Holidays in Japan

Today is my first day back from a holiday in Japan, and I wanted to make a bit of extra cash ($1500) to cover the money I spent overseas. I wrote 10 put contracts on BHP with a 20th July expiry date. I got the same premium as my earlier trade - $1.50, even though the strike is lower because this one has more time value.

The contract size is back to the normal 100 shares per option, so I'll be fine to let this one get exercised if the price drops, effectively giving me a $40.15 purchase price. Here's the price action over the last few months. The strike price is the horizontal line right at the bottom, so that looks pretty good to me right now! I just have to wait until the 20th July to see what will happen.
