As said earlier, the occurrence of a morning star pattern is not as frequent as those of a single-candle formation. They are harder to spot, aside from you practically needing to fulfil all four conditions before you can verify its presence.
In this case, we have the AUD/USD daily chart. The price had been trading lower until the point where it created a new short-term low. Prior to this candle, there is a long bearish candle that signals a strong downtrend.
However, the sellers fail to force a close near the session’s low and the price rebounds higher to create a doji candle, which signals the indecision among the buyers and sellers. The next candle is a long bullish candle which forms the morning star pattern. We can now be almost certain that the bullish reversal is about to start taking place.
