Transaction Cost Analysis
Transaction cost analysis is the systematic evaluation of the total expenses incurred when executing a trade, beyond just the nominal asset price. This includes explicit costs like trading fees, withdrawal fees, and blockchain gas costs, as well as implicit costs such as slippage and market impact.
For arbitrageurs, this analysis is the final filter that determines whether a potential opportunity is actually profitable. In volatile crypto markets, gas fees can spike unexpectedly, potentially eroding the entire profit margin of an arbitrage trade.
Traders use this analysis to optimize their trade sizing and timing, ensuring that the net revenue consistently exceeds the friction costs of the transaction. By modeling these costs accurately, participants can avoid entering trades that appear profitable on the surface but result in a loss after execution.
