I would like to introduce a kind of social platform that allows traders to share their thoughts and ideas like share the idea/information on Facebook. It is a social platform for traders(stock, bitcoin, coin, fx, etc). It also provides a lot of useful function and tools to analysis and trade the stock/coin/etc..
TRADING VIEW

This trading view gives you a glimpse of the other analyst's perspective and allows you to share your analysis of each other's events.
