Direct Access Electronic Trading The issue of direct access is an important one and it becomes more important the more short term your trading is. The market can change from a state of seeming paralysis to one of shocking volatility and activity in a flash. The length of time it takes between you deciding to enter an order and the order actually being in the market is obviously important. When I first started trading I used a phone broker and was dismayed that my fills would often be so far from the price the market was trading when I first entered the order. The first time I visited the trading floor, I discovered why. When I called in an order, first my discount(!) broker would check my account equity, then he would call a phone booth on the floor, the phone broker on the floor would then write the order down and pass it on (by phone) to a booth next to the appropriate pit, at that booth my order would be written down again and then signaled to a broker in the pit to be executed.
