lets you chart for free multiple binance pairs. up to 150 on a page.. charts are from tradingview, customizabie. and you can add your favourite indicators
you need some decent ram on your pc to open many charts.. initial loading takes a while but once open charts work fine..
I've tried it and you're right, it really needs ram that is compatible with websites that open a lot of charts in the window. actually this is very helpful because we do not need to open one by one to see one coin to another coin. but with the current state of my computer, it is very long waiting to open one by one.
