Hi all,
I am trying to have my stragety to run on two resolution, second and daily. Went to some of the good posts from Michael, but I am unfortunately stuck on
- Cannot find ResolveConsolidator lib
- Or if I am using the right indicator for quandl data
- And levergage with EMA (add and udpate EMA)

I guessed that I could not attach backtest with the runtime error
