 Multibook is a book map add-on feature that allows for the creation of synthetic instruments. Users can add multiple order books or exchanges all within one symbol. It currently works for the crypto environment but will be enabled for stocks and futures sometime in the near future. Let's go through a quick example. Here we're looking at Bitcoin in the crypto exchange Bitstamp. Note the liquidity around 58, 900 poles as price nears it. Next, let's switch over to Binance and note how their liquidity is at a different price level of 58, 800 and it stays in the book and fills. If we switch over to Coinbase Pro, you can see it's similar to Bitstamp except the pulled liquidity is at 58, 800 instead of 58, 900. Now let's jump over to Hobie and it looks altogether different around 58, 800 since their order book doesn't offer full depth of market. In fact, you see quite a bit of filled liquidity on the bid at 58, 750. Finally, let's take a look at the Multibook synthetic instrument MBBTC. This instrument is a chart composed of all four exchanges combined into one. It shows liquidity filled at 58, 800 and also other important details such as sell volume down at 58, 700 and liquidity on the bid around the 58, 500 area that some of the other exchanges completely missed. The composition of these four exchanges altogether within one instrument gives you a much more objective view of what's really going on within Bitcoin. This allows you to make much better trading decisions. To create a synthetic instrument like this, it is done very easily and automatically within Bookmap's current alpha version 7.3. To download 7.3 alpha, go to bookmap.com slash current slash alpha. Note that trading is not yet supported via Multibook synthetic instruments. To find out more about Multibook, go to bookmap.com. Click on the more button on the toolbar and go to the knowledge base. Then click on add-ons in the top right section of the knowledge base. In the add-ons section in the left margin, click on Multibook here and you will see all the information about Multibook including download links, installation guides, configurations, notes and FAQs. Multibook for crypto is also supported in Bookmap 7.1 and 7.2, but the process is done manually and is a bit more involved. Let's restart Bookmap 7.2 and go through an example. I've restarted Bookmap 7.2 and have already added Bitcoin in the cryptocurrency exchanges Bitstamp, Binance, Coinbase Pro and Hoby. This is required in order to create a synthetic instrument within Multibook. To connect to these exchanges, go to settings, manage connections and add the proper exchange adapters. Then go to connections and configure the connection just like you would any other connection. Then select the connections and add the instrument of choice. I've already gone through this process and added Bitcoin for these exchanges. So now let's add the Multibook add-on for Bookmap 7.1 and 7.2. You'll find the download link in the Multibook knowledge base section we just covered. We'll skip the process for adding an add-on within Bookmap since it was already covered in a previous video. Once you've added Multibook, click on the configure add-ons tool, select Multibook and click on it. In the settings section, let's jump down to the instruments available for selection. I'll choose the depth and trades for these four Bitcoin instruments. But I'll leave Best Bidin' Offer unchecked for now. A synthetic Best Bidin' Offer will be created based on a virtual midpoint for the composite of these four exchanges. Note that in the section above you can now give the instrument a name as well as select the desired tick size and granularity here. The default for this is 0.01. However, each exchange may not offer this detailed setting. So you'll likely need to return and edit the sizing in order to conform to all of the exchange's smallest setting. For this example, I'll choose 0.1. Now let's click create. Note the new synthetic instrument pops up in a new instrument tab. Also note we've created a new instrument here and can add another by clicking on the plus tab. You can edit the symbol here if you need to rename or change the sizing. Let's close the window and check out our new synthetic instrument. Now let's suppose your exchange of interest is BitStamp and you'd like to see its Best Bidin' Offer on the chart. Let's go back to the configure add-ons tool, select our multi-book instrument and select Best Bidin' Offer only for BitStamp. No need to edit it, multi-book will add it on the fly. Let's also click here to open BitStamp and you can see the sizing details of this exchange as well as the Best Bidin' Offer colors. Edit the colors as desired. Let's close the window and go back to the chart. You can now see the synthetic Best Bidin' Offer as well as BitStamp's BBO. If you wish to deselect the synthetic BBO, you can click on the configure visible components tool here to deselect it.
