 You can use MultiBook Customizer to adjust contract factors to combine micro and mini contracts. For instance, if you're tracking both the mini and micro S&P 500 contracts, you won't need to hop between the screens. How do you do this? First, you need to make sure that the latest version of MultiBook is installed on your platform. For this, open Bookmap, go to Settings and click on Manage Plugins. On the window that pops up, click on the Bookmap Add-ons tab, find MultiBook and click on the Install button next to it. If you have a Remove button instead of an Install button, it means you already have the latest version of MultiBook installed. The next step is to add the CME mini and micro instruments. Click on the Plus tab and add both instruments. If you have trouble typing the right symbols, click the link above. After adding the instruments, all that's left to do is to use the MultiBook Customizer. Go to Settings and click on Configure Add-ons. Here, check the MultiBook Add-on. Expand the ES instrument and change the contract factor to 10, which is the ratio between the two. One point of the CME mini is worth $50 and one point of the micro ES is worth $5, which is the ratio 1 to 10. So to represent the ES contracts in micro ES terms, the factor for ES should be 10. If you'd like to determine the correct ratio between your desired instruments, take a look at the CME website by clicking the link in the description. Now, it just choose what you want to consolidate. DApps, Trades or BVO in both the CME mini and micro contracts and click on Create. The new synthetic instrument created now holds the correct ratio of the CME mini and micro contracts, 1 to 10.
