 Let's go through the Current Order Book column in Bookmap. I'll right click in this column and come down and select the data type, Current Order Book. This column is displaying the amount of liquidity here at each specific price level. The header up here, COB, stands for Current Order Book. This is your dome, your depth of market. What we're looking at here on the offer above current price, these numeric values here represent liquidity. These are limit orders that are available here for sale at these specific price levels. These are where sellers are lined up providing liquidity here on the offer. Down below current price, they're providing liquidity down here on the bid. So for example, down at 2660, we can see there is 212 contracts available for buying. Let's right click in the column and choose Configure. You have a variety of different visual options here to show either the ask or to show the bid or both. You can also show the extended book. Now I have full depth of market here, so all levels here are live. However, if you have a limit order book, let's say with 10 levels live on the offer and 10 on the bid, and you select the box for extended book, what you're going to see is liquidity that's available above current price that is not live, it is historical. However, it will be displaying the liquidity that was previously available when it was live at that time. You can also access an aggregate view of the current order book. In the aggregate view, it takes the liquidity at the best offer, for example, here and adds it to the next price level above it and so on. That's an aggregate view of all of the liquidity. This view can be helpful to understand specific skews in the book where a lot of liquidity might pop in and skew the auction. You can also set the maximum depth here if you want to look at a specific amount of price levels. So for example, looking at 10 here, and you can see that the white number above the 10 levels here on the offer is displaying the aggregate view of all of that liquidity for those 10 levels. You can also play around with the different settings here for showing bars, bars and numbers, or numbers only. You have some styling options here to split out the data. You can inverse the split if you like, or come back to this view here and align it to the left, to the center, or to the right. You can open up multiple COB columns and configure them in a variety of different ways, and build out your depth of market however you choose fit.
