Feb 13 Option Trades Update

I am looking to write N225 May call options this period. I am looking at the 16500-17000 levels. If the Nikkei goes up strong tommorrow, it will be tommorrow. On the other hand, it may be range bound as the market wait to see the outcome of the 2 days BOJ meeting starting tommorrow. Key GDP data will also be out tommorrow & may affect the markets reaction too. US retail sales data for last month was just out & reported an unexpected increase & might provide some support for the Nikkei too. Lets see.
