There's about a dozen different methods to play these pivots all dependent upon your trading goals. If, for example, you're looking to pick up a couple of quick pips you can wait for price to close above (or below) the trend line. When a bar closes outside the lines jump in at the market with a 3-4 pip target.
Another is to wait for a trend to be established. The confirmation of a trend varies from trader to trader, but whatever your method you must first determine a trend. Then it's simply a matter of waiting for a pullback to a pivot point to enter in the direction of a trend. Some might wait for price to equal the previous pivot while others might enter when price comes within 2-3 pips of the previous pivot. Regardless of your rules, you play the most recent pivot as if it were support or resistance.
Still another method is to track the formation of the previous 3 pivots, which includes the last 3 highs and the last 3 lows. You look for certain patterns to form and then break outs from the pattern. A little screen time combined with some back testing makes these patterns apparent.
I have my own personal favorite setup that I like to use that has proven consistent over time. But each trader is different and has their own trading style so doing a little homework can yield great results and everyone can roll their own. It's just important to know there's great value in studying these pivots and dividends await those with a careful eye.
