But there is no swing down. You have an upward movement and within this movement a bullish pinbar appears. But there isn't really a swing downwards, the move ist straight up. In my opinion, fo a swing down you would need a really visible move downwards, than finding support and turning back upward. A single pinbar isn't a swing, it's just a wild pinbar. It may be a swing on a lower timeframe but for this chart, it isn't.
a swing would create an obvious zig zag pattern. Your chart forms a straight line, no zig zag.
