Such a pattern is essentially made up of 3 doji candles with the middle doji day being more shooting star. The psychology behind the pattern goes along the lines that the market has probably been in an uptrend or downtrend for a long time.
Obviously in this case an uptrend. With the trend starting to show weakness bodies are becoming smaller.
- The first Doji would cause concern.
- The second would indicate little direction left in the market
- The third doji would put the nail in the coffin of this trend.
