The lines that go up and down from the candles on the chart are called shadows (or wicks). They show the price range in which trading occurred over a certain period, but ultimately the closing price of the candle ended up within its body.
The upper shadow (or wick) indicates the maximum price for the period.
The lower shadow shows the minimum price for the same period.
If the upper shadow is long, it may indicate that there was high demand during trading, but ultimately the price decreased. If the lower shadow is long, it may suggest that there was strong demand during trading, but the price still could not rise above a certain level.
Shadows can help traders analyze market sentiment and price behavior at specific moments in time.
