Yeah, running flats are uncommon. Though, Cryptos are not the same as equities so can't exactly overlay the equity personality over the cryptos.

I for instance find expanded flats to be very common in cryptos...eg. the btc correction now.

Also, cryptos traits:
Fifth waves on daily degree are often extended

Hurry Up and Wait syndrome

Phasic/Non Phasic of Alts to Mother BTC

Rare for truncated fifths in cryptos

etc etc
