Adjustment Modeling

What is Adjustment Modeling?

Adjustment Modeling lets you simulate proposed trades against your current portfolio before executing them. Add hypothetical positions to see how they would change your P/L curves, Greeks, and overall risk profile.

Enabling Adjustment Mode

1. Open the Adjustment Modeling tab in the left panel
2. Toggle Adjustment Mode to ON

When enabled:

• Your current portfolio becomes the baseline (frozen for comparison)
• Any new positions you add become proposed adjustments
• The P/L chart displays both baseline and adjusted curves

Adding Proposed Adjustments

With adjustment mode enabled, add positions from the options chain:

• Left-click to add a proposed buy
• Right-click to add a proposed sell

Proposed adjustments appear in the Adjustment Modeling panel with a “Proposed” indicator. They do not appear in your main portfolio table.

Editing Adjustments

Each proposed adjustment can be modified inline:

• Quantity - Click to edit the number of contracts
• Entry Price - Click to change the simulated fill price
• Remove - Click the X to delete individual adjustments

Understanding the Curves

The P/L chart shows two sets of curves when adjustment mode is active:

Curve Type	Appearance	What It Shows
Baseline	Dashed, lower opacity	Your current positions only
Adjusted	Solid lines	Current positions + proposed adjustments

Reading the Base/Adj/Delta Table

When you hover over the chart, the tooltip displays three values:

Column	Definition
Base	P/L from your current positions only
Adj	P/L from current positions + proposed adjustments
Delta	The difference (Adj minus Base)

Interpreting Delta

• Positive delta → Your proposed adjustments are projected to outperform holding your current positions at that stock price and point in time
• Negative delta → Your proposed adjustments are projected to underperform holding your current positions at that stock price and point in time

This helps you quickly see whether your proposed trades would improve or worsen your position across different price scenarios.

Net Credit/Debit

The panel displays the net premium for all proposed adjustments:

Value	Meaning
Positive (Credit)	You would receive premium
Negative (Debit)	You would pay premium

This shows the direct cost or credit of executing all proposed trades.

Controls

• Clear All - Remove all proposed adjustments at once
• Toggle OFF - Disable adjustment mode and return to normal view

Note: All adjustments in projectoption are modeled simulations only.
