I'm sure this has been answered before but I have already searched and just got myself more confused.
I want to use Apex Copy Trader on ninja Trader software to copy trade multiple prop firms, namely TopStep, MFF and Take Profit Trader all I used Tradovate to trade on currently using CQG data feed, not Rithmic.
Apex says i need a multi broker licence key which i believe is now no longer available.
Do I simply need the $99 a month multiple broker add-on or wont this work?
