there're a lot of site that give you a place to draw a charts for free.
like Bitcoinwisdom.com but it's not really good for trader in there, because it's not in detail only a line and a curvy thing.
You can use trandingview too:
http://Https://www.tradingview.com/There you can customize your graphics and use various tools for graphical analysis as well as share your ideas.
This site is extraordinary, you have the paid version, but the free version supplies well the needs for trade. The graphical tool is in some exchangers too.
what are you talking about ?
it is free,i used this many times for drawing a chart before(have been 3 months not in there,so i might be wrong if they're right now charging for it).
indeed that is the best place for us to draw a chart,and in there also we can share our thought plus we can talk to other people about our chart and speculation in the chat boxes.
the best thing is,you can draw a chart in detail in there.
other than cryptocurrency,in there you can also see forex and other assets
