Question: Who are the Liquidity Providers(Market Maker) on cTrader trading platform?
It depends on your broker.
As cTrader trading platform is solely a platform to connect traders and financial markets, the platform itself doesn’t provide any liquidity or price feeds.
But the market liquidity comes from your broker or the connected Liquidity Providers.
You need to contact your broker to find out where your orders will be executed, as in who are the liquidity providers for the trading platform you are using.
