Quote from AAAintheBeltway:
If you are making money consistently trading futures, why try stocks?
That said, if you are interested in systems building and testing, there is a wealth of info available now. I think one of the most valuable uses of these backtesting platforms is to demonstrate to you that most of the indicator based approaches you read about in various books are worthless. Backtesting is also very helpful in teaching one about the effect of stops and their placement.
In many ways I think it is easier to design a system for futures because there are only a few markets versus thousands of stocks. Stock systems basically have to become scanning systems to select stocks on the move. See the various Jack Hershey threads, particularly the one by spydertrader for examples. With a commodity, you can focus on one tradeable and come up with entry and exit criteria.
At the moment I am not interseted in trading stocks. But in the future that may change. My concern was to figure out how to go about designing a system to trade futures/commodities.
I would like to figure out how to have the system pick out the trades for me. I am sure that will take a lot of trial and error, but thats fine. I also like your comments about backtesting being helpful in figuring out stops. I will probably spend quite a bit of time doing that.
Right now I keep it pretty simple. The majority of my trades would probably be considered trendfollowing. Hey, if it works, and its simple, why try to complicate it?
For instance I was short OJ for about 6 months. Pretty boring, but it kept making money. Then it started feeling weird so I got out. Then I felt it was going to turn around, but since I had no verification I just bought a bunch of calls, just in case I was wrong. That was about 3 weeks before the first hurricane hit. The options are working out fine.
When I first got into OJ I could look at the chart from across the room and see that it was obviously in a downtrend. When I got out it just felt weird. I have no idea how I could translate that into a programming code. I think the big downtrend I could program (maybe) and then issue buys or sells based on that, but I have not spent any time trying to figure out the "feeling".
I have gotten a lot of good feedback so far. I think my next step is to sign on with Tradestation or some other platform, and start playing with it.
I have been kicking around a few trading ideas and until I came across backtesting I really could not try them out without putting money on the line or spending tons of time papertrading. (I am a huge believer in papertrading). One of the ideas is so simple, I can't see how it cannot work. I only say that because many people discard anything simple as ineffective, so theres a good chance nobody is using it.
