A broker choosing between MT5 and cTrader is not really choosing a terminal. Both platforms hand a trader charts, an order ticket and an app to install, and both do that well. What differs is everything the broker still has to build around the platform afterward: the liquidity bridge, the CRM connection, the risk tooling, and whether traders already know the name before they open a demo account. The MT5 vs cTrader for brokers question is a question about what you are willing to assemble yourself.
MetaTrader 5, from MetaQuotes, carries the largest base of traders who already trade on it and the biggest library of robots and indicators through the MQL5 Market and community. cTrader, from Spotware, is built around Level II depth of market, a C# algorithmic environment called cTrader Algo, and a desktop a smaller but committed group of traders prefer. Neither platform ships with a CRM, a liquidity bridge or risk plugins. A broker adds that stack around either one.
The short version
| Factor | MT5 | cTrader |
|---|---|---|
| Made by | MetaQuotes | Spotware |
| Trader base and library | The largest base of traders and the biggest robot and indicator library, through MQL5 | A smaller base, with traders who specifically want Level II depth of market and C# automation |
| Depth of market | Included since MT5, alongside hedging and netting account modes | Level II depth of market on every account, a long-standing part of the pitch |
| Automation | MQL5, a huge script and robot library, a multi-threaded strategy tester | cTrader Algo in C#, which suits developers from a .NET background |
| Apps | Desktop, web, iOS, Android | Windows, Mac, web, iOS, Android |
| Copy trading | Signal services inside the platform | cTrader Copy, built into the platform |
| What a broker still adds | Bridge, CRM, price feed, risk plugins from other vendors | Bridge, CRM, price feed and risk tooling from other vendors |
MT5 vs cTrader for brokers: the licensing question
MetaQuotes decides who gets an MT5 licence and on what terms, and it enforces those terms. In early 2024, a number of prop firms had to change or add platforms at short notice after MetaQuotes tightened its licensing rules; many of the firms affected added DXtrade, Match-Trader, TradeLocker or cTrader alongside or instead of MetaTrader. Apple pulled both MetaTrader apps from the App Store in September 2022 and they only returned in March 2023, a five-month stretch where MetaTrader was simply unavailable to new iPhone users through the normal channel. Neither event was about a broker doing anything wrong. Both were reminders that when one vendor controls the terminal, its decisions become the broker's business risk.
cTrader carries less of that specific history because Spotware licenses far fewer brokers and its terms have not made industry headlines the same way. That is not the same as saying vendor risk disappears with cTrader. Any broker running a single platform from a single vendor is exposed to that vendor's roadmap, pricing and licensing decisions, whichever platform it is.
Liquidity and the bridge every broker still needs
Neither platform includes a price feed or a liquidity connection out of the box. A broker on MT5 or cTrader buys or builds a bridge to its liquidity provider, decides how orders route between A-book and B-book, and usually adds a separate risk management layer to watch exposure and toxic flow. This is standard industry structure, not a shortcoming unique to either vendor: a trader installs the platform's own app and picks the broker's server inside it, the way MT5 shows "BrokerName-Live" and cTrader shows the broker in its own list, and the broker's CRM opens accounts through the platform's API.
Where the two differ in practice is the size of the vendor ecosystem selling bridges and plugins. MT5's age and market size mean more third-party bridge, CRM and risk vendors build for it first. cTrader's ecosystem is smaller, though a broker with an established liquidity relationship and an existing risk stack will find integration work is comparable on either platform. Ask any prospective bridge or CRM vendor directly which platform they support natively before signing, since the answer shapes months of integration time either way.
Trader base and marketing pull
MT5 traders show up already knowing the platform. That matters most for a broker marketing to a broad retail audience, where "we run MT5" answers a question new clients ask before they ask anything else. cTrader's following is smaller and more specific: traders who care about Level II depth of market, a cleaner desktop, or building strategies in C#. A broker whose target audience already favours cTrader will convert that audience faster on cTrader than by trying to move them onto MT5, and the reverse is true for a broker chasing MT5's larger, more general base.
This is where the decision stops being purely technical. A broker's existing introducing-broker network, its affiliate relationships and the platform its competitors run all push toward one answer or the other before a single feature comparison happens.
The automation ecosystem: MQL5 vs cTrader Algo
MetaTrader 5 robots and indicators are written in MQL5, and the MQL5 Market and community hold the largest library of ready-made scripts in the industry. Traders who already depend on a specific MQL5 robot will often only trade where MT5 is offered, which is a real constraint on a broker considering dropping it. MT5 also adds a multi-threaded strategy tester, hedging and netting account modes, and more timeframes than MT4 offered.
cTrader Algo runs on C#, a mainstream language that suits developers from a .NET background more naturally than MQL5's own syntax does. Its library is smaller, but the traders who use it tend to be building custom strategies rather than downloading someone else's. cTrader Copy adds copy trading inside the platform itself. Neither ecosystem is objectively bigger in every sense: MT5 wins on volume of ready-made robots, cTrader wins on the familiarity of the language for a professional developer.
How to choose
If your target audience already trades MT5, or your growth depends on introducing brokers who bring MT5 clients, the licensing risk is a cost you accept for the reach. Budget for a bridge, a CRM connection and risk tooling from the start, and treat the platform relationship itself as something to actively manage rather than a set-and-forget vendor contract. If your audience is smaller and more specific, drawn by depth of market or C# automation, cTrader gets you that audience without competing for attention inside MetaTrader's much larger and more crowded distribution.
Most brokers that have been through a licensing scare end up running both, or running one of the two next to a platform that arrives with more built in. That is the practical case for a third option: eTrader bundles the price feed, the dealing desk, MAM / PAMM and copytrading with the platform itself, so a broker adding it is not assembling a bridge, a CRM connection and risk tooling from separate vendors the way it would for MT5 or cTrader. The honest trade-offs run the other way: eTrader is the newest of the three, its third-party library is far smaller than MQL5's, and robots are written in Tide, its own language, so an MQL5 or cTrader Algo strategy has to be rewritten rather than imported. For a broker that wants to test it, SGHK's liquidity bridge setup is one of the pieces already built in.
"Every broker running MT5 or cTrader alone is one licensing letter away from a hard conversation with its traders. The platforms that get chosen as a second option are the ones that arrive with less left to assemble."

Key Takeaways
- MT5 wins on trader base and the size of the MQL5 robot and indicator library; cTrader wins on Level II depth of market and a C# automation environment developers already know.
- Neither platform includes a bridge, a CRM or risk tooling; a broker assembles that stack around both of them in a similar way.
- The 2022 App Store removal and the 2024 licensing changes are the concrete reasons brokers now price vendor control into the decision alongside features.
- eTrader is a third option that bundles the feed, dealing desk, MAM / PAMM and copytrading, at the cost of being the newest platform with the smallest third-party library of the three.
Frequently Asked Questions
Is cTrader cheaper for a broker to run than MT5?
Licence terms and fees are set individually by each vendor and change over time, so ask MetaQuotes and Spotware directly for current terms rather than relying on a published figure. The bigger cost difference in practice is integration: both platforms need a bridge, a CRM connection and risk tooling built or bought separately.
Do MT5 and cTrader both support A-book and B-book routing?
Routing logic is not built into either platform. A broker adds a bridge and a risk management layer that decides how client orders split between the liquidity provider and the house book. That routing layer, not the trading platform itself, is what runs A-book, B-book or hybrid rules.
Can a broker run MT5 and cTrader at the same time?
Yes, and many do, usually after a licensing scare on one platform convinces them not to depend on a single vendor. Running both means maintaining two bridges, two sets of account groups and two risk setups unless the CRM connects to both.
What does eTrader add that MT5 and cTrader do not include?
eTrader arrives with its own price feed, a built-in dealing desk with hybrid routing, native MAM / PAMM and copytrading, and cloud-hosted robots, so a broker is not sourcing a feed or a bridge separately. It is the newest of the three platforms, its third-party library is smaller, and robots are written in Tide rather than MQL5 or C#.
