Commissions and Fees

Commissions are fees paid to a broker for executing trades. For high-frequency traders and scalpers, commissions are a significant cost that must be overcome by the trading edge. Net P&L = Gross P&L − Commissions.

Why it matters for traders

For short-term traders, commissions directly impact profitability. A scalper paying $5 per trade must make more than $5 per trade on average to break even — before considering slippage. Tracking net P&L including commissions is essential for honest performance evaluation.

How Tradapt tracks this

Tradapt tracks commissions separately and includes them in net P&L calculations. Compare your gross and net P&L in Analytics to see the true cost of commissions on your strategy.

Frequently asked questions

How do commissions affect trading profitability?

Commissions reduce net P&L on every trade. For scalpers making small gains per trade, commissions can represent 50% or more of gross profit. Track your gross vs net P&L in Tradapt to see the real impact of fees on your edge.
