Current Limitation

The model tool currently recalculates total costs when legs are added or removed, making it impossible to track adjustments to existing positions. This prevents proper P&L analysis of rolling, adding hedges, or modifying spreads.

Market Opportunity

Target Audience Expansion

This feature targets traders currently using OptionStrat or ONE for trade tracking - a significant market segment who:

Trade complex option strategies manually (no automation)

Need to track multiple adjustments throughout trade lifecycle

Require accurate P&L tracking across rolling, hedging, and modifications

Want visualization tools for position analysis

Future Product Direction

Building robust adjustment tracking creates a foundation for an order entry and trade management tool for manual traders who:

Don't use automated strategies in OO

Need professional-grade order entry capabilities

Want to enter, monitor, and exit complex trades efficiently

Prefer OO's visualization and analysis over competing platforms

Trade dynamic strategies that require frequent adjustments (iron condors, butterflies, calendars, diagonals)

This positions Option Omega as both a strategy automation platform AND a comprehensive manual trading tool, capturing users across the trading sophistication spectrum.

Proposed Solution (Simple Version)

Core Functionality

When reopening a saved model and modifying legs:

Preserve the original trade cost as a baseline

Calculate incremental cost/credit for new legs separately

Display both original cost and adjustment cost

Show cumulative total cost

Pricing Input Method

Instead of entering total trade cost, allow users to input:

Spread price (debit/credit per contract)

Quantity (number of contracts)

System calculates: Total Cost = Spread Price × Quantity × Multiplier

This matches standard trading platform workflow and eliminates manual calculation errors.

Save Workflow

When saving an adjusted trade:

Prompt user to specify the spread price and quantity of the adjustment

System calculates adjustment cost automatically

Store adjustment as a separate transaction

Calculate new total cost: Original Cost + Adjustment Cost

Maintain adjustment history for reference

Example Flow

Open saved butterfly: 5 contracts @ $1.50 debit = $750 total cost

Add 3 upper long calls (adjustment)

System prompts: "Enter adjustment spread price and quantity"

User enters: 3 contracts @ $0.50 credit = -$150

New total cost: $750 - $150 = $600

Graph updates to show modified position

Enhanced Solution (TOS-Style)

Multi-Transaction Tracking

Implement a transaction log that:

Records each spread/adjustment as a separate entry

Tracks individual transaction prices, quantities, and calculated costs

Maintains chronological order of adjustments

Displays cumulative cost at each step

Transaction Entry Format

text

Transaction 1: Open 50/55/60 Butterfly | 5 contracts @ $1.50 | Cost: $750

Transaction 2: Roll upper longs to 65 | 5 contracts @ $0.50 credit | Credit: -$250

Transaction 3: Add 45 Put hedge | 3 contracts @ $0.35 | Cost: $105

Total Position Cost: $605

Pricing Input for Each Transaction

Enter spread price (per contract)

Enter quantity

Specify debit or credit (or auto-detect from price sign)

System calculates and displays transaction total

Updates cumulative position cost

Visual Features

Graph displays current combined position

Transaction list shows adjustment history with pricing details

Hover over transaction to see that specific spread's payoff

Toggle individual transactions on/off in visualization

Show breakeven points before and after adjustments

Display cost basis per contract for the overall position

Benefits

Accurate P&L tracking across multiple adjustments

Ability to evaluate "what-if" scenarios without losing data

Historical record of trade management decisions with exact pricing

Better analysis of adjustment effectiveness

Matches professional platform capabilities (TOS, TT, Tastytrade)

Eliminates manual cost calculations and potential errors

Competitive positioning against OptionStrat and ONE for manual traders

Foundation for future order entry/management tool development

Technical Considerations

Store adjustments in array/list structure within saved model

Each adjustment needs: legs, spread price, quantity, calculated cost, timestamp, description

Graph engine must aggregate all transactions for combined payoff

UI needs adjustment history panel/section

Support for standard options multiplier (100) and other products if needed

Consider future integration points for broker order routing

Long-Term Vision

This feature serves as Phase 1 toward a comprehensive manual trading solution:

Phase 1: Adjustment tracking and cost analysis (this request)

Phase 2: Live position monitoring and P&L updates

Phase 3: Order entry interface with broker integration

Phase 4: Full trade lifecycle management (entry → adjustments → exit)
