I have more than 20 years of experience in stocks, futures, etc., and I am currently engaged in FX system trading operations and development. Nice to meet you. In FX, discretionary trading (my own judgment timing) is limited both in time and effort, and mistakes occur frequently, so at an early stage I felt that "systematization is essential for trading" and became an EA developer and SE programmer to practice it. Now I no longer engage in discretionary trading at all and only perform system trading (automatic EA).
