trade 4h and daily (or other timeframes) same time?

is it okay to do this, since trades can be correlated? i'm thinking it's alright to e.g. trade a daily setup and a 4h setup at the same time (none have reached break even yet). even if it's the same currency. of course if we trade setups on the same timeframe than it's a different story.

do what ever you want to do. Why not in the same tf?

i mean if trades are correlated, DON'T trade them on the same timeframe (e.g. two 4h setups that are corelated, that is twice the risk). but i could take one 4h trade and another daily trade, even if currencies are highly correlated right? the initial stop losses would be at different levels so it's not doubling up on risk, it seems to me
