Study Notes:

IB’s Risk Navigator allows users to monitor risk in their live portfolios, but it also allows users to examine
the expected impact on a “what-if” portfolio under changing prices and volatility conditions. That could
be a really useful tool when it comes to estimating the price of an option over time as the price of an
underlying security moves, and for investors wanting to consider changes to expected movements

Access the Risk Navigator and create a New Portfolio. In this example we will use a basic bull call spread
using options in ticker IBKR to demonstrate. Add the underlying security and the respective call options
and select your desired expiration date.

In this example, we can display the Implied Volatility reading for the two options by adding this field
from the Metrics menu at the top of the page and selecting from the Contract Risk field. This displays
the individual implied volatility readings for both options.

Use the Report Viewer to drive the content of the plot below by selecting the ticker from the dropdown
menu. The default view shows Equity Portfolio Value Change and depicts how the value of the account is
expected to change on the y-axis as the value of the underlying changes on the x-axis. At the current
price for the underlying security, there is no expected change in the value of this call spread and so the
profile cuts the x/y axis at precisely zero.

What we want to know is how the account is impacted dollar-wise in the event we change the price of
the security, implied volatility or the number of days to expiration. Step 1, Step 2 and Step 3.

Under the Market Scenario, the live prices of the underlying and both options are displayed. In this case
we can determine the net premium paid for this vertical call spread by subtracting one premium from
the other.

In order to look ahead or to make changes to price and volatility, create a Custom Scenario from the
View dropdown menu. This creates a mirror-image view of everything displayed under the Market
Scenario. We also have an input area to edit certain values.

Select the underlying ticker and enter a new price. You may either enter a new explicit value, a dollar
change or a percentage change. Select the desired Type from the dropdown menu.

In this example I will increase the price of IBKR to an explicit value of $45.00. You can see that the values
change from black to red indicating an edit has been made. To put this change into action – hit the Apply
button at the top of the Editing field.

The change will be reflected in the Custom Scenario and will allow you to see the premium for both
options at the new price. You may compare those prices to the Market Scenario.

Given the increase in the price of ticker IBKR we can show the individual legs of the spread and so
calculate the new price for the spread.

Next we can examine the impact on option premiums in the event we change implied volatility readings.
Enter a new value for implied volatility and hit apply. Compare the calculated option premiums
displayed under the Custom Scenario with the original Market Scenario to see the impact of how
expected movement for the underlying can impact the value of each option.

To step forward in time, users may also adjust the date by making edits to the calendar. Click the Edit
button under Date and choose any date through expiration. In this example I will maintain changes to
both price and implied volatility but advance time by around a month. Click Apply and the Custom
Scenario will display the adjusted premiums for price, volatility and time.

Conclusion – Use the Custom Scenario within IB Risk Navigator to estimate the forward price for option
contracts. There, users may formulate strategies in advance helping them understand the impact on
premium of changing price and volatility through time. This may be extremely useful for investors
wanting to find an appropriate entry and exit points for their strategies.
