plugin	tradingview
description	Cancel a Working or Inactive order in TradingView via CDP (clicks the × button on the order row), then marks it cancelled in the Trade Log. Requires TradingView Desktop with --remote-debugging-port=9222.
allowed-tools	Bash, Read, Write

Trigger

Called when a trade-log entry with status submitted or inactive is cancelled from the Trade Log UI, or invoked directly by the user.

Planned (suggested/logged) entries are cancelled in JSON only — no TV action needed.

Prerequisites

• TradingView Desktop running with --remote-debugging-port=9222
• Order must be visible in TV's broker panel (Working or Inactive tab)
• Trade-log entry should have a tvOrderId field (populated on submission)

Method 1: Via Backend API (Trade Log UI)

The Trade Log × button calls POST /api/trading/cancel:

API_TOKEN=$(cat .runtime/api-token)
curl -s -X POST http://localhost:3001/api/trading/cancel \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $API_TOKEN" \
  -d '{
    "entryId": "1c96b4ce4b70",
    "tvOrderId": "292b5304-0c3d-42c2-02c0-290f6d322c12",
    "ticker": "INTC",
    "action": "Buy",
    "limitPrice": 47.00
  }'

The backend:

1. Calls place_order.py --cancel --order-id <tvOrderId>
2. PATCHes the log entry to cancelled regardless of TV result

Method 2: Python script (direct)

python3 plugins/tradingview/scripts/tv_cancel_order.py \
    --order-id 292b5304-0c3d-42c2-02c0-290f6d322c12 \
    --ticker INTC --action buy --limit-price 47.00

Method 3: place_order.py CLI

python3 investment_screener/backend/py_services/place_order.py \
    --cancel --order-id <tvOrderId> \
    --ticker INTC --action buy --limit-price 47.00

How It Works

cancelOrder() in tradingview-cdp/core/trading.js:

1. Searches the current DOM for an order row containing the UUID — without navigating tabs (tab navigation was toggling the broker panel closed)
2. Falls back to tab navigation only if the row is not found directly
3. Clicks the × button (buttonIndex: -1, last button in the row)
4. Waits for a secondary TV confirmation dialog ("Cancel order" / "Keep order") and clicks "Cancel order"
5. Waits 1 s, verifies the row is gone from the DOM
6. Returns { cancelled: true, verified: true, orderId, ticker, action }

Error Handling

• TV not connected: Backend still marks log entry as cancelled
• Order not found: Returns { cancelled: false } — order may have already filled/expired
• Tab navigation toggling panel: Solved by search-first approach (never navigates tabs)

Implementation Status

✅ FULLY IMPLEMENTED

• cancelOrder() — tradingview-cdp/core/trading.js
• --cancel flag — investment_screener/backend/py_services/place_order.py
• tv_cancel_order.py — plugins/tradingview/scripts/tv_cancel_order.py
• Backend route — POST /api/trading/cancel in investment_screener/backend/src/routes/trading.ts
• Trade Log UI — × button on Working/Inactive rows calls backend cancel endpoint
