Rolling (Margin): EWZ December 17th 25 Short Put to January 21st... for a .32/contract credit.
Comments: Rolling here at greater than 50% max for a realized gain and a credit while keeping buying power effect essentially the same, since I'm rolling this "as is" (i.e., from the December 25 strike to the January 25 strike). I originally collected .58 in credit/contract (See Post Below), so have collected a total of .90 ($90)/contract with this roll relative to a current short put value of .57, so have locked in .37 ($37) of realized gains so far. 30-day implied is still pretty decent at 41.3%; otherwise, I'd probably just leave it alone running into expiry.
