There are a variety of ways to use the 24-hour VWAP (Volume-Weighted Average Price) as we teach it. This is a unique tool to Tradesight in the FX arena (although commonly used in stocks and futures). The importance of the VWAP level as it moves throughout the session can never be overstated.
One of the ways to use the tool is to wait for the market to start to get a move and have it bounce once or twice off of the VWAP. Once that happens, you know that the market has addressed the VWAP for the evening and is using it. This happened last night fairly early on the GBPUSD. Keep in mind that these charts are MST time zone, so two hours earlier than EST.
As you can see here, the GBPUSD got two bounces precisely off of the purple VWAP line at point A, just as it was starting to curl up:

From this point forward, each TOUCH of the VWAP can be traded by then buying if the pair trades above the high of the 5-minute bar that touched the VWAP or shorting if the pair trades below the low of the 5-minute bar that touched the VWAP. So, here’s the next touch of the VWAP an hour later, and I’ve drawn black lines at the high and low of that bar:

In this case, it turns up, and the buy point is the black line, but you can see how it played out, running up about 30 pips and stalling at the Value Area Low level:

About an hour later, we roll back to the VWAP and get another “touch” bar, and I’ve marked off the high and low again:

The next move takes out the high of that bar:

And that leads to…another run up just over the highs of the prior push and another winner:

SIX HOURS later, the GBPUSD comes back down to the VWAP and touches it. This charts shows the “touch” bar and then the next bar, which triggers to the short side by moving under the black line:

This leads to about a 25-pip move downward to the LBreak level. Note that we get a 9-bar Seeker setup on that move down against the LBreak red line, which coils the spring for the move back up:

And that move back up looks like this:

Very technical action all night on the GBPUSD despite light ranges.
