Hi nix, don’t get concerned with multiple time frame analysis, each time frame is independant of one another and has their own levels etc so if trading a daily chart we don’t even need to be thinking about what’s happening on the weekly.
Your are correct in saying signals on the weekly are more powerful as there is more information contained in the signal, I would say in that situation if a tradable opportunity presents itself then just trade what you consider to be the better setup.
Also I will just say if you are taking multiple setups where one of the pairs is the same (ie in your case a eur/gbp trade and gbp/chf trade) don’t put all your eggs in one basket!
