if the bottom of the crash was the end of wave 1, then the third impulse/wave would end at 37.3k

the retracement of wave 4 reflects off of 0.5 retracement perfectly (for both impulse 3 & wave 1+3) when taking the crash as the bottom of wave 3, it may be worth referring to this as wave 3 instead of the truncated 5th as suggested
