How do I create a Conditional order in TWS?

You can create a Conditional order in Classic TWS layout. First set up the order you wish to have triggered and then attach a Condition to it:

1. Enter a symbol into your Quote Monitor/Watchlist
2. Click the Ask to create a Buy order or the Bid to create a Sell order
3. On the Order line, modify the order parameters including Time in Force, Action, Quantity, Price, Order Type, and Destination
4. Right click on the order and click Modify followed by Condition. Click the Add button on your right to choose which type of condition you wish to set. Types of conditions include Price, Margin Cushion, Volume, Percentage Change, Rebate Rate in %, Time, Trade, or Shortable Shares. Choose your condition type, click the Next button, and follow the prompts to finish setting up your condition
5. Once finished, you will be brought back to the Order Ticket window
6. Once you are ready to Transmit your order, click the blue Transmit button at the bottom of the window (or "T" if you have reduced the size of the Transmit field). 

Please Note

• The Add button will be grayed out if the order has already been submitted as you cannot add a condition to an outstanding order. The condition will need to be added prior to submitting the order
• Conditional orders are supported in the Classic and Mosaic TWS layouts via Order Ticket only as of TWS Build 981. It is not possible to attach a Condition to an order created in the Mosaic layout via the Order Entry window. See: How can I create a Conditional order in Mosaic?
