its a great tool to scan underlying s and put things into context. Just gotta use common sense. 50 IV percentile on BIDU isnt the same as 50 IV percentile on SPY :D
etfs are amazing because of the limited downside
so $1000 = $10,000 in leverage and u can only lose $1000 that's better than any options contract i know of
if you got a $3k account that $30k buying power interest free doesnt get better than that
