This pattern is a sequence of three Doji. The occurrence of this pattern is extremely rare so when it occurs it should not be ignored.
1. The market is characterized by a prevailing downtrend.
2. Three consecutive Doji are seen. 3. The second day gaps below the first and the third.
Pattern Requirements and Flexibility
The Bullish Three Star consists of three consecutive Doji in which the second Doji gaps below the other two Doji. It is sufficient that the gap is a body gap. There is no need for a gap between shadows.
Bullish Tri Star requires that we have a market which was in a downtrend for a long time. However the weakening trend is probably indicated by the bodies that are becoming smaller. The first doji is a matter of concern. The second Doji clearly indicates that market is losing its direction. Finally the third doji warns that the downtrend is over. This pattern indicates too much indecision leading to the reversal of positions.
Buy/Stop Loss Levels
The confirmation level is defined as the last close. Prices should cross above this level for confirmation. The stop loss level is defined as the lower of the last two lows. Following the BUY if prices go down instead of going up and close or make two consecutive daily lows below the stop loss level while no bearish pattern is detected then the stop loss is triggered.
