Important Notes
Disable Global Simulation Mode
Be sure you are selecting to trade your ‘EARNMAX Trading’ account and not Sim101.  The Sim101 is for practice only and does NOT count toward qualification.  If you are trading the Sim101 account you will not see those trades register in R|Trader Pro.  If Global Simulation Mode is checked, it will not let you trade any account but the Sim101 account.
1.  Click Tools
2.  Click on the checkmark to the left of Global Simulation Mode to remove


Adding Commission values

Commissions are already subtracted and factored into the ‘Net Liquidation’ value.  The Chart Trader feature in NinjaTrader 8 ONLY shows Gross Profit and does not allow a Net Profit view.  The Trade Performance tool/analyzer likewise will only show profit without factoring in EARNMAX commissions, however you can import our commission template into your platform and all future trades will display commission fees.  


Contract Expiries

Be sure you are updating your futures instruments regularly to the current front month contract.

NinjaTrader 8 allows batch rollover across all instruments on all open workspaces.
