Graphing open interest for Futures Contracts

[Tigger]

I have a question about Open Interest. I've added the Open Interest study to my daily chart, but my study displays bars in groups of three for Tue/Wed/Thur, in other words just 3 bars per week. And during a shortened holiday week it only shows 2 bars.

Is this normal? I'm not sure if there's an issue with my data feed, or if it's something with Motivewave.

Does anyone else graph open interest on a daily chart?

I didn't know we had such a study. I tried it out now. I am getting the same results on all futures, just 3 bars a week. However if you look back before July (on all instruments), there were 4 bars per week, with some periods even having a bar every day. It does not make sense to me. OI is reported daily on the CME. My data provider is CQG, however I think the data for this study comes from motive wave themselves (similar to the historical data on a continuous contract).

Thank for checking that out, so it's not just me. My data provider is Rithmic.
