Buuufff, difficult to identify them... This kind of impulsive wave looks more common on cryptos than in traditional markets... Minor coins seem to behave more often with extended 5th wave than more established Coins as BTC or ETH... Other big coins but with less entity, for the moment, as STELLAR and RIPPLE seems to work more often with longer 5th waves...
as usual, if you identify a 3rd wave not extended (similar or slightly longer than the 1st you could bet for an extended 5th, placing sell orders higher and buying again at the level of the 61.8% retracement of the 5th wave...
Nevertheless, with ''explosive'' or pumped coins this logic may not fit at all.
Did I answer you properly?
Cheers
