If I understand everything correctly, multitimeframe-trading forward or backward should be made from bottom-up.
How will zorro handle this:
I run a backtest in the 1 minute timeframe and fetch the ATR-value of the 60 minute timeframe, will I get the value from the actual 1 hour candle or from the past 1 hour candle?

If yes, then function run in tick makes really no sense
