Now you're faced with some interesting choices, and these do require a little thought. Not much. But some.
The first RET technically is not an opportunity to enter short since it occurs just a hair inside your support/demand line. But given the undeniable rejection of that resistance level and given that this little RET also represents a failed effort to try again at that higher high, you may just decide to take it, being prepared and more than willing to exit immediately if everything goes wrong and price makes a higher high anyway. And even though the RET occurs on the upside of your line, the entry will be made below it. This approaches rationalization, but it's a legitimate consideration. All of this, of course, takes seconds to consider when you're trading it in real time.
If, on the other hand, you're not that aggressive, you can wait for the next RET. You won't make as much, but it is a bit safer, and perhaps you need that. If even that isn't safe enough, you can choose to wait further, remembering that there may not be another RET and you will have missed the opportunity to be in the short at all (generally speaking, the longer you wait, the more likely you are to be stopped out, assuming you get filled at all).
And now we separate the traders from the hobbyists.
By now you've drawn your supply/resistance line and it gets broken just 5m later. If you took the first RET, you may be intrigued, but if you took the second one, you're underwater and may not be thinking clearly.
But if you can sit tight for a moment, just a moment, you'll see that the first break barely qualifies as one. You may after all have drawn your line -- if you actually drew it -- a bit off. So you wait, and the second bar barely registers. So you wait a bit longer, and though the third bar most definitely is outside your line and appears to be heading north, it can't make a higher high than the bar two previous. So you decide to take the chance, being the proficient price action reader that you are, and continue to wait it out. And it is at that point that price drops back below your supply/resistance line.
Now we have a separate issue. If you waited this long to enter, your chances of being stopped out are that much greater, as mentioned above. In this case, however, you get lucky. Sort of. Because if you enter even a short distance below either of the RETs, you'll be entering at 2812. And unless you're lucky, your fill is going to be terrible. If you enter with the usual stoplimit order, you likely won't get filled at all. If you're crazy enough to enter with a market order, God help you. All of which are more reasons to enter your short as early as possible, in this case no later than the second opportunity ten bars back.
Now. Unless you're plagued with hope, which in areas outside trading is usually a plus but in trading is a curse, you know that parabolic moves not only don't last but also reverse quickly. Even though a supply/resistance line is drawn here, it's superfluous. If you're riding this, you know full well what's happening to you. But if you can set aside the glee for a moment, you can take full advantage of this move and not get stuck dithering about what you ought to do about it, like everybody else.
Once this line is broken, you're out. Even if you wait until the following bar, you still have captured as much of the move as one can reasonably expect.
So now what?
There is a rally, of course, what Wyckoff calls a "technical" rally, meaning that it isn't prompted by mobs of people just desperate to own whatever it is but rather by short-covering. And since short-covering isn't a real "buy", i.e., something that you're going to possess after you've bought it, the rally doesn't last. But, for the time being, you don't know how far it's going to go, so you have to trade it as if it were real, even though it isn't, if that makes sense. If it doesn't, don't think about it for now.
It does last long enough for you to draw a support/demand line, which is broken six minutes later. The routine is to wait for a RET after this break so that you can re-enter your short. However, the short is never triggered because price decides instead to resume its trip north. Technically you shouldn't go long here because your support/demand line was broken. But the short side was rejected. So you decide to go ahead and chance the long anyway.
Unfortunately the long doesn't get very far. How come?
It is an odd but unusually reliable maxim (as opposed to law) that price that can't retrace at least 50% of the immediately preceding rally or decline shows weakness, or strength, depending on the direction. Here, for example, price just barely retraces 50% of the preceding decline. This suggest weakness. And sure enough . . .
But lest this go on too long (too late), let's wrap this up since by now you have at least a general acquaintanceship with the routine.
The long, of course, is exited. Since price made a higher high after the long was initiated, the support/demand line can be "fanned" in order to give a better approximation of where support lies. It doesn't do any good in this case due to the 50% barrier, but it's a habit worth acquiring regardless.
There is no doubt, however, that there is no more support, at least for the time being, and even though the RET is above the line, the short entry, if taken, is below. Again, this may seem like quibbling, but our ducks don't always line up in a nice row, and chances can sometimes be justified.
If taken, the short is exited shortly thereafter and you look for a long entry. Given that there is no RET until price works its way all the way back to the 50% barrier, one could decide to pass. However, there's no way of knowing whether or not price will bust through this level. If it does, you're long while everybody else is scrambling. On the other hand, you can wait for the breakthrough, if it happens, then take the next RET up. Trader's choice.
Whether one takes it or not is of course of no concern to the market, and a short opportunity occurs almost instantly, another case of the RET taking place above the line while the entry takes place below. There is also the matter of price by now having formed a trading range, narrow though it may be. With a trading range, one rarely has the luxury of waiting for RETs because even if they occur they rarely do so until price is nearly at the opposite side of the range, and by that time one has to consider making a U-turn and heading off into the opposite direction.
Therefore, in a case like this, particularly when price meets resistance at exactly the same level, one can justify jumping in at the first sign of rejection and riding price down to the bottom of the range.
Here, though, it pays not to exit too abruptly when the bottom of the range is reached. A long at the bottom would not be triggered if set up as usual, and that signal would prompt the quick-thinking trader to re-enter the short. And if he misses it, there's another opportunity four minutes later.
Price eventually reached 2972 before breaking the supply/resistance line.
