The Real Cost of Trading: Put Commissions and Fees in Your Journal

Open your journal and your broker statement side by side. If the monthly numbers do not match, the gap is almost always fees. Commission, exchange fees, clearing, platform charges: each is small, none of them are optional, and together they are often the difference between a profitable month and a flat one.

Why fees hit active traders hardest

Fees are a fixed cost per contract, not a percentage of profit. That makes them nearly invisible on a large winner and brutal on a small one.

Say your all-in cost is $0.75 per contract per side. A round trip on one contract is $1.50. If you are scalping micro contracts for $5 to $15 a trade, that $1.50 is 10% to 30% of the gross. Trade two contracts and take twenty trades a day and the fee line alone is $60.

Three consequences follow:

• Your real win rate is lower than your logged win rate. A trade that made $1 gross and cost $1.50 is a gross winner and a net loser.
• Your real average winner is smaller. Profit factor and expectancy computed on gross numbers are optimistic.
• Overtrading has a price you can see. Fees are the one cost of a low-quality trade that you pay even when it works.

What to count

Use the all-in number your broker or platform charges per contract, per side: commission plus exchange, clearing and regulatory fees. Check a real fill on a statement rather than the marketing page. For futures this is typically a flat figure per contract; for stocks and options it varies, so enter it per trade when it does.

Setting it up in ohYaaa

1. In your Profile, enter your all-in futures fee per contract, per side. New futures trades subtract it twice per contract (in and out), so Trade P&L matches your broker's net figure.
2. On any individual trade, the Fees / commissions field overrides the default. Use it for stocks, options, or the odd trade that was charged differently. Whatever you type comes straight off the result.
3. Losses show a minus sign throughout, so a fee-driven loss on a small winner reads as a loss rather than a rounded zero.

Because the fee is part of the trade, it flows into everything built on it: the dashboard, setup analytics, mistake costs, and the reports.

A quick audit you can do tonight

Take last month. Count your trades, multiply by your average contracts and your round-trip fee, and compare it to your net profit. If fees are more than a fifth of what you made, the first lever is not a better setup. It is fewer, larger-conviction trades on the same setups, and your setup analytics will tell you which ones to drop.

Journal the net number. It is the only one you can spend.
