Sorry about the wait. I have been extremely busy trying to get parts of my software completed. This afternoon I went ahead and threw something together.
Download dll
here
Place in your SierraChart folder
Open up a new chart and set it to 1 tick
Change it so it only loads 1 day
Go to Chart Studies
Click "Add Custom Study"
Choose "Bid/Ask Volume"
At the current time it does not calculate all previous bars (fill in historical data graphically). This could create significant load time (not sure). However if it's really wanted I could add it. On the first bar created after being added, it WILL go back and calculate the correct and current count though. Also, since it goes off the current bar historical display will be erased if chart is refreshed.
Now, like I said, I just threw this together. I am NOT guaranteeing that everything is working EXACTLY as expected. I did set the three intervals to 3M 15M and 60M and it seemed to match up to the same numbers given when you use Sierras indicator on those time frames.
Please let me know if bugs/problems or any other features or requests.
