Sign up for a TradeStation account and use the promo code ZINGAFOG to receive $100 after you add an initial deposit of $500 and maintain a balance of at least $500 for one month after opening. The TS Go account has no minimum balance requirement and no fees to simply keep the account open. There is a $10 fee for transfers using the desktop platform but not the app or web.
This deal is a great way to make an extra $100. Simply park $500 into the account for a month then withdraw after you receive your reward.
