Yes, this is a huge part of what I do, playing ES and NQ off of eachother.2. You need to look at both the ES and NQ charts for structure. That's because they vary a bit in their structure so that there may be a setup in one that you don't see in the other. The key to this notion is that when the market sees support on any index chart, THEY BUY EVERYTHING... not in the same magnitude, of course.
Both of these points are excellent, but the devil really is in the details. Clearly you aren't going to give away the details, but honestly, with trading, everything actually works. Since no trade is going to be an 80% winner, heck, 60% seems to be a healthy and realistic number, this means that 40% of the time, the trade ends in a loss, and that loss means that someone can take the opposite trade and turn that into a winner. This means that a setup which for you might look like a breakout, someone else will treat it like a fade. To make it work, the details of where to get in and exactly where to get out, for either a profit or a loss, is really what makes trader profitable. And none of this is unfortunately very KISS friendly.3. The notion about "not chasing breakouts" is waaaaay wrong. All big moves involve breakouts and you need to be on the right side of them. Deal with false breakouts as they occur.
4. Price TA is all about "recognizing setups". That's all you get. You can't know how long the play will last or how far it will go. You have to play everything after the setup "by ear". If a setup ends up being a 5 point move, fails even before that, or goes for 50... you don't get to know that in advance.
I was going to post another chart with a very fast chart at some of the key areas you suggest would be trades, but since its all hindsight, it might not matter much.
But I do wonder if you can comment on some metrics. You mention things that make sense like:
You short resistance. If it fails and breaks out, you stop your short and go long. It's not "either/or", it's "both".
and also:
Your objective is to "catch some of the good stuff" and putting up with the fizzlers is part of the price for trying
So what to you is a healthy stop in terms of points? What is a realistic win rate?
Bottom line... If you had taken every setup I market, exactly as market... and any others that you thought might work that didn't (and stopped when they failed), you'd have made a bundle.
It just so happens that with a bit of volatility, there were some good moves, but if you end up taking stops on failed breakouts, or trying to go long at double bottoms that break, and then maybe lose twice in a row by trying to first short resistance and then get on board with the breakout, which also fails, then you're likely not going to have a good day.
If you're gonna tell me that half of your trades end in losses, then using a Monte Carlos simulation, I can see how having 5 or 6 losers in a row is expected, and hence shouldn't be feared, but as I'm suggesting, adding metrics to any talk about trading price action is absolutely necessary.
For example, using your methodology, and taking every trade as you should, and using a 5 point stop, and knowing you might get 5 losers in a row, if you tell me some days you are down 25 or 30 points, when your average gain on an average day is only about the same amount, then this makes sense. But seeing as how often these setups fail, it makes a person want to dig deeper, and then of course try to cherry pick trades, hence skip them, which clearly doesn't work since we never know what will happen. So you have to take them all as you suggest, and be prepared to lose 5 or 6 times right out of the gate. Would you say this is realistic?
