Forex Execution and Risk
Forex trading costs: spreads, commissions, swaps, and slippage
A trade can be technically correct and still produce a weaker result than expected when execution costs are ignored. Understanding the normal costs of trading helps you plan with more realistic risk, targets, and review notes.
The four costs traders should separate
Spread
The difference between the bid and ask. It is present when you enter and can widen when liquidity is thinner or uncertainty rises.
Commission
A separate broker charge on some account types, often quoted per lot or per side of the transaction.
Swap or financing
A credit or charge that can apply when a position is held through rollover. It can be positive or negative depending on the pair and direction.
Slippage
The difference between the requested price and the actual fill price when available prices move before execution.
Plan the risk first, then check whether costs leave enough room
A valid stop loss belongs where the trade idea is invalidated, not where a cost assumption makes the position look attractive. Once the stop is defined, calculate position size from the dollar risk you are prepared to accept.
Then ask a second question: does the setup still have adequate room after normal spread and commission costs? A very small target can become less practical when those costs consume a meaningful portion of its available reward.
Cost awareness matters around major releases, market opens, rollover, and low-liquidity periods. It is not a reason to assume the worst outcome; it is a reason to avoid assuming execution will always be perfect.
How to review costs after a trade
Keep trade quality separate from the cost of holding or executing it. A swap charge does not necessarily mean the setup was poor, and a profitable trade does not prove its execution was disciplined.
For each meaningful cost, record what happened and why: unusually wide spread at entry, a commission structure, overnight financing, or slippage during a scheduled release. Over time, those notes can reveal whether a recurring cost is part of your plan or an avoidable timing issue.
For live accounts, deposits, withdrawals, swaps, commissions, and fees also belong in account activity so the journal can remain focused on the trade itself.
A practical pre-trade cost check
- 1. Check the event calendar. Know whether a scheduled release could change liquidity or spreads.
- 2. Set the technical stop. Place it where the trade idea is invalidated, not at an arbitrary dollar amount.
- 3. Calculate position size. Use the account risk and stop distance to define exposure.
- 4. Confirm the trade still has room. Consider normal spread, commissions, and potential execution differences before entering.
- 5. Record unusual conditions. Make execution evidence part of the later review.
