Jul 17 Options Writing Trades Update

The benchmark Nikkei gained 127.15 points to 12,887.95 for its biggest one-day percentage gain since 1 month ago, but trade was thin as the market waited for more U.S. bank results later this week, including Citigroup on Friday. I wrote the N225 Oct 15500 Call options for 20 pts. I am eyeing the N225 Oct 9500 & 9750 Puts to add to Oct's positions on volatility.
