For successful system trading, you must:
1 - Have a good system with plenty of historical testing over various market conditions (up, down, sideways, volatile, chop) using realistic commission/slippage (eg. $50/r-t ES contract)
2 - Be adequately funded ... 3 x historical closed trade drawdown
3- Take every trade ... if you don't you will miss the big winner.
4 - Constantly monitor performance ... watch drawdown/profits vs. historical std dev
5 - Have an exit strategy ... when are you going to stop trading the system
6 - Diversification ... two to many low correlated systems.
7 - Realistic expectations ... what do you expect from system
As a bold experiment, I have funded a small account with Man Financial and am currently trading two custom systems (one swing, one daytrade) for the ES via automation.
I will be posting my monthly statements as an experiment show what one can expect.
Attached is a spreadsheet with the equity curves of each system and the combined of both.
I started trading the systems live in 9/30 ... first 4 days were great ...up +2500 plus, currently down -$200.
The combined sysetms have a historical drawdown of around $4k (highest equity peak to lowest equity valley closed trades), so I'm prepared for this.
The hardest thing to get used to is the swing in equity ... I've taken the mindset that this is a business. I've bought a business with capital and that capital is not mine until I sell the business (stop trading the systems).
