The captured demo: windows across the top, the price against the line, and the held call
Who it is for
Use it if you trade Polymarket crypto windows and want one considered call per window, an alarm, and an honest record of how the calls did.What it does
- Windows for BTC and ETH, in 15 minute and 5 minute series, shown as chips with settle time and countdown.
- Line and chart. Polymarket windows resolve on whether the price at the end is at or above the price at the start. The app shows an approximate start price and the live reference price against it.
- Helper tools, refreshed every 10 seconds: distance from the line, an edge meter, and live trade flow.
- One call per window, 5 minutes before settlement, then frozen: Up, Down or Pass with reasons.
- Alarm with sound and browser notifications on every Bet call.
- Track record with hit rate and profit and loss on a notional $100 per bet.
- Ticket to buy Up or Down with your key, showing your Polymarket balance.
What it needs
The reference price and trade flow come from Hyperliquid’s public data for the same coin.

Ideas to customize
Ask for changes like these after the build:Limits
- The line shown is an approximation of the official start price. Polymarket settles on its own source, and results are marked “by feed, awaiting official” until confirmed.
- 5 minute windows always pass, so calls come on 15 minute windows. Most windows are a pass.
- Orders are fill-or-kill with a 0.01 tick and a 5 share minimum.
- A call is a hint, not a promise. The track record lives in your browser only.
