Cheese, I am upset that a theory I had about the market is completely wrong. I take each hunch that I have, backtest it, with as little expectation of its results as possible.
When the result fails, the logical step would be to discard it and move on.
But, the issue I have is that there is no denying that the system counters my original thoughts.... If this is the case, and it turns profitable with a simple changing of my code to reverse buys and sells, then neglecting to go down this path seems like throwing away a good idea.
It is good to see other members of the forum (Hypo) can validate he has tryed this before with positive results.
I think that the real question to this forum I have started is about theories we form on the market, and how valid they really are.
For example, a system created for the sole purpose of trading a "hunch", and that hunch being proven wrong.... well if its wrong, what is right? The reverse seems to be based on the data I have availble. Problem is, I cannot explain why the reverse is true! Therefore, is anyone elses system they trade (mechanical) make complete sense (can any system developer look at a chart and say "Here, this is why price does this at this point?")
