need this to happen in aapl.. this parabolic run ,drop to lower nip ,retest upper nip,drop again to recent lower nip,fail to hold then drop to next nip is the simple strategy used,doesn't always hold/work but that's the repeated pattern seen over and over,opposite for the runups,using aapl for an example ,it's not a mean reversion stock like the spx but the picture is a simple way to illustrate it...once you are in you can use the shorter timeframe nips.cleave.ledges to adjust ,massage your avg,taking profits /losses to keep you in the trade
