If there are N bars between previous high and later high, take profit at the close of N(th)/2 bar after the later high; of course assume you haven't been stopped out.
ES (10/07) example:
There are 24 bars between the 2 highs; if enter short from the later high area when the price was broken below the low of previous high (1073.25), and exit at the close of the 12th bar after the later high. That's 1042.75.
