Market Map

No. Market Map is a stand alone indicator.
This problem is related to your data. As default Market Map use ticks as data collection type. If you don't have tick data, you will see a blank screen. Switch to the Minute option as your data collection type from the indicator setting window and ask your data vendor for tick data.
Sure you can, but we strongly recommend to always use 30 minute period as this time period has been discovered as the best time frame to use Market Profile.
