I'm looking for a charting application and have been doing some searches in this forum. If I have an ameritrade account will that be able to feed the sierra chart application for a live feed for futures? I.E. will the chart create in real time over the course of a day a real market profile chart? Also is the TPO chart for sierra charts the same as the Market Profile chart for investor RT? Is is just all in the name as Sierra does not charge you the CBOT liscense fee.
