Dynamic Tick Size Adjustment: Optimizing Price Granularity in Real Time

Tick size — the minimum price increment at which assets can trade — plays a crucial role in shaping liquidity and spread behavior. If the tick size is too wide, spreads remain artificially large. If it is too narrow, order books become fragmented with excessive micro-level competition. Dynamic tick size adjustment solves this by adapting price granularity to real-time market conditions.

On Xoibit, a dynamic tick framework evaluates volatility, average spread, order book depth, and trading frequency. When volatility increases, tick sizes can expand slightly to reduce excessive noise. When markets stabilize, tick sizes can narrow to promote tighter spreads and price competition.

This adaptive model improves both liquidity efficiency and execution quality. Larger ticks during high volatility reduce quote flickering and encourage meaningful size at each price level. Smaller ticks during stable periods enhance price discovery and reduce transaction costs.

Implementing dynamic tick logic requires careful safeguards. Changes must be transparent, predictable, and synchronized across all systems to prevent confusion or pricing discrepancies.

By aligning price increments with real-time market behavior, Xoibit ensures that trading conditions remain optimal across different liquidity regimes. Tick size becomes a flexible tool rather than a fixed constraint.
