Buy and Sell BIDU

Today, BIDU starty rallying in the morning. I missed getting my 260 March Call options at $6.60 yesterday (I should've set it and $6.70 and I would get it). Today, the options rallied to $12 and I didn't get it when I set the price at $6.90. Finally, I decided to buy 10 shares of regular stock of BIDU @ $245 a piece. Later on today when I see it tops off, I sell at $252. It represents 2.85% in 2 hours period. Next time, I should learn how to execute my order faster, I missed a great opportunity for buying options yesterday. O well..
