SP:SPX   S&P 500 Index
The first candle completely below the blue channel happens to be a hammer...

If the hammer is confirmed, it could be enough to take price to the top of the brown channel.

If the hammer is invalidated, next target could be the middle of the brown channel.

Note: the color of the hammer's body is incorrect, as the closing price is greater than the opening price. It happens in other candles too.
