Really simple set up, training your eye to spot these patterns in my opinion is essential for developing consistency with your trades. After seeing the reversal, which using the 1H and especially 4H makes these easier to spot. You can see where the left shoulder has formed, aligning with the right shoulder on the 61.8 level. Other than that, we notice the area was not only previous support, but resistance. This liquidity indicates an interest for movement around this level. The rest is all price action and patience.
