Last Friday, I made a nice long trade which I posted here in real-time (including my error in exiting the trade too early). I subsequently received several PMs from ES Journal readers asking me to explain my methodology, and specifically how I arrived at my profit targets.
My methodology is embarassingly simple and unsophisticated. I'm sure it could be vastly improved -- especially after studying some of the S/R zone charts that Apex82 has posted here on a regular basis. (Anyone heard from him lately?)
Just to catalyze a discussion, let me summarize my admittedly over-simplistic approach. Then you more-experienced traders can improve on it and perhaps we'll all benefit.
First, some terminology:
The most basic price action in any auction market is a three-wave move -- either up-down-up or down-up-down -- that I will denote by its four price points A, B, C, and D. In an up-move, the price goes up from A to B, down from B to C, and then up from C to D. (In a down-move, the directions are reversed.)
For an up-move, B>A, C<B, and D>C. For a down-move, the inequalities are reversed.
Now here's the most over-simplistic assumption in my model: In a three-wave move, the most likely price movement for the third wave is equal to the price movement of the first wave. In other words, AB = CD.
Now, we all know that this doesn't always hold true. Sometimes CD is only 50% or 60% of AB. Other times, CD is 130% of AB. But the most likely value for CD is approximately equal to AB. (At least that's the assumption I use when setting price targets.)
Okay, now let me try to relate what was going through my head last Friday as I was trying to decide whether to trade, and if so, when to enter and whether to go long or short...
First of all, my trading objective is to hit home runs, not scalps, so I generally prefer to trade with the trend rather than countertrend. To figure out what the trend was Friday, I looked at the 60-minute chart to review what had been going on for the past 2-3 weeks. When I did that, it seemed clear that the trend was up.

NOTE: The green crosshatched rectangle depicts information I did not have when doing this analysis prior to Friday's trading.
It doesn't take a rocket scientist to see that the short-term trend changed (rather violently) from down to up on August 17th. (More about longer-term trends later.)
