Three black crows. Depending on your colors these might be three red crows. Very simple and reliable candlestick pattern.

You have the first candlestick closing lower than the open, giving you your first indication that the previous bullish trend may be losing strength.

The next day we gap up from the close of the first candlestick, but we fail to make any headway, and close lower than the open.

The third candlestick does the same thing, gaps up from the previous close and once again closes lower than the open, and lower than the previous close.
