FEES
Understanding the Parabolic Kalshi Taker Fee Schedule
Why taker fees peak at 50¢ ($1.75 per 100 contracts) and how resting maker limit orders reduce fee friction where applicable.
Kalshi taker fees follow the regulatory formula $0.07 × C × P × (1 - P), rounded up to the nearest cent. Trading at 50¢ incurs maximum taker friction ($1.75 per 100 contracts), shifting your required breakeven win rate to 51.75%. In general markets, posting resting limit orders (Maker mode) incurs $0.00 in trading fees, though limit orders carry non-fill and partial-fill risk and select contracts charge maker fees.
SETTLEMENT
How CME CF BRTI 60-Second TWAP Settlement Works
Kalshi KXBTC15M contracts resolve against the CME CF Bitcoin Real-Time Index TWAP, not spot prices on retail apps.
Settlement occurs across seconds 840–900 (the final 60 seconds) of the 15-minute contract window. CME CF calculates a Time-Weighted Average Price across 4 constituent spot exchanges: Coinbase, Kraken, Bitstamp, and Gemini. If spot swings in the final seconds, TWAP dampens the move.
RESPONSIBLE-TRADING
Responsible Trading: Loss Limits & the 15-Minute Tilt Shield
Built-in behavioral protections: setting daily/weekly max losses and understanding automated tilt cooldowns.
When 3 consecutive losses occur within 60 minutes or rapid re-entry is detected, QuanterraOS engages a 15-minute system cooldown overlay. While dismissable, respecting the cooldown earns +25 XP toward your Pilot Rank. Loss limits and fee budgets persist across your devices.
FLIGHT-DECK
Shadow Mode: Paper-Following Public Flow Without Live Routing
Paper-record copy fills on public Polymarket wallets or whale filters with realistic slippage and fee friction.
Under CFTC Rule 4.41 compliance, Shadow Mode models what you would have netted after fees, slippage (+1¢), and latency (250–350ms) without risking live capital or connecting brokerages. QuanterraOS never routes orders to exchanges.
