Alright so I'm a little drunk and I rarely trade options.
At the start of the video they are looking at the apple's chart and it's showing an ascending triangle pattern forming. Usually in a pattern like that (relating this to currency trading which is what I do) when price breaks through the resistance up top the price will continue going up.
Essentially the options strategy they are doing is called a Ratio Call. It's when you're holding a stock (for long) and you want to leverage yourself against that stock buy putting out an options contract.
Using the example the video shows:
If you buy at $25 at 380 (stock price) and you sell 2 strikes at $27 at the stock price of $410 then if the stock rises in price (like it appears that it will in the previous triangle). If the stock price jumps to $420 then you will have to provide 200 shares to the buyer at $410 while you get 100 shares for $380.
Hope that explains a bit.
Also you got pm.
