Why did the balance change without anyone clicking anything?

That's expected. Every open match has a real end time attached to it. Once that time passes, the match moves itself out of Open and into History automatically, and its profit gets added to the balance — no manual step required.

Is the profit shown actually guaranteed?

The profit on each match is fixed at the moment the arbitrage bets are placed — that's the nature of arbitrage, the outcome of the match doesn't change it. This page reflects whatever odds, stake, and profit were entered for that bet; it doesn't independently verify what a bookmaker actually pays out.

How often does this page update?

It refreshes automatically every 30 seconds. You can also just reload the page any time for the latest numbers.

Can past, settled matches be edited?

No — only matches still marked Open can be changed or removed. Once a match settles into History, it's part of the permanent record.

What timezone are match times shown in?

Match end times are stored in UTC and converted to your device's local timezone for display. The automatic settlement check itself always runs on UTC.

Is this financial advice?

No. This is a private tracking tool for one specific arbitrage betting arrangement between its two users — it's not general investment guidance and shouldn't be treated as such.
