Anyone know what thier network looks like? Can't they afford the best? What a disaster, somebody better get fired for this.

Wow, Mr. Hershey, you are obviously very sophisticated, wise and experienced. I won't attempt to understand all that you've explained here in this thread. Perhaps this would be an interesting topic all it's own? I would like to focus this thread on wether or not a mechanical system that...

I have included the TradeStation workspace I am trading from, for those of you who use it. You will need to change the extension back from .txt to .tsw

I am trading from California, so maybe this accounts for the discrepancy?

I realize that 5-10K is possibly too small an account to trade this system. But, is a backtested system feasible in real life? Are backtested systems purely opportunistic? Those who say it can't be done, have you tried it and failed? I don't mean to be smug, I am very direct and purposeful.

Good point. Most of the systems I've come up with short more aggressively than long. Is this because of market trend or maybe markets fall faster than they rise?

If anyone wants some documentation, please just ask. I have covered what I think to be my bases. But your objective opinions are why I am here ;-) I use Tradestation, so give me some time to clean up the report. Default report is huge. EliteThink I realize that many different strategies...

Yes, it is optimized. I started with 6-month back to present. Then took out the top few trades by narrowing down the optimization range. Increased to 1 year back, re-optimized, etc. ANd again at 2 years back. How would one "test the sensitivity of the MA lengths and entry bar parameters?"

I'm not trying to be sarcastic. I seriously have no idea what you are talking about. Must have been absent from class that day. ;-) I appreciate you patience with me, but can't offer any answers until I understand this further. regarding the "precede" signals, I tried to clarify that I meant...

Thanks gms that was enlightening. Mechanical trading is definitely not full-proof and without it's own set of obstacles. You comments are appreciated!

This is correct. different criteria for long/short positions.

Since I am correcting my previous posts, let me make one more:

Hopefuly this is what you refer to. I do appologize for any confusion this may have caused. Maybe I shouldn't be trying to write this at 2:45 in the morning ;-) I'll start with this and elaborate as needed. System: es daily data (no after hours to throw off charts) 30 minute bars Long...

If this succeeds or fails, I would hope to lean why. Maybe those of you with superior trading skills and experience would help us understand these dynamics better? Your thoughts and consideration are appreciated.

Again, Why do you say this, can you offer a suggestion? Maybe you have some experience you can share with us?

Why do you think this? I don't want to argue, I want to make progress. And yes I did a backtest in TradeStation. That's how I came up with it. I'll post the EL script if you like. I purposely picked a simple, average (in my opinion) system. My goal, again, is to show if an average mechanical...

Good observation, this systems assumes no trade level risk management. Either you risk the money or you don't. I don't want to grow a portfolio, but rather generate income. I know that many will take issue with this, but 1% is just WAY to conservative for me. I'd rather stick to a day job...
