For traders evaluating a forex or CFD prop firm in 2026, the platform question matters more than most newcomers realize. The platform decides how your orders are routed, what spread you're paying, what automation you can layer on, and, critically, whether you can run the same strategy across multiple firms at once. MT4, MT5, and cTrader are the three platforms that cover essentially the entire forex prop firm market, and each one optimizes for a different trader profile.
TL;DR: quick verdict
For most forex traders: MT4. Universal prop firm support, biggest EA ecosystem, lowest friction. For multi-asset / quant-friendly setups: MT5. For tight-spread scalping or institutional-feel execution: cTrader. If you trade across multiple firms, you'll likely end up running 2 of the 3. Make sure your copy trader handles all three natively.
MT4: the legacy standard
MetaTrader 4 has been the dominant retail forex platform since its 2005 release. MetaQuotes officially deprecated new licenses in 2016 but the existing footprint refuses to retire: there are still millions of active MT4 accounts across hundreds of forex brokers. The reason is straightforward: 15+ years of accumulated EAs (Expert Advisors / automated strategies), indicators, and broker integrations created a network effect that MT5 hasn't broken.
What MT4 does well. The universal default. Every forex prop firm of any size supports MT4 alongside their other platforms. The MQL4 language is the most-documented retail trading scripting language in existence: copy-paste solutions exist for almost every algorithm you'd want to implement. EA marketplaces (MQL5.com despite the version mismatch in the name) host tens of thousands of pre-built strategies.
What MT4 doesn't. It's a forex-and-CFD-only platform: futures, equities, and crypto are awkward at best. Single-thread architecture means a busy day can lag the UI. The MQL4 language is dated; threading and modern data structures aren't first-class. No native depth-of-market display. Stock and futures prop firms don't use it.
Who picks MT4 in 2026. Forex traders running EAs they already trust. Traders at prop firms that don't offer MT5 (some still don't). Anyone whose existing strategy library is MQL4-coded and migrating would be expensive.

MT5: the modern successor
MetaTrader 5, released in 2010, is what MetaQuotes wishes everyone had migrated to. It's a genuinely better platform than MT4 in almost every technical dimension: multi-asset support (forex, CFD, futures, equities), native depth-of-market, partial-close orders, hedging mode AND netting mode, multi-threaded architecture, MQL5 with proper object-oriented programming, native Python integration. If you were designing a retail trading platform from scratch in 2024, you'd build something close to MT5.
What MT5 does well. Multi-asset is the killer feature: one platform, one account, one EA framework across forex/CFD/futures/equities. The MQL5 language is genuinely modern; Python interop opens up the ML/quant world to retail. Order types and execution modes are far more flexible than MT4. Performance is meaningfully better on busy days.
What MT5 doesn't. Smaller third-party ecosystem than MT4 (still huge, just smaller). MQL5 is NOT backwards-compatible with MQL4: porting an MT4 EA to MT5 is a real engineering project, not a recompile. Some prop firms still default to MT4 for forex even when they technically support MT5.
Who picks MT5 in 2026. New traders without legacy MT4 strategies. Traders who want one platform across multiple asset classes. Quants who want Python integration. Anyone whose prop firm has fully embraced MT5 as the primary platform.
See our MT5 Trade Copier page for the integration details.
cTrader: the institutional option
cTrader is Spotware's challenger platform, released in 2010, redesigned several times, positioned as the "professional trader's MetaTrader alternative." Where MT4/MT5 use a market-maker-style execution model (broker quotes you a price, you trade against the broker's book), cTrader uses an ECN-style model (your order goes into a real depth-of-market book with multiple liquidity providers). The execution model alone changes the trading experience significantly.
What cTrader does well. Native depth-of-market for every instrument. ECN execution model with tighter spreads than typical MT4 brokers. cAlgo (the cTrader scripting language) is C#-based and modern. Cloud-native: the chart and order interface run as a web app, so there's no Windows-only install. cTrader Copy (the built-in copy trading service) works natively without third-party bridges if you stay in the cTrader ecosystem.
What cTrader doesn't. Smaller broker network than MT4/MT5. Fewer prop firms support it as the primary platform, typically a secondary option for "advanced" traders. The cAlgo library has way fewer pre-built strategies than MQL5.com. If you want copy-paste EAs from forums, cTrader has the smallest catalog.
Who picks cTrader in 2026. Scalpers and high-frequency retail traders who care about ECN execution and tight spreads. Traders coming from institutional backgrounds who want a familiar depth-of-market display. Anyone whose prop firm pushes cTrader as the primary platform (Fintokei, FunderPro, FundingPips, FXIFY all have strong cTrader support).

Which prop firms use which platform
Platform availability varies firm-by-firm and changes regularly. The current landscape (mid-2026):
- MT4 + MT5 + cTrader (all three): FTMO, Fintokei, FunderPro, FundingPips, E8 Markets, FXIFY
- MT4 + MT5 only: MyFundedFX, FundedNext, The Funded Trader, Funded Trading Plus, Alpha Capital Group, BrightFunded, Hola Prime, The Trading Pit, The 5%ers
- MT5 only (no MT4): Darwinex Zero (intentional MT5-first positioning)
- cTrader-first or cTrader-only: Rare among prop firms but growing: a handful of newer institutional-style firms
If you trade across multiple firms, which most serious prop traders do for risk diversification, you'll typically end up with accounts on at least two of the three platforms. That's where a multi-platform copy trader earns its keep.
The platform you pick first is usually the one your first prop firm offers. The platform you end up on is whichever lets you run your strategy across the most firms simultaneously.
Which one should you pick
Pick MT4 if:
- You're new to forex prop firm trading: universal compatibility removes friction
- You already have MQL4 EAs you trust
- Your strategy is discretionary and you don't need depth-of-market
- You want the biggest available pool of pre-built indicators and templates
Pick MT5 if:
- You want to trade multiple asset classes (forex + CFD + futures + stocks) in one platform
- You're a quant / use Python for analysis or ML
- You need partial-close orders, native depth-of-market, or hedging-and-netting modes
- You're starting fresh with no MT4 legacy
Pick cTrader if:
- You scalp tight spreads and need ECN-style execution
- You want C#-based scripting (cAlgo) instead of MQL
- Your prop firm makes cTrader the primary platform
- You value execution transparency over EA ecosystem breadth
The right architectural answer for most multi-firm prop traders is: have accounts on MT4 + MT5 + cTrader simultaneously, run one master strategy, copy it across all three with a copier that handles all three natively. Thor handles MT4, MT5, and cTrader (plus DXTrade) in a single configuration at $39/month flat: you place one trade, every forex/CFD prop firm account fires it.
For the technical specifications of each platform, see MetaQuotes for MT4/MT5 and Spotware for cTrader. For the regulatory framework around copy trading services in the US, see the National Futures Association.
Frequently asked questions
Is MT5 better than MT4 for prop firm trading?
It depends on the firm. MT5 is technically the modern successor: multi-asset, native depth-of-market, partial-close orders, Python-friendly. But MT4 remains the global standard among forex prop firms. If your prop firm offers both, MT5 is the better long-term choice; if they only offer MT4, that's not a deal-breaker.
Which forex prop firms use cTrader?
cTrader is supported as a primary or secondary platform by FTMO, Fintokei, FunderPro, FundingPips, E8 Markets, FXIFY, and a growing list of newer firms targeting institutional-style execution.
Can I copy trades between MT4 and MT5?
Yes, with a trade copier that supports both platforms natively. The two are different protocols, so the copier needs separate integrations. Thor supports MT4 and MT5 natively in a single configuration, so a master account on MT4 can copy to a follower on MT5 (or vice versa) without manual bridging.
Why is MT4 still around if MT5 is technically better?
Network effects. MT4 has 15+ years of accumulated retail trader habits, EAs, indicators, and broker integrations. Most forex prop firms support MT4 because that's what their traders demand. MetaQuotes has tried to deprecate MT4 multiple times since 2016 but the user base refuses to migrate. Expect MT4 to remain dominant in forex retail through at least 2027.
Which platform has the lowest execution latency?
Execution latency depends more on the broker's infrastructure than the platform itself. cTrader generally has lower latency in benchmark tests because Spotware operates the cloud servers directly and uses a more efficient FIX-based protocol. MT4 and MT5 latency varies wildly broker-by-broker.
