OTC (over-the-counter) binary options use assets whose prices are generated internally by the broker rather than sourced from an external market or exchange. OTC instruments are typically available on weekends and public holidays when real financial markets are closed.
Why OTC Exists in Binary Options
Standard financial markets — stock exchanges, forex interbank markets — operate during defined hours. Weekends and major holidays produce no real market prices.
Binary options platforms offer OTC instruments to enable trading outside these hours. OTC prices simulate market-like price movement using an internal algorithm. The specific methodology is typically not publicly disclosed by the platform.
What This Means for Traders
No external price reference: There is no independent exchange or regulator setting OTC prices. The platform is the sole source of price data for these instruments. You cannot verify OTC settlement prices against an external source.
Lower payout rates: OTC assets typically carry lower payout rates than their exchange-traded equivalents. Check the live displayed rate before trading any OTC instrument.
Different volatility characteristics: OTC price movement is algorithmically generated and may behave differently from the same pair during live market hours — particularly around patterns and levels.
Availability: Most platforms label OTC assets clearly — often with «OTC» appended to the name (e.g. «EUR/USD OTC»). Some platforms display OTC availability only outside market hours.
