What Is Liquidity?
How quickly an asset can be bought/sold without significantly moving its price. Low liquidity increases slippage.
High liquidity brings tight spreads and fast execution; exotic pairs and session closes are low-liquidity.
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).

What does liquidity look like in practice?
Liquidity is how quickly an asset can be bought or sold without moving its price meaningfully. In forex you feel it in three places: whether the spread widens, whether your order fills at the price you wanted, and whether there is a counterparty when you want to close.
Majors like EUR/USD are highly liquid for most of the day. On exotics such as USD/TRY and around session closes, liquidity falls; the same order at the same size fills at a worse price.
What happens when liquidity drops?
Two concrete effects: spreads widen and slippage increases. Slippage is when an order fills not at your expected price but at the first available one. Around news, at the weekly open and in overnight sessions, the two appear together.
Your stop order is affected too: a stop-loss may trigger not at your level but at the first available price beyond it. So the assumption "I capped my risk at 100 lira" may not hold in thin liquidity.
How do you read liquidity when choosing a broker?
Liquidity is a market property, but how a broker accesses it differs by firm. In an ECN/STP model the broker routes orders to liquidity providers; in a Market Maker model the broker is the counterparty. In the latter, how prices are formed and how conflicts of interest are managed matters more.
Concrete things to check: whether the firm states its execution model in its imprint, whether a slippage policy is published, and how heavily complaints cluster around "order not filled / price slipped". You can compare how firms report this in our broker directory.
Is low liquidity a fraud signal?
Not on its own — it is a market condition that occurs at legitimate firms too. But on unauthorised platforms, "there is no liquidity" can be a cover story for a market that does not actually exist: if it comes alongside a growing profit screen and permanently delayed withdrawals, the issue is not liquidity.
One question settles it: is the platform on the list of SPK-authorised institutions? If it is, margins are reported to the central clearing bank and there is an authority to turn to. If not, the problem is authorisation rather than liquidity — what to do is in our complaint guide.
