How do I use the "Pair or Leg-by-Leg" tab in the Combo Selection window?

The Pair or Leg-by-Leg tab of the Combo Selection is the most flexible tool to create a combo.

To select a combo with the Combo Selection window's Pair or Leg-by-Leg tab:

  1. Enter the underlying symbol into a market data line and select Combinations followed by Option Combos (SMART), Future Option Combos (SMART) or Futures Spreads (SMART)
  2. Click the Pair or Leg-by-Leg tab
  3. Drag your selection of stocks, options, or futures tickers from your quote monitor or OptionTrader into the tab
  4. Alternatively, click in the Underlying field and enter the underlying symbol once again. Hit Enter and choose the option or future you wish to add as your first leg
  5. Repeat for any subsequent legs you wish to add.
  6. Select Create (1:1) price combo to display the price of the combo as if it were a 1:1 price combo regardless of the legs ratio
  7. Select Request market data for legs to add market data lines for each combo leg
  8. Click Clear if you want to clear your selection
  9. Once finished, click the Add button to add the combo as a market data line to your watchlist
  10. Click OK to close the window.

Please note: Although the order will be submitted for the legs ratio chosen upon combo creation regardless of Create (1:1) price combo set up, if Create (1:1) price combo is selected it is possible that less order types will be available. Un-check Create (1:1) price combo in order to see all order types.
