These are useful charts if you want to pick an entry/exit as the price nears or crosses over the VWAP, or you may want to take a position when the LTP has deviated from the VWAP
To use this Advanced Chart click the LTP with VWAP.blc file below to download it to your computer, then in the top left corner of your screen click
Settings > Edit Settings > Charts > Advanced Charts
Then in the lower left corner of your Advanced Charts window click 'Import'
The second advanced chart is similar to the first but will display the back/lay prices and Volume Weighted Average Price (VWAP) as line charts for each selection, the charts are displaying the 60 data points and is plotting a new data point every 5 seconds as shown in the image below
To use this Advanced Chart click the Back_Lay Price with VWAP Chart.blc file below to download it to your computer, then in the top left corner of your screen click
Settings > Edit Settings > Charts > Advanced Charts
Then in the lower left corner of your Advanced Charts window click 'Import'
To display the information on this Advanced Chart you will also need to download and import the following rules file into Guardian, once downloaded to your computer open Guardian and on the ‘Automation’ tab click ‘Import a Rules’ file.
Then each day just add your markets to Guardian and apply that rules file to them all. The rules file will then store the required data from the markets and pass that to the chart file.
in most instances my friend! 
that fires when the VWAP is crossed? From the servants maybe? An added indication.
