When using ScaleTrader for creating generic combination orders, note the following:
When you create a STK STK generic combo, the ratios are automatically simplified when you save the combo. This means that the combo you define in the Combo Selection box to Buy 300 XYZ and sell 700 ABC ends up on the ticker line as Buy 3 XYZ and Sell 7 ABC.
Scale parameters such as Total Order Size and Initial and Subsequent Component sizes are expressed in terms of the total combo. For example, if you buy a generic STK STK combo defined as Buy 10 DELL, Sell 1 IBM, and set the Initial Component Size to 5, the first component order would be: Buy (5 x 10) DELL, Sell (5 x 1) IBM.

If you opened ScaleTrader with an underlying selected, click the Edit Combo button; otherwise, enter an underlying and select from the combo type, including EFP, Futures Spread or Option Combo.
Use the ComboTrader box to define a strategy, and click Create.
You can monitor the progress of your scale orders by right-clicking on the order line and selecting View Scale Progress.
