Show your trading PnL on your iPhone

Short answer: send your trading profit and loss to WidgetDash with one HTTP request, then add the WidgetDash widget to your iPhone Home Screen or Lock Screen. It updates every time you push a new value, and it is free for up to 5 numbers.

Knowing your profit and loss without opening a brokerage app keeps you calmer and more disciplined. Compute the day's and the week's PnL in your own script from your fills or positions and push both. The widget gives you the figure that matters with none of the noise of a full trading screen.

Push it with one request

A source is created automatically the first time you push to it, so there is no setup step. Send your trading profit and loss like this:

curl -X PUT https://api.widgetdash.app/api/v1/data/trading_pnl \
  -H "Authorization: Bearer YOUR_WRITE_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "display_name": "Trading PnL",
    "icon": "chart.bar.fill",
    "category": "Finance",
    "metrics": [
      { "label": "Today", "value": "+$840" },
      { "label": "Week", "value": "-$210" }
    ]
  }'

• The value is a plain string, so format it however reads best: "$8,420", "99.98%", "+58".
• icon is an SF Symbol name. Here we use chart.bar.fill.
• Push to the same source_key again any time and the widget updates in place.

Add it to your iPhone

1. Sign up free and copy your WRITE key from the dashboard.
2. Install the WidgetDash iOS app (free on the App Store) and connect with the dashboard QR code or your write key.
3. Long-press the Home Screen, tap +, search WidgetDash and pick a size. Small shows your first source, so use Edit in the app to move this one to the top.

Lock Screen widgets (rectangular and round) are supported too, so your trading profit and loss can sit right under the clock.
