Used Tim's strategy using puts, as taught by Mark Croock. This was a test. ECYT was bound to go down this week or the next one. It was cheaper to hold and less risky. I bought 5 puts at the market open. When I saw it wasn't spiking (where I wanted to buy 5 more) but going down, I bought 5 more, which is what I could afford. I didn't have to be precise in my entry. It was harder to squeeze me than shorting. A swing is easier to take. I took the meat of the move to see how selling puts works.
