Trading Fee Drag

Trading fee drag refers to the cumulative reduction in net returns caused by the repeated application of transaction costs during trading activities. In high-frequency or active trading strategies, these fees can significantly erode the compounding effect of gains over time.

Even if a strategy has a positive expected value before costs, frequent trading can turn it into a losing strategy once commissions and exchange fees are accounted for. This phenomenon is particularly pronounced in cryptocurrency markets where exchange fee structures can be complex and relatively high compared to traditional asset classes.

It forces traders to prioritize efficiency in their execution strategies to ensure that the costs do not outweigh the profit margins. Understanding this drag is essential for calculating the true breakeven point of any trading system.
