Topic: What Timeframes are needed to upload?

I am working with "EA Studio" and useing the Timeframe H1.
Until now i only uploaded historical data for exact this one Timeframe:
- to create Strategy Pools for my Symbol.
- to create EAs out of my Pools.

But is that correct?

Today i found the Button "Academy" and there was written, that i always have to upload all Timeframes ...
Now i am struggling.

What is correct?
1. Create Strategy-Pools and EAs on H1 only with H1 historical data.

2. Create Strategy-Pools and EAs on H1 with historical data from M1 to H1.

3. Create Strategy-Pools and EAs on H1 with ALL Timeframes.

Re: What Timeframes are needed to upload?

If you work only with H1, then there's no need to focus on other timeframes.
