What Is Commission?
A fixed per-trade fee charged in addition to the spread on some account types.
On ECN accounts the spread is very tight but a per-trade commission applies; weigh both when assessing total cost.
Risk warning. Leveraged forex trading carries high risk and in Türkiye may only be offered by SPK-authorised intermediaries; leverage is capped at 1:10 (half of that may apply if the initial margin at account opening is below TRY 50,000).

Where commission sits versus spread
Trading cost in forex is not a single line. On standard accounts the cost is buried in the spread; on ECN-type accounts the spread is kept very tight but a separate per-trade commission applies. Different packaging, same pocket.
So "zero commission" alone does not mean cheap: if there is no commission, the cost has most likely moved into the spread. The right comparison is not one line but **total cost**.
How to compute total cost
The real cost of a trade is the sum of three items: spread + commission + swap if you hold overnight. For intraday trading the first two dominate; for positions held for days, all three do.
Commission is usually charged per lot and both ways (open + close) — the term "round turn" in a schedule signals this. You can see your trade size and its corresponding cost with our calculators before opening.
What to look for in a fee schedule
Looking only at trading commission is incomplete. Check whether the schedule states: deposit/withdrawal fees, inactivity fees, account maintenance fees and currency conversion margins. A firm publishing these openly is itself a transparency signal.
Transparency is one of the sub-axes of our FX Trust Score; you can compare how firms report imprint and fee information in the broker directory.
Warning sign: unexplained deductions
At a legitimate firm every deduction has a name and a written schedule. If unnamed amounts leave your account, or you are told to "pay a commission first to withdraw", the issue is not pricing — that is the most common pattern used to block withdrawals.
In that case, first verify whether the platform appears on the SPK-authorised list; which authority to approach and how is set out in our complaint guide.
