Small footprint - less screen space taken up, ideal for single-monitor setups or for notebook computers - less screen clutter means you can concentrate on your charts while trading.
Flexible window size - you choose how much information you want to show easily - less distractions while trading (all you need is a button to go long and a button to go short)
Flexible entry options - you can enter an order with just one click, or you can have complicated double breakout or double fade entries. The DOM (depth of market) window allows you to pick a price based on the number of bids and offers. You can even have a negative offset for Stop Limit entry orders.
Flexible exit options - if you are a multiple contract trader, you can scale out your positions automatically up to 3 steps, set a breakeven the way you want it and when you want it, start a trailing stop at the moment you want it, or have a "no target" for your runner. Or, if you are a more hands on trader, there is always the manual scale in and scale out.
Strategy saver -trade different strategies with different settings easily, no need for a separate window to enter your settings because the settings are saved as you tweak.
Time stop - reminds you when your trade is taking too long to reach your target.
