There are two types of trade entry. The first is an aggressive entry without confirmation, and the second is a conservative entry with confirmation.
An aggressive entry is made when there is only one area of interest (POI) from which price is most likely to react, or when there are other factors that make this setup highly likely. Typically, such factors are projected liquidity above/below POI, as well as liquidity pools that act as a target for subsequent movement. The advantage is the guarantee of entering a trade in a highly volatile market, when there is a risk of missing a setup while waiting for confirmation. The disadvantages are the increased length of the stop order; experience is required to correctly determine the setup (beginners are recommended to enter without confirmation only by trend).
