 The bookmarked volume dots display the transactions that have taken place on the best bid and offer. The green dots are aggressive market buy orders that have transacted on the best offer. The red dots are aggressive sell orders transacted on the best bid. Let's zoom in and use the data tip tool for details. I'll make the volume dots a little bit bigger here by the slider on the toolbar. Let's hover over this green dot here and you can see the fourth line of text gives us the volume information. This dot is for volume of 2. This red dot over here is for a volume of 211. Therefore the size and the color of the dot display the type of trade and its relative volume. Sometimes the volume is displayed as a pie chart to give the overall delta of the volume that has taken place. Let's continue to zoom in here. And you can see that bookmap has broken apart all of those transactions that make up that volume delta. We can continue to zoom in here and see all the details that have exactly unfolded. We are down at microsecond level. We can continue to zoom in if needed but you can see that the trades counter is showing eight transactions that have taken place here for a total volume of 25. Let's zoom out again and you can see we've aggregated the volume back into a larger green dot that shows a volume of 25. Now let's right click on the volume dots here and bring up the volume dot settings. You can display the dots as 2D dots or 3D bubbles. You can play with the size of the dots that you want displayed here, the transparency, and then in clustering there are different settings here to cluster the volume in specific ways. You can have it by none, smart which is a combination of basically time and volume and you can play with the slider here to make the clustering influence bigger or smaller. You can display it by time, by every minute here, or second, or hour, or by volume, and input an amount of volume you want here to be displayed per each dot. You can also inherit your volume dot settings from your bars or you can apply them to the bars as well. There are some filtering options down below here with minimum displayed volume. If you bump up the number here you will display an aggregate view of each dot. With the minimum trade size filter you will display each transaction for the precise amount that you input here. For more information about the volume dot settings go up to bookmap help and user guide here and this will bring up the bookmap user guide on our online wiki.
