Feeding Strategy Portfolio/Exposed values

E.g. I did it to receive the 1 min. candles inside the strategy also, so you can simply setup multi candlesize strategies without the need to change your e.g. existing 60 min. strategy and candlebatch everything manually.

I do want to keep strategies small and lean, which is why they can't access all events. But yes, 1min candles can be handy. See this PR as well: https://github.com/askmike/gekko/pull/2468
