To choose the best broker with which you want to use the aroon indicator, you must first ensure that the broker has a license in France or European approval and that it is a good reputation. Then, make sure that the platform that is offered by the online broker comes with the basic indicator or that it allows via a programmable script to add aroon, as for example with Trader Workstation, MT4, MT5. Finally, you must consult its fee schedule and commissions and you must ensure that the fees offered by the broker are in line with your investor profile.
