MT4 vs MT5 for Funded Forex Traders

TL;DR: MT4 (2005) is forex-only with 9 timeframes, 4 pending order types (buy limit, sell limit, buy stop, sell stop), hedging-only accounts, MQL4, no depth of market, and no economic calendar. MT5 (2010) is multi-asset with 21 timeframes, 6 pending order types (adds buy stop limit and sell stop limit), hedging or netting, object-oriented MQL5, built-in depth of market and economic calendar, a multi-currency strategy tester, and CFDs on forex, metals, energies, indices, stocks, and futures. MetaQuotes no longer issues new MT4 licenses, most prop firms run evaluations on MT5 only, and MQL4 tools do not run on MT5 without a rewrite. For a trader whose funded account ends on a daily loss limit or max drawdown breach, MT5 is the platform to learn.

You are about to pay for an evaluation, and the firm gives you one platform choice or none at all. If you spent two years on MT4, the real question is not "which platform is better." It is "what could a platform difference cost me on an account that ends the moment I break a rule."

Retail comparisons weigh chart aesthetics. A funded trader has to weigh whether a netting account will silently close a hedge, and whether a news release they did not see will push them through a daily loss limit.

What MT4 and MT5 Are

MetaTrader 4 was released by MetaQuotes in 2005 for one job: spot forex through a broker's server. It runs indicators and Expert Advisors (EAs) written in MQL4, and for more than a decade it was the default at most forex brokers.

MetaTrader 5 followed in 2010 as a multi-asset platform built to connect to exchanges as well as forex liquidity, which is why it carries a depth of market window, exchange-style order types, and a netting mode. MetaQuotes has focused development on MT5 since and stopped issuing new MT4 licenses to brokers.

MT4 still works where it is already installed, but when a prop firm says "MT5 only," that is often the only license it can get.

MT4 vs MT5 Feature Comparison Table

Indicator counts vary by build. The structural differences (pending orders, netting, MQL5, DOM, calendar) are the ones that change how you trade.

Key MT4 vs MT5 Differences on a Funded Account

The useful question is which extras protect an account with a daily loss limit and a max drawdown.

Pending Orders and Fill Policies on MT5

MT4 gives you four pending orders. If you want to buy a breakout only after price pulls back into the broken level, no single order does that.

MT5 adds buy stop limit and sell stop limit. Example: EUR/USD is at 1.0850, resistance sits at 1.0870, and your plan is to buy the retest at 1.0862 only after the break. A buy stop limit with the stop at 1.0871 and the limit at 1.0862 does that without you watching the candle. The alternative, market-buying the breakout candle at 1.0875 out of fear of missing it, is the chase that becomes a 20-pip loss on 0.5 lots (about 100 USD at 5 USD per pip) before the retest happens.

Fill policies work in the other direction. A Fill or Kill order fills completely or not at all, so you do not end up with 0.3 lots of a 0.5-lot idea during a fast release, then add the rest at a worse price.

Hedging vs Netting on MT5

MT4 is hedging only: long 0.5 lots and short 0.3 lots of GBP/USD at once, as two tickets. MT5 supports hedging or netting. A netting account keeps one position per symbol: long 0.5, sell 0.3, and you are now long 0.2.

Here is where funded traders get caught. A trader may have used a hedge on MT4 to "lock in" a loss while waiting for direction. On a netting account that order closes part of the position instead, realizing the loss immediately against the daily loss limit. Check the account mode before you place a single order. Most MT4 hedging habits were ways of avoiding a stop anyway.

MQL4 vs MQL5 on MT5

MQL4 code does not run on MT5. A custom indicator or EA written for MT4 needs a rewrite in MQL5, which is object-oriented and stricter about types.

The upside is the tester. MT5 backtests across multiple symbols with real tick data. For a trader deciding whether an EA can stay inside a max drawdown over a meaningful sample, that is the receipt MT4 could never give you.

The failure mode: over-optimization. A curve-fit EA showing 2% max drawdown in the tester can still breach a funded limit in its first week. Test out-of-sample before trusting the number. Then read the firm's rules before running any EA on an evaluation or funded account: many allow only EAs you wrote yourself, can ask for the source code, and ban off-the-shelf EAs and third-party signal bots outright.

MT4 Pros and Cons

MT4 pros:

• Familiar to almost every forex trader, with tutorials everywhere.
• The largest library of free indicators, scripts, and EAs.
• Lighter on system resources, which helps on cheap VPS plans.
• Simple layout with few settings to break.

MT4 cons:

• Four pending order types and no fill policies.
• Single-currency strategy tester.
• No built-in calendar, so news risk depends on a browser tab you may forget.
• No depth of market.
• No new licenses from MetaQuotes, so fewer prop firms offer it each year.

Learning a platform your next firm may not support is study time you cannot get back.

MT5 Pros and Cons

MT5 pros:

• 21 timeframes, including H2, H6, H8, and H12 for session-based structure.
• Six pending order types plus fill policies for precise entries.
• Built-in economic calendar and depth of market.
• Multi-currency, real-tick strategy tester.
• One terminal for forex, metals, indices, and energies.
• Actively developed and the platform most new prop firms license.

MT5 cons:

• MQL4 tools do not transfer.
• More menus and account modes, so more places for a beginner to misconfigure something.
• Netting mode surprises MT4 traders.
• Smaller free indicator library.

None of these are reasons to avoid MT5. They are reasons to spend a week on a demo before an evaluation clock starts.
