Dynamic Spread Adjustment
Dynamic spread adjustment is the process of automatically changing the bid-ask spread in response to changing market conditions. When volatility is high or uncertainty is elevated, market makers widen their spreads to compensate for the increased risk of adverse selection.
When the market is calm, they tighten the spreads to attract more order flow. This mechanism is essential for maintaining a healthy and functional market, as it ensures that liquidity providers are appropriately rewarded for the risks they take.
In automated systems, this is managed by algorithms that monitor order book imbalance, volatility metrics, and recent trade history. Effective dynamic spread adjustment is key to balancing profitability with competitiveness in high-frequency trading.
