Gulf Support-based Buy with High winning-chance strategy

The support is at the old low, 157. I saw the stock was moving down fast with low volume. I jumped in at 157 and 156.5. The risk-reward was OK but I felt like I would have a high winning chance of buying it here. The profit-making price is the next resistance,161. This should work out.
