<i>"Still not getting it..but that is OK. I disagree with aspects of your beliefs. BTW, Roger is testing a wide range of time frames for each instrument..so far so good with 89 tick up to 15 and 30 minute at similar 1:1 trade management."</i>
Here's what we aren't getting. Performance is posted inside several threads for automated (mechanical) "otto" system trading per ER and ES. On its face, what is presented by verbiage and pictures makes it appear that working systems are in latter stages of development.
So far, so good.
We also read where said systems will be offered to clients, to the public, thru broker arrangements, some way or another. Right?
For that to happen, the system writers need to pick a timeframe of charts and trade them with real money. That creates the system track record. Whether it's 89 tick, 3min, 15min... no one cares. Pick the parameters, enjoy positive results <b> and then offer those parameters to the public</b>.
Following me? Good :>)
If several systems are created using varied time frames, long-term results may average out roughly the same. But, like tossing three quarters at once, individual results will vary thru the distribution curve.
A 3min system may be hot one week, whereas 15min may lag. That creates client issues you would then learn about soon enough.
So, if it's to be a purely automated affair, someone has to assign black & white rules to the process. That includes specific time frame, entry - exit - stop management rules.
If there is more than one timeframe, you then have multiple "sister" systems.
In any event, I do wish the best in this process. It's all just speculation until real money is traded for a minimum of three months, six would be better. Until then it's amusing speculation... nothing replaces real-money results.
