Yes, that's why I asking here.
I need to open at least 8 charts, multicoin chart can open a lot chart but the problem is a 1-minute time frame while my activity needs at least 30 second time frame for more accurate prediction. I read the premium plan, to open at least 8 charts you need the highest membership costs around 60$ ~XD.
I guess just like @mk4 say, most service or third marketplace clumped up TradingView only available with 1-minute time frame cause for "second" list time frame only can be accessed by premium membership.
BTW, Thx everyone who already answer my question.
