Song Zhiqiang, male, was born in 1970. Undergraduate major, philosophy. In his early years, he worked as a futures broker and engaged in Hang Seng Index futures trading. I once believed in technical analysis and worked hard for it. After graduating from MBA in 2007, I joined a private institution in Shanghai to participate in the training of intraday short-term traders in Shanghai and Shenzhen 300 stock index futures, and had the opportunity to get close to ultra-short-term trading, thus starting an in-depth study of ultra-short-term trading, and then putting forward the idea of "completely giving up technical analysis". After 20 10 Shanghai and Shenzhen 300 stock index futures were officially listed and traded, the author finally had the opportunity to train more than 20 traders according to this idea, thus verifying the idea that "completely giving up technical analysis" can also be profitable.
