Every time this violation occurs, it sends tremors through my thinking as it relates to my model. When I think I have solved it, the model becomes considerably more accurate. I have no idea how or what I am missing,
What defines an uptick? The market red? The price at the bid? It is sound advice, I am just curious what your definition is.Quote from Maverick74:
Nitro I don't trade fundamentals or CNBC news stories. If I did I would have been short from 800 and higher in the S&P. I trade price action. I think we are due for a 5% pullback here shortly but why not wait for the market to show weakness? Why get short on the uptick?
Allow myself to be wrong? My model spews out a number. The difference between it and SPX is either in a range or it isn't. If it is, I stay neutral. If it isn't, I act. There is no room for "allowing" anything. As soon as I introduce what you are suggesting, unless I misunderstand your intent, I have introduced subjectivity into my methods.... Allow yourself the opportunity to be wrong and often. Do this and I believe you will make leaps and bounds in your progress of perfecting your trading system.

I'll define an uptick as a daily bar that closes on the high. It's more of a broad assertion though of just saying that you are selling into a strong uptrend.

I'm not suggesting for you to be subjective in interpreting your model. I'm saying to be open to the idea that your model might indeed be wrong. Or perhaps more appropriately said, your model may be "off".
Now, it is certainly possible to say, well, this model has run off the rails. Of course I do that! Where I think you and I disagree is whether it is possible at all or not, or even if it is, in the approach I am taking to automated systems. I do not disagree with that, but that is a whole another huge subject.
Nitro, all I'm saying is you lean on your model the same way some lean on God or the government or my husband is only beating me because he loves me so much. Your model is just that, a model. We all have our "models" in life. For some it's code of ethics, it's how we live our lives. For some, their "model" is how they lift weights in the gym. For others their model is something they use to trade with. In any case, a model is only as good as the man that made it. And that man is fallible. All men are fallible. I'm simply asking you to accept the fact that the problem with the model "could" be the guy who is programming it. That is usually the case with all of us Nitro.

I think part of the problem is that I assume people have a scientific background, and therefore things like "model" and what we mean by it require no exposition. From dictionary.com

Obviously I mean 1,2,9, and 10. It is a simplification by definition! Of course it could be wrong. The goal of a model isn't to say, this _IS_ the market, or this _IS_ the way the proton works, it is to say, this is the way the proton works to some degree of accuracy.
As soon as a counter example to your predictions occur, you have to go back and rethink your theory. This is all elementary science, and the way by which all knowledge progresses, at least by the scientific method!
