Expanding the analysis, this is what I'm looking at in TWTR right now. We're already in the long, and adding a bit more next week. It's possible that TWTR confirms a weekly 'Time at Mode' uptrend signal, which would propel it (probably due to acquisition talks again) to the target on chart. The cue is when we see price hit 20.01 during this week, probably after earnings, or some news regarding bids.
I'd reccomend either buying calls out of the money, or selling puts at the money, or trading bull call spreads, or owning stock, but be careful with the amount you buy (risk is $3,21 per share bought, stop losses aren't viable). You can buy puts to protect your downside here, or short calls once we go higher from here as well, but not for now.
