BigMike,

I don’t know if you figured out how to set up CD but, if not, you can do what has been suggested above or below are specific steps of one way to do it.
1) Once you have your intraday chart set up you add 2 studies. First add the BidVolume vs. AskVolume study and then click the Settings button. Under the Subgraphs tab
a) for the Draw Style select Ignore for Ask Volume, Bid Volume, and Zero Line.
b) for Difference (SG5) select Bar for Draw Style. Then under Auto-Coloring, select Based on +/- and then just above auto-coloring adjust for the two colors you want. Don’t forget to check Show under Value Label to display the number.
This will plot the delta for each bar. If you don’t want this and just want CD then just select Ignore under Draw Style for Difference(SG5)

2) Then add Cumulative Sum of Study and again click Settings. Under the Settings and Inputs tab, change SG1 to SG5 under Input Value.
Then under the Subgraphs tab you will see only Sum(SG1) and do the same changes as for Difference in 2b.

remember to put dll in /data folder

things to look for
- overlay study adds data source to its name to prevent the confusion in case you use multiple overlay studies.
- I point to chart #11 but you may have to change it to a diff number in case it doesn't do it automatically.

There are two charts required for the final study. There is a chart with a very short timeframe per bar, 1 second, and then another chart with a timeframe that the bars are displayed on.

On the 1 second chart, there is the BidVolume versus AskVolume study. This allows us to have access to the BidVolume and AskVolume over a very short timeframe per bar for the next the studies used. It is not recommended to set this chart to 1 Tick because that generally is less CPU efficient.

On the 1 second chart, there is the study Cumulative Sum of Study that performs a summation of the AskVolume from the beginning of the trading day. This summation is reset at the start of each trading day. To disable this reset functionality open the Study Settings window for the Cumulative Sum of Study and set the Reset at Session Start Time (Reset at Start of Trading Day) Input to No.

On the 1 second chart, there is a second study Cumulative Sum of Study that performs a summation of the BidVolume from the beginning of the trading day. This summation is reset at the start of each trading day. To disable this reset functionality open the Study Settings window for the Cumulative Sum of Study and set the Reset at Session Start Time (Reset at Start of Trading Day) Input to No.

On the 1 second chart, there is the study Difference-Study Subgraph which simply calculates the difference between the cumulative AskVolume in the cumulative BidVolume by referencing two prior studies.

The next step is to create longer duration bars of the 1 second cumulative difference. On the 5 minute chart we use the study Study Overlay-OHLC which references the Difference-Study Subgraph study from the 1 second chart and creates Candlestick bars. That is it.

Using the Chartbook

To use this chartbook select File >> Open Chartbook and select the chartbook named: Cumulative_AskVolume_BidVolume_Difference_Bars.cht. If you do not see a chartbook with this exact name, then please install the latest prerelease of Sierra Chart. This chartbook also will be overwritten every time you upgrade Sierra Chart. Therefore, if you want to save changes to it, then use Save As on the File menu and give it a different name.

You will see two charts open. One chart will have a very short timeframe per bar (1 second by default). And the other chart will have a longer timeframe per bar (such as 5 minutes per bar). The symbol of the charts in the chartbook will likely be old or not matching to the symbols used by the data or trading service you are using, and will need to be updated. To update them go to one of the charts and select Chart >> Chart Settings. Enter the current/correct symbol in the Symbol box. Press OK. The other chart will automatically update to the same symbol as well because there is a link (Chart Linking) established between them.

If you have set the Cumulative Sum of Study studies to not reset at the start of the trading day, then you will want to go to the chart with the very short timeframe bars and set the Days to Load setting in Chart >> Chart Settings to the number of days that you want the Difference Bars based on.

If you wish to use these charts in one of your existing chartbooks, then you will need to duplicate both charts into another chartbook. To do this use Chart >> Duplicate Chart to Chartbook on each of the charts.
After you duplicate the charts to another chartbook, you will need to go to the longer timeframe per bar chart which contains the Study Overlay-OHLC study and set the Chart Number input for that study to reference the shorter timeframe per bar chart. You need to look at what the chart number (#) is of the shorter timeframe per bar chart and select that one from the list.

Missing Data: If you are missing any data in the chart for the day or missing bid volume and ask volume, then the Last value for the last bar in the chart may not be accurate. You may want to refresh the data following the instructions in help topic 7.1.

So I made progress using the last method (it looks harder than it really is). But this method is resetting the CD on each session it would seem (see attachment) whereas @ sctrader's method was not reset on each session. I am a novice at CD, but I know @ FulcrumTrader doesn't reset his daily.

I checked both charts (primary 6 range + 1 second CD) and they both have 00:00:00 to 23:59:59 session times, I couldn't figure out where/why it is resetting the values for the study on a new session.

Awesome, thanks guys.

I am still having a small issue. There is still some gap in the CD data, see panel 2. I tried changing the source chart from 1 second to 1 tick, it made no difference. These gaps are infrequent, but present. And it screws up the moving average because when there is a gap the value of '0' is used on the moving average, which then subsequently also screws up the panel scale.

Why am I seeing these gaps in CD data?

I've added the MA because I was just trying to duplicate @FulcrumTrader's chart and that is what exposed the issue.

from SC support looks like if you have no data with that time stamp they just leave it blank.
