If we are looking at a 3rd wave, then technically they should always make it to 1.618 x the length of wave 1. This is where your targets are different, I start the measurement from the low of wave 2.
So with KNB, wave 1 was 1.2c to 4.1c = 2.9c. Wave 3 starting at 2.6c give us the first target at: 2.6c + 1.618x2.9c = 7.3c.
Going forward I'm going to trial selling half at the 1.618 level, and trail a 35 day lowest low as a stop. This should get just under the 100% depending on the buy level, I have a 3.8 buy on KNB, so I'll sell half at ~92% gain and trail the rest. The 35 lowest low will start moving up quickly in May, so it's got plenty of breathing room currently. ~30% initial stop.
Interesting tid bit, the 35LL jumps up to catch up to the 65ema at the swing lows!
