Investopedia explains 'Tri-Star'
A single Doji candlestick is an infrequent occurrence that is used by traders to suggest market indecision. Having a series of three consecutive doji candles is extremely rare, but when it is discovered, the severe market indecision generally leads to a sharp reversal of the given trend. The "three stars" pattern can also be used to signal the reversal of downward momentum when the pattern is formed at the end of a prolonged downtrend.
