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..
The site will certainly be useful. But, I think having only Binance pairs and not finding the pair we want is the lack of site. For example, it would be more useful, if BTC/ETH graph of all exchanges had been instead of just Binance pairs. So, it would be useful to compare the same pairs in separate exchanges. On the other hand, site needs the option of choosing the pairs. Someone who wants to choose the 5 pairs he wants, will have great difficulties.
I think not all traders open charts up to hundreds of pages. Because it's usually hard to find focus when too many charts are opened. Only need to open a few to be analyzed. Does not also require a computer with high specifications.
IMO having more options is not an obstacle to us. If 5 of them are needed, use that much.
