Frictionless Market Fallacy

Market

The Frictionless Market Fallacy, prevalent in cryptocurrency derivatives and options trading, assumes that market prices instantaneously reflect all available information and that trading costs are negligible, leading to perfect price discovery. This assumption disregards the realities of market microstructure, including order book dynamics, latency arbitrage, and the impact of high-frequency trading strategies. Consequently, models built upon this fallacy can significantly underestimate execution risk and fail to accurately predict price movements, particularly during periods of heightened volatility or liquidity constraints. A more nuanced understanding of market frictions is crucial for developing robust trading strategies and risk management protocols.
