In case this helps anyone: To see the Delta in Fidelity's Active Trader Pro (ATP), follow these steps: 1. **Access the Option Chain:** - Navigate to the "Options" menu and select "Option Chain." 2. **Customize the Columns:** - In the Option Chain window, right-click on any column header. This will open a menu where you can select "Add Column" or go to "Settings" to customize what data is displayed. 3. **Select Delta:** - From the list of available columns, choose "Delta." This will add the Delta values to your options chain display. 4. **View Bid Analytics for Detailed Greeks:** - For a more detailed view of the Greeks, including Delta, you can right-click on a specific strike price in the options chain and select "View Bid Analytics." This will give you a detailed breakdown of the Greeks for that particular option. 5. **Check Position Details:** - If you want to see the Delta for positions you own, go to the Positions window. Here, you can click on "Manage" in the upper right corner of the display to customize what information is shown, including the Greeks. 6. **Using Trade Armor:** - The Trade Armor tool within ATP also displays Delta when you expand each option contract to view additional details. This is particularly useful for managing exits and visualizing your potential gain/loss. Remember, the Delta value in ATP can be shown as a decimal fraction (e.g., 0.50) rather than a percentage (50%), which is something to keep in mind when comparing with other platforms or sources. These steps are based on information available on Fidelity's official support pages and user discussions on platforms like Reddit, where users share their experiences with ATP's features.
