One of the main advantages of futures is the fact that they are traded on an exchange. The spread (the difference between the bid price and the ask price in the order book) is determined by all the orders of all the buyers and the sellers.Traders can avoid this spread, and thus increase their profit. The 'Auto Bid' and 'Auto Ask' buttons are the secret weapon to achieve this. A buyer, for example, can click 'Auto Bid'. The NanoTrader platform will place his buy order at the current bid price and will constantly keep it there. Even if the bid price goes up, NanoTrader instantaneously adapts the order to the new bid price. The buyer will always buy at the bid price but never pays the higher ask price. Having paid the low bid price, the position only requires a small market price movement to be profitable.
