For me, the best tf for executing trades, but one needs to watch bigger tf as Chuchu mentioned, also this depends on what you expect from the trade you are in,,I think when you master 1min tf, you can see continuation /reversal/everything gets a clearer picture. My main chart looks like this for a long time now, not migrate from it , we`ll see what the future brings ... Emas 20/50/100/200/1440, bb, etc just for an overview, but I think my main system is not the most important thing, it is also the entry and exit technique that needs to be mastered
