The Reference Synchronizer Indicator is the bridge between charts.

​

It allows the Market Profile indicator to send data to the Daily chart, the Daily chart to send data to the Market Profile Indicator, and the Weekly and Monthly charts to send data to the Market Profile Indicator as well as to the Daily chart.

This indicator can also be applied to a custom chart getting the data send by the Market Profile indicator  as well as the daily, weekly and monthly charts.

Please note that to get the needed data from charts they must be up and running.
