Intraday Trading Costs

Friction

Intraday trading costs represent the cumulative financial drag experienced by a market participant when initiating and closing positions within a single trading session. These expenses originate primarily from the bid-ask spread, which serves as the immediate premium paid to liquidity providers for instantaneous execution. Traders must also account for commissions levied by centralized exchanges or protocol-level fees inherent to decentralized automated market makers. Frequent turnover of positions intensifies these costs, potentially eroding the net expectancy of short-term alpha generation strategies.
