What Is Slippage?
When an order executes at a different price than expected; common during high volatility.
During news and low liquidity, orders can fill at a different price; brokers offering guaranteed stops reduce this risk.
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).

Why slippage happens
Slippage is when an order fills not at your expected price but at the first available one. The cause need not be bad faith: when liquidity drops or price moves fast, the level you saw may no longer exist by the time your order arrives.
The moments it appears most are predictable: major data releases, weekend gaps at the weekly open, and overnight sessions.
How it breaks your risk management
This is the real issue: a stop-loss does **not guarantee** your level — it executes at the first price after that level is crossed. So "my risk is capped at this much" may not hold in volatile markets.
Some firms offer guaranteed stops for an additional fee. Whether they are offered and under what conditions is set out in the contract; it is one of the clauses to read before opening an account.
Legitimate slippage or bad practice?
Slippage can go either way — sometimes it fills in your favour. A pattern that consistently works against you deserves scrutiny; the ECN/STP versus Market Maker question matters here, because in the latter the broker is the counterparty.
Two signals to check: whether the firm publishes a slippage policy, and how heavily complaints cluster on "order not filled / price slipped". Compare firms in the broker directory, or report your experience.
