Positive Ending to the First Half of 2018

• Yesterday after the market close the Fed Stress Test results came in favorably for almost all banks. Thankfully when the banks are up, Amazon and Google go up too and I trade Alphabet (GOOGL) options primarily.
• Alphabet was poised to open $6 higher than yesterday's close. So I watched it go up and then come down in the first 10 minutes which showed me that it was going up to start the day so I jumped in buying 5 Call options with 1137.50 strike price. It quickly ran up to 1141 where it stalled. I was quick on the trigger after missing on $500 yesterday and sold for a max profit. See illustrations below:
  
• From selling my Call options at the top, Alphabet slipped down and came back, but didn't make a new high. That is where I bought a Put option. Unfortunately I sold it too soon as I made another $125, where if I had more conviction I would have held it a bit longer for a $400 profit.
• There is no guarantee with anything. I just try to make money based on momentum opportunities I see in the market with specific stocks. The option prices in Friday are the lowest due to the limited time they are good, but the opportunity to make a profit diminishes without momentum that is carried through the day. 
• Learning Lesson:  Never submit a Sell to Close at Market Price before the market opens at 9:30am. I bought back an out of the money call option on Best Buy with a strike price of 77 with the expectation that I could close the position out for under $10 because it closed on Wednesday for .06. When I looked at the transaction details I bought it back for $41 yesterday at market open. Best Buy ended the week below $75 and this option would have expired today worthless which would have saved me $41. I bought it back yesterday because Best Buy is a retail stock that moves with FANG many times and FANG was so low Wednesday that it was going up on Thursday. I expected Best Buy might have the possibility of going above 77 by the end of the week and I didn't want to chance it if I could close the position for under $10. MY BAD!
