15 times for each 15 min interval
2. It does not match the data loaded for the same resolution & same instrument

I am attaching a screenshot of the issue, could you please assist with this?
Thanks

Hello DrissB,

It would be very helpful if you could attach the exported Indicator you're testing in PLN format and the workspace where the issue is reproduced (you can save it through File > Save Workspace as).

Alternatively, you can send these files to our email support@multicharts.com for further analysis.
