Spread Preview Ladder
After configuring the legs of the spread and selecting your price display or formula, the spread prices display in the Spread Preview Ladder in the Configuration Dialog Box. The Spread Preview ladder shows the number of current bids and offers at each price level in the market, which allows you to preview what is displayed in the MD Trader Spread Pane before launching the spread.
Note: As you enter a custom spread formula, MD Trader generates a preview of the synthetic market in the Spread Preview Ladder. The spread price updates on each keystroke when editing a custom formula.
