today a new epic tool, the "Fair Value Gap (FVG) Finder".
Fair Value Gaps are quite important to trade, as they represent both volume and trading unfilled gaps, which most of the time are filled and then price reverse. This indicator will let you set alerts on when a new FVG is found and when it is filled.
Traded together with Breaker Blocks (BB) and Supply/Demand Order Blocks (OB), you can easily spot important points where to start a short or a long trade.
