Whoever you use to trade you will generally (probably 99% of the time) be unable to place a trade that has a value of less than $500 excluding brokerage. You can confirm this withyour broker if you wish.
Again, depending on who your broker is, you can check the course of day's sales and see the volume and value of each trade. If it's less than $500 worth and/or they look like common amounts being repeated at regular intervals throughout the day, then this is a BOT (Robot or Algorthmic Trading - in other words a computer) which is either a market maker that is able to place trades without brokerage for themselves or some other significant player.
