Hi db please excuse my lack of knowledge as ive just recently started trading but have been following this thread with great interest, looking at the chart you posted now that the price has retraced back down to the SR level what would one be looking for to get confirmation of direction a break below the 1700 level which would then fall in the next SR level, what confuses me is how far down on this chart would one wait before entering short.
Justin Mamis in The Nature of Risk talks about three kinds of risk: price risk, information risk, and time risk. Setting aside time risk for the time being, one assumes a greater degree of information risk when he enters a trade before knowing everything there is to know about the context, that is, he gets a great price but is flying without a net (or at best a net with very large holes). He assumes a greater price risk when he waits until he knows everything about the context before taking action, that is, the more confirmations he waits for, the worse the price available to him.
So, how long you want to wait and how many confirmations you require will dictate how much of each type of risk you assume. If you wait for multiple confirmations, you will not likely get the best price. If you want the best price, you're going to have to step out there on that highwire.
In this case, using this weekly chart, one might enter when R is hit two weeks ago. If he entered at R, he'd still be in profit. If he waited for a break of the bottom of that bar, he'd be at breakeven, if he were still in the trade. If he's not yet in the trade, he may wait for a break of 1700. Or he may wait after that break for a retracement back up to 1700, if there is one (there may not be, which takes us back to information risk and price risk).
If you're trading this via the QQQ, you have the luxury of dipping your toe into the water rather than jump all at once into the deep end. You can buy a few shares on a break, buy a few more on a retracement, buy even more on a continuation, or dump them all if the whole thing turns out to be a fakeout and reversal, all with little or no capital risk. The important thing is to anticipate every contingency and come up with a plan of action for each of those contingencies. That way, no matter what happens, you know exactly what you're going to do, how you're going to do it, when you're going to do it. This preparation enables you to remain calm and make a rational, objective decision when a decision is required.
