Portfolio Reader

Purpose

Read and analyze local portfolio snapshots from Tradeville (Romanian broker) and IBKR (Interactive Brokers). Provides a unified view across both accounts.

Where Data Lives

All portfolio data is local-only (gitignored):

.claude/local/portfolio/snapshots/
├── tradeville-YYYY-MM-DD-HHMM.json     # Tradeville positions
├── tradeville-YYYY-MM-DD-HHMM.png      # Tradeville screenshot
├── ibkr-positions-YYYY-MM-DD-HHMM.json # IBKR positions (from API)
├── ibkr-summary-YYYY-MM-DD-HHMM.json   # IBKR account summary (NAV, cash)
├── ibkr-web-YYYY-MM-DD-HHMM.png        # IBKR screenshot (visual verification)

How to Read Snapshots

Step 1: Find Latest Files

ls -t .claude/local/portfolio/snapshots/*.json 2>/dev/null | head -5

Or use glob to find the most recent by timestamp pattern:

• Tradeville: tradeville-*.json (positions array)
• IBKR positions: ibkr-positions-*.json (positions with market values)
• IBKR summary: ibkr-summary-*.json (NAV, cash, margin, buying power)

Step 2: Read JSON Data

Tradeville JSON contains a positions array with:

• Symbol, quantity, average price, current price
• P&L (realized and unrealized), market value
• Currency (RON-denominated)

IBKR positions JSON contains:

• Contract details (symbol, exchange, currency, asset class)
• Position size, market price, market value
• Average cost, unrealized P&L
• Multi-currency (USD, EUR, etc.)

IBKR summary JSON contains:

• Net asset value (NAV)
• Cash balances by currency
• Buying power, margin requirements
• Total account value

Step 3: View Screenshots (Optional)

Read .png files for visual verification. Useful when JSON extraction may have missed data or when the user wants visual confirmation.

Analysis Capabilities

Unified Portfolio View

Combine Tradeville + IBKR data into one view:

1. Read latest JSON from both brokers
2. Normalize currencies (RON positions from Tradeville, multi-currency from IBKR)
3. Present total portfolio value, position-level detail, allocation breakdown

Sector Allocation

Group positions by sector/geography:

• Romanian equities (Tradeville)
• International equities (IBKR)
• Energy sector exposure (cross-reference with oil prices from macro-monitor)
• Geographic concentration risk

P&L Analysis

• Per-position unrealized P&L
• Total portfolio P&L
• Best/worst performers
• Cost basis vs current value

Historical Comparison

Compare snapshots across dates:

# Find snapshots from different dates
ls .claude/local/portfolio/snapshots/tradeville-*.json

• Diff positions between dates (new/closed positions, quantity changes)
• Track portfolio value over time
• Identify trends in allocation shifts

Cross-References

With macro-monitor

• Oil prices (Brent): Affect energy sector positions (Romgaz, OMV Petrom)
• EUR/RON rate: Affects Romanian stock values when comparing to EUR/USD portfolio
• Interest rates: Impact bank stocks and bond positions
• VIX: High VIX may warrant defensive rebalancing

Run macro-monitor's crisis check for context:

python3 projects/ex-cog-dev/research-toolkit/skills/macro-monitor/scripts/fred_fetcher.py crisis

With stonk agent / cui-bono

Before making investment decisions, use the stonk agent (or cui-bono directly) for:

• Power structure analysis of potential new positions
• Ethical constraint evaluation
• Multi-polar dynamics assessment

With deep-investigation-protocol

For in-depth analysis of specific holdings or sectors:

• Use DIP for company-specific deep dives
• Combine with portfolio data to assess concentration risk

How to Update Data

Portfolio data is now collected via the portfolio-mcp MCP server (projects/ex-cog-dev/research-toolkit/mcp-servers/portfolio-mcp/).

Tradeville (4-step workflow)

1. tradeville_login — Instructions to run login script in a terminal (MCP stdin is reserved for JSON-RPC; login must happen outside MCP).
2. tradeville_discover — Opens browser with CDP port for Claude to navigate. Claude calls tradeville_save_sub_account for each sub-account found, then calls tradeville_finish_discover to close the browser.
3. tradeville_set_active_account — Set which sub-account to use for routine snapshots.
4. tradeville_snapshot — Auto-approvable. Navigates to portfolio page; if the sub-account URL uses the click: prefix (e.g. click:Subcont PERSONAL), clicks through the dropdown to switch sub-accounts. Saves screenshot + JSON.

IBKR

1. ibkr_login — Opens visible browser for Client Portal Gateway auth (requires gateway at localhost:5000).
2. ibkr_snapshot — Auto-approvable. Calls REST API, saves positions + NAV to JSON.

Status check

portfolio_status  — shows auth state, discovered URL, recent snapshots

Data dir: ~/.claude/local/portfolio/ (or $PORTFOLIO_DATA_DIR).

When to Use This Skill

Trigger	Action
User asks "what's in my portfolio?"	Read latest snapshots, present unified view
Before investment decision (task #36, #39)	Read current positions to avoid duplication/overconcentration
Macro indicator changes significantly	Cross-reference positions with macro-monitor data
User asks about specific position	Find it across both brokers, show details
User asks about allocation/exposure	Calculate sector/geography breakdown

Vasana

A vasana is a pattern that persists across unrelated contexts. If during this task you notice such a pattern emerging, it may be worth capturing. This skill works best alongside the vasana skill and vasana hook from the Vasana System plugin.
