I am using the lean engine on Mono/Linux and so far it is working fine with the example files and data.

I have added new csv files with daily data into Data/equity/usa/daily as zip files with the same structure as in the spy.zip (spy.csv) file.

When the engine tries to do load the data I get "Failed to load subscription TNA" eg.

Is it not enough to have daily data or how does it work?

My algorithm only uses Resolution.Daily.
