1. Without ranges, there's no place to start unless you're entering a reversal off the upper or lower limits of a trend channel, which is itself a range; a diagonal range.
2. You will NEVER allow price to hit your stop. The purpose of such a stop beyond the problem of losing connectivity is to force you to focus on what price is doing without regard for your trade. Once you've entered the trade, you cannot think about it any more. Turn off every little button and flashing light that tells you how much money you've made or lost. Focus ONLY on what price is doing. If you don't like what price is doing, get out. Whether you're still in the plus column or the minus column doesn't matter. Focus on price, not on your trade.
3. When you're just beginning to gather data, then of course you will misread the tells and exit when you shouldn't have. However, if you're not thinking about the money, you will be in a far better position to evaluate this new situation, and if price doesn't for example drop the way you thought it would, then, yes, a re-entry is certainly possible.
In any case, you have something to start with. Ideally, you would go through an observation period of at least a couple of weeks in order to learn to see differently. But there's nothing I can do to force you to do so. If you must cut right to the chase, then begin testing your thesis on actual hindsight charts. There are plenty to get you started in the Foresight thread. There are more in my journals. Your thesis may blow up after one trial. Or it may hold for thirty. But eventually you're going to have to make adjustments. This does NOT mean that you have to start over. But you will at least have something that is yours, that belongs to you, that you can have confidence in, not something that somebody told you to do, something that will evaporate as soon as the going gets rough.
The very worst-case scenario? 5 points is a hundred bucks. So what?
