Look at the chart.
If a red candlestick with an upper shadow appears on it, it is possible that there will be a reversal of the trend and a growth in the price of the asset.
The strongest signal of an increase is the appearance of a red candlestick with a small body and two long shadows.
If a green candlestick with a lower shadow appears after this, it’s another signal confirming he reversal of a trend.
