there are some good sites for market analysis, coinigy is also nice, but this site only provides 30 day trial, next will be requested an upgrade, next there is tradeview, the site is very popular among traders, I also use it, for the free version can only use a maximum of 3 indicators, but for me that's more than enough for market analysis.
Hey , thanks for the info!
We want to hook up free charts to our backend service and feed the data into charts ourselves ... we have our own format . So basically we are looking for javascript / HTML5 code without service or data integrated but very rich as in bitfinex, BitMex and with free license , so we could put it on our website , it does not matter if we have to display license as long as it's free. I will look into tradeview as it's the most suggested by all users here.
