I was looking at the USO October put option that are out of the money.
Is it me or does the \*5s' and 0s' option priced slightly differently.
\*5's = 105, 95 , 85 ...
0s' = 110, 100, 90, 80
Back in the day 70's and 80's, in equities, Traders would tell you never park your stop losses at the 0'hs' ( .00 or .50 ) and 1/4's .25 and .75 ... because it was a common place used by the public
Is my observation in options something of the similar sort, where the public finds it easy to choose and the trading houses price it differently to generate more activity?
