 Bookment has the option to display the last traded volume with two aggregate numbers. The white number here is displaying the total aggregate volume that has taken place here at this price level of $22.55 and ¾. The red number here in parentheses displays the last traded volume here that took place on the best bid. These were aggressive market sell orders for six contracts and therefore it is red because it is market sell volume. I'm using the move tool here and we'll scroll back and demo how this actually works. So last traded volume here was aggregate of nine total and all of those nine contracts were here on the best offer. As I scroll forward we see more trades or more volume that has traded here on the best offer and we're showing the aggregate. All of the volume here has traded on the best offer with aggressive market buy orders. Ninety-five contracts total and ninety-five of them were aggressive market buy orders. However, note that we see a shift here in the best bid offer. We are still trading at the same price level of twenty-two fifty-five and three-quarters. But as I scroll forward we see the distinction here. Now we are trading on the best bid. The best offer is a tick higher. We're still trading at the same price level. So we see ninety-five contracts here that have traded and all of those traded on the best offer and then as I scroll forward we see that three now have traded here on the best bid and these are aggressive market sell orders and that number is now displayed here in the aggregate view for the red number in parentheses. That has refreshed and is now displaying three but the overall number that was ninety-five previously is now showing ninety-eight. So it is aggregating all of these trades that have taken place here at this price level. Now if the price level changes and if I zoom out a little bit we can see that everything is traded still here at this same price level and we see the complete aggregate here in the white number. Okay, a hundred and fourteen contracts and nineteen of those were last traded here on the best offer and then you can see the distinction here. Now we have refreshed and we have traded at a new price level up to twenty-two fifty-six. So we see that the last traded volume up here was for seven contracts and we have the aggregate for seven here aggressive market buy orders on the best offer. In this case both numbers here have refreshed and the aggregate counters begin again. This has been a highly requested feature by professional traders for some time now they can understand areas of potential exhaustion absorption and trap volume by comparing the last traded volume here with the overall aggregate and the aggressor aggregate comparing it with the liquidity that we see in the limit order book. If you don't like this view you can always change it up here to the configurations button and we'll deselect aggregate last trade. So now book map is displaying the last traded volume was three contracts at this price level.
