Possible short.

Now, there is no one strategy that is the "holy grail of strategies". However, with certain practices you have a higher rate of profitability.

• 1. Notice the trend "down trend, in this case"
  2. Identify key area/areas.
  3. Define target/s and stop area.
  4. Wait for confirmations of your biases.
  

This chart for me personally i'll be trading on a retest and fail should it follow though with failing at key levels, or previous lower high level.

NB, I purposely didn't put in risk to reward ratios or targets. But you should get the idea.
