I'm trying to get started with the platform, but I'm having a hard time navigating the docs.

I'm trying to get minute values for all securities available.

IEnumerable<Slice> history = History(TimeSpan.FromDays(EndDate.Subtract(StartDate).Days), Resolution.Daily);

is logging 0, how can I achieve this. I was expecting to start receiving value in my OnData method.

Many thanks
