I agree with most of the post, it just seemed like you were saying it's not semantics, that you don't make forecasts, and then straight after, saying you expect every trade to lose. If I've misunderstood that, please clarify. Now that might be a healthier or more practical view to have upon entry, and might stop you being stubborn with losers, but it doesn't change that essentially it's an expectation.
There are lots of things I expect to happen and things I expect to not happen after entry. When things go against my expectation, that's one of the ways I know I should be getting out. Of course I wouldn't expect every trade to be a winner, but if I didn't expect (that word again!) that over a large enough sample these trades would yield a profit overall, then I wouldn't be taking them. And that applies even if you're just taking random entries and profiting from fat tails and a bit of know-how in terms of exits. You have to expect that over the series of trades, a certain property of price will be present at some point that will allow you to profit. If you didn't expect that property/set of circumstances to be there, you wouldn't take any trades at all.
