To assist with submitting and modifying orders in the Dynamic Price Ladder display during volatile market activity you can choose to suspend (freeze) the Price Ladder display by pressing the HOLD button with your left mouse button or by pressing the 'Space' bar of your keyboard.
Once suspended, the button will highlight red in color and display 'HELD'. You can now safely submit or modify an order without the price of the underlying row changing. Be sure to enable the dynamic updating of the price action in the price ladder display after you have completed your order submission or modification by pressing on the HELD button or your keyboard 'Space' bar. In addition, the inside market will be displayed in the top row of the SuperDOM while the price ladder is frozen.
