I ask because I heard an interview with Linda Raschke where she said she didn't know any such traders. I thought that was pretty significant as she is a very successful trader herself.
I have tried quite hard over the years to automate some winning trading rules, but with no success in the long term.
I am not asking anyone to reveal any secrets, I'm just interested to know if it is possible.
I’ve heard Linda say the similar thing, i.e.; that she doesn’t know any trader making money with fully automate system. However, when she and other discretionary traders say this, they don’t mean that it’s impossible to make money that way, but rather that the money made from automated system trading is not worth it in comparison to discretionary trading. (by discretionary I don’t mean shooting from the hip, but pattern recognition which cannot be done by computers)
Most automated systems struggle to make >20R per year on consistent bases if they want to keep drawdowns to less than 10%.
Through position sizing one can jack up the returns from automated trading, but then the drawdowns become too large for most people to handle. (even with multiple systems)
In one of the podcasts Linda says that if she goes through a bad patch, she apparently goes to automated or semi-automated trading for a while to get her confidence back.
Tom Basso (market wizard) uses fully automated system, and he trades futures markets for diversification purposes. But his returns are low in comparison to discretionary traders.
I'm not a fan of automated systems, but it's doable provided you settle for low returns and high drawdowns. It is all relative, and depends on one’s objective and expectation.
What works well is having computer to scan for certain backtested criteria, and then use certain amount of discretion as an overlay, (provided that the trader's discretion is better than if left alone to the computer)
