Error in intraday mode

Technical Help
#1

I have a problem when going from EOD data to 15 min bars. I've setup two DB's with the same symbols, only difference being the resolution (bonus info: they contain tickers from different timezones).

When running on the EOD database the backtest completes successfully. When the same code is run on the 15 min database it breaks with the following error:

HTTPError: ('500 Server Error: INTERNAL SERVER ERROR for url: http://houston/moonshot/backtests.csv?strategies=vix&start_date=2018-01-01', {'status': 'error', 'msg': 'Length of names must match number of levels in MultiIndex.'})

Any help?

Intraday data has an extra "Time" level in the index: Usage Guide

At minimum, to go from EOD to intraday data you'll need to use .xs to extract a particular time of day from the intraday data. See Usage Guide
