If you have a margin account and shares you own are loaned for short sales, there is no impact on your ability to trade those shares later. You can tell if you have a margin account if “Margin trading” is enabled in the Elections & routing section of Client Services > My Profile > General. If you have a cash account, your shares will never be loaned for short sales. TD Ameritrade makes shares available for shorting only from margin accounts when margin is being used. There is no guarantee that TD Ameritrade can continue a short position for an unlimited time. Please note: When short selling, the risk of loss is potentially unlimited and you may be required to cover your short position at an unfavorable price. The stock you want to sell short must be marginable.You must have an account that is approved for margin with $2,000 margin equity (non-retirement account).These are the requirements for short selling at TD Ameritrade: Orders to sell short are placed with the anticipation that the market price of a security will decline so that you may then purchase the security (buy to cover) at a lower price. Short selling is a sale of a security that you do not own.
