One of my Coinbase Advanced Trade bots stopped running and I didn't notice for hours. API key had expired silently — no errors thrown, nothing in the logs, just quiet while the market moved without me.

That was the whole motivation. I built PositionPing to solve exactly that problem.

\*\*What it does:\*\*

• Watches Coinbase Advanced Trade accounts around the clock
• Fires email or SMS alerts when a position's P&L crosses a threshold you set, an account stops sending fresh data (stale/hung bot), a daily loss limit is breached, or a balance changes unexpectedly
• View-only API keys only — it physically cannot trade or move funds, enforced at the Coinbase API scope level

\*\*Stack:\*\* nothing exotic. The hard part was getting the monitoring logic tight enough that it catches real failures without firing false positives at 3am.

\*\*Where it's at:\*\*

• Live at [positionping.com](http://positionping.com) \- Free tier: email alerts, 1 account
• Pro: $9/mo, SMS + up to 5 accounts
• \~2 min setup, mobile app available

Took a few weekends to get to something I'd actually trust on my own accounts. Happy to talk about the build — the API polling logic, alert delivery, anything.

I run a few trading bots on Coinbase Advanced Trade. A while back, one of them just stopped. API key had expired quietly — no errors, no alerts, just silence while the market moved. I didn't catch it for hours.

The frustrating part wasn't the loss. It was that there was no reason I should have been in the dark. I had no monitoring in place and was relying on the bot to tell me when something was wrong. Wrong design.

So I built PositionPing. It watches your Coinbase Advanced Trade accounts 24/7 and sends alerts when things go sideways — P&L crossing a threshold, account going stale (no new data, hung bot, expired key), daily loss limit breached, or an unexpected balance change.

Security was the first thing I figured out: it only ever uses view-only API keys. Read-only scope, no trading permissions, no transfer permissions, no withdrawals. Ever. You can verify this yourself in the Coinbase API key settings — the scope is enforced at the API level, not just a policy on my end.

Setup takes about 2 minutes. Free tier covers email alerts on one account indefinitely. SMS alerts and up to 5 accounts are $9/month. There's also a mobile app if you want it on your home screen.
