correct. wave 3 has such condition to meet. but your logic got problem. After you see an enitre 5 wave, then you can identify which one is wave 3 by using such requirement. but you can't just assume it is wave 3 first , then conlude that it will go 50. that all depends whether it is wave 3 or not.
You have more experience so thank you for the tips, as traders we are playing the probability game, I see its probably a wave 3, as such I think its too risky to short against the trend, we saw how quickly price moved from 27 dollars to 41, looks at the moment to be a bull flag. I Try and trade 3rd waves and 5 waves only (if i can keep disciplined), as these are are lowest risk , particularly 5th waves.., where 3rd waves as you rightly pointed out are sometimes false dawns.
