BTC 5-Min Trading
Bet whether BTC closes above or below the 5-min open. A new market opens every five minutes, 24/7.
TL;DR
Each 5-min window has a target price set by Binance's candle open. Pick Up or Down before close. Winning shares pay $1, losing shares pay zero. Chainlink settles automatically on-chain.
How it works
1
A new window opens every 5 minutes
Each window has a target price. that's the BTC/USDT open price at the start of the 5-minute candle, pulled from Binance.
2
Buy Up or Down
Think BTC will finish above the target price? Buy Up. Think it'll finish below? Buy Down. Prices are in cents. so a 70¢ Up price means the market puts a 70% chance on BTC going up.
3
Window resolves
When the 5 minutes are up, the market resolves based on where BTC ended up vs the target. Winners get $1 per share.

Order types
| TIF | Name | Behaviour on BTC 5-min |
|---|---|---|
FAK | Fill and Kill | Default for ALL BTC 5-min trades regardless of size. Fills whatever's on the book at your price right now, cancels the rest. |
FOK | Fill or Kill | Available manually. All-or-nothing — risky on a fast market with thin liquidity, only useful for tiny test orders. |
GTC | Good Till Cancel | Available manually. Sits on the book until it fills or the window closes (windows last 5 minutes, so GTC is mostly defensive limit-pricing). |
Why FAK by default: BTC 5-min books move fast, and a FOK that fails to fill the full size cancels everything — which is the opposite of what you want when price is running. FAK partial-fills get you in at the price you saw and lets the rest chase if there's more depth.
Tips
- ●You can trade future windows before they go live. you'll often get better prices early.
- ●Keep an eye on the countdown. liquidity dries up as a window gets close to closing.
- ●
FAKworks better for bigger orders since you'll get partial fills instead of all-or-nothing. - ●Save your go-to setups as presets (P1, P2, P3) — long-press or right-click to edit them.
- ●The Recent Windows row shows resolved windows as green/red squares so you can quickly spot patterns.
