Being programmer does not mean that you can think analytically. Actually programming is the easy part. About PA, all the things you might call PA can be separated and tested separately for non-random effects after separation. You don't have to have ...

No more BS - What have you learned?

as I said, it's possible to make money by "feeling the market" but how can you really know how well your method really works if you can't test it? This is exactly the reason why there is so much psychological BS on every book and forum - it's ...

No more BS - What have you learned?

Basically yes. Not necessarily executed but it must be testable by mechanical method. I'm not saying that some people can't make a lots of money only by "feeling the market" but what I claim is that every one of their methods can be systemized as ...

No more BS - What have you learned?

Here is another non bs comment: Anything that can not be systemized and tested is not an edge. If the rules are not clear, they don't offer anything but endless speculation. Only once the rules are clear and defined, you can tell if the result has a ...

Why observe indirectly if you can observe directly? Sorry for being vague. I just think you have to think a bit further what you really want from your results.

IMHO Gp/ga works simply because evolution works but it's damn hard to get it working correctly so that it doesn't overfit the results (ie. finding good fitness algo is crucial and very hard). About my systems, it actually doesn't matter what kind of ...

That's a good way of doing things and I definitely will think about using this kind of solution in the future when I'll update to the next version.

Maybe I was a bit unclear, I don't think exit is non-important but for me [or to my genetic algos by the way] at least it's much easier to find good exits when the entry is good than vice versa. Therefore for me personally a good entry is much more ...

No more BS - What have you learned?

I don't believe either version is good enough so sorry I cannot answer this (*. My point is that by selecting the entry at some point you also select the territory you expose your exit system to. I personally couldn't randomize either if I would ...

In the example above are assuming that at some point price does go speedily into positive territory. If you know this happens then you definitely have not selected a random point, you have selected a point where this happens more than not. The exit ...

No more BS - What have you learned?

They might be but they might actually be quite similar I haven't said it here but I have also experimented with different kinds of "blending" methods (involving trade-level correlation checks etc). In the end, however at least for me and for my ...

I think the main question to ask yourself is what kind of attributes you want your [combined] profit curve to have. When you know what you are looking for, you want to have a formula that generates one number that quantifies all those aspects. Sorry ...
