Fully automated trading is very hard for consistency.
If the people with bags of money can't crack it, then odds are neither will you or anyone else.
You are correct to focus on YOU, as all your problems start and end there.
Half the battle is being in the right place at the right time.
Yes. Odds are stacked against everyone including those that are successful. That said, someone will win. People with bags of money and the willingness to crack it do crack it. That said, the find it and automate it part is not hard for me but finding a system that produces results I can trust/tolerate
has been hard.
In my experience, many systems, markets and timeframes are required to achieve something that can compete with good discretionary trading (smooth equity curve, high risk adjusted return, small tail risk).
People with the funds to diversify effectively across asset classes/exchanges/markets/strategies/timeframes etc. have an advantage and likely have a team and have also accepted that many different types of work and skills are required to pull off automated trading.
It's not something most individuals are willing or able to do alone.
Virtually every system I have created has gone through extended periods of terrible performance. The ones I have run have shown periods of good enough performance to be worth the risk until they weren't. Inefficiencies that make for high Sharpe approaches don't last. Some of the robust stuff that does last, like long term trend following requires users to endure very long periods of deep drawdown and the feeling that "maybe this time it's finally broken"...
I'm in the short term, does not last forever and might never work again camp. I accept this. The biggest impediment and challenge is how to recognize it's over without giving back all of the profits. I have a crude approach to this but I have not yet developed a satisfactory and effective way to systematically turn systems on/off according to their performance.
So, rather than expecting that that I'll develop a perfect set of systems and a system for managing them, I use system development as a way to stay in tune with current market regime/tendencies and to develop a framework and set of reference points or expectations about different methods. I may end up with something I have willingness to run and automate but that's not my primary objective.
I find my discretionary trading is much better when I am testing ideas and monitoring systems concurrently.
I am not looking for a holy grail or trading advice. I have confidence in my trading skills and abilities. Sometimes I am very happy with my trading results and behavior. I'm working on understanding where my outlier behaviors and risk taking come from because I can trace 80% of my aggregate $ losses and associated drama to a very small small number of bad and un-planned trades .
I plan to continue chipping away at my limitations and issues and think that posting here, sharing ideas and results and receiving feedback will bring up my issues and help me to work on them.
I appreciate the feedback.
