I am aware of his twitter following and influence in Japan. I'm wondering if anyone knows of other similar solo traders with a large following and a good reputation.
CIS is a price action trend follower who disregard fundamentals. He said so himself that earlier in his life he followed fundamentals and loss. Thus changed to trend following and never looked back.
Most following CIS not for his trading but because of his gamer as you're probably already aware because you stated you're aware of his twitter following. Also, look into stocktwits. wrbtrader
