There are two issues that you need to address; First, defining the s/r levels that are significant, and second, defining the conditions that would prompt action, i.e. what does price have to do to make you place a trade.
As for S/R, I use the previous day's high, the previous day's low, the opening price (RTH),
chart swing high, chart swing low, and the previous day's close (RTH).
If those levels make sense to you, the second issue is what does price have to do if it reaches yesterday's high from below, to make you sell it is long, short it, or buy it to establish a long?
Price can only do one of three things: It can continue (breakout), reverse, or go sideways. This is where the work of developing a trading plan really begins. What kind of trader are you? You mention that you have a plan that allows your to maximize profits during trends and minimize losses during consolidations. What is wrong with that plan? Now use those levels as areas where if your current method gives a sell, then sell, or if a buy, then buy.
If you are a day trader the only s/r levels you need are those I listed. You will do yourself a favor if in addition to those you pay attention to the midpoints of ranges and swings.
Ok, so given what you suggested I have identified RTH PDL as my closest R level. This coincides by a couple of ticks with the whole movement 50%. I will pay special attention to this level when reached. And post my update at the end of the day.
