The Bollinger Bands % is useful to spot reversals and/or the beginning of a new trend. The VWAP %, built on the same principle, tends to be more reactive. It can be used as a tool to take partial profit, exit, or prepare to enter a position on a reversal. It can also be used on MTF. For example, you plot it on H4 chart and M15 chart. When the VWAP% is above its Signal line on the H4, then each time on the M15 you have the VWAP% crossing over its Signal you enter Long and exit at the crossing under.
