SureTrader is for desperate gamblers. Don't have money and want to have a ride til zero there. Really bad broker, brought by shady people with criminal past (re stock schemas). Very high fees if you didn't notice. The platform is good for children. The DAS platform, if you will pay extra for it, is better as its a fast native app (what an uncommon approach *unfortunately*), but this company is again ran by the same shady people. If you forget your short position, they will charge a sky-high fee before eod, and they like to increase this fee at some days (a "bonus"). This bad practise is no existing at good brokers. Research data don't exist. Deposits and withdrawals are expensive as hell and can take a LOT of time. I won't be surprised if this broker will suddenly disappear from the scene, with your money.
If you still want to jump in after reading those reviews out there, there's a problem between monitor and keyboard.
