Comparison

QuantParadox vs MetaTrader 5

MetaTrader's tester is free, broker-native and runs the exact code you will trade. Here is where that is enough, and where it is not.

What MetaTrader 5 is

The MetaTrader 5 Strategy Tester is a backtesting and optimisation module built into the free MT5 terminal, for testing Expert Advisors written in MQL5 before trading them live.

The short answer

MT5's tester is free and closes the gap between what you test and what you trade, because it runs the same MQL5 code against your own broker's prices. That is a real advantage we cannot match. What it does not give you is history you can trust to be consistent, a rolling walk-forward, or a way in without learning MQL5.

When MetaTrader 5 is the better choice

Written without hedging, because a comparison page that cannot name a reason to pick the other product is an advertisement wearing a lab coat.

It is free, permanently

No licence, no subscription, no tier. For a great many traders that settles the question, and it should.

Broker-native, so the test matches the account

It runs against the prices, spreads and execution model of the broker you actually trade with. A cloud platform modelling a generic market cannot reproduce your broker's behaviour, and we do not pretend to.

Real tick data, where your broker has kept it

The 'every tick based on real ticks' mode uses ticks accumulated by the broker rather than simulating them — the highest-fidelity option available anywhere at zero cost.

Nothing is translated on the way to live

The MQL5 you tested is the MQL5 that trades. Every platform that exports code — ours included — carries some translation risk that MT5 simply does not have.

Where QuantParadox is the better tool

History that does not depend on which broker you opened an account with

MT5 downloads its bars and ticks from your trading server, so depth and quality vary by broker and there is no guaranteed number of years. We run every test against one fixed ten-year archive, so two runs a month apart are comparable.

No MQL5 to learn

Building or changing a strategy in MT5 means writing MQL5. Here you describe the rules or draw them, and you can export working MQL5 at the end.

Rolling walk-forward, not one split

MT5's optimiser offers a single forward-testing period — a half, third or quarter of the range held back. That is a real and useful control, and it is one split. Our grading walks the strategy through unseen history and reports where it held and where it decayed.

The rough modelling modes cannot flatter you here

MetaQuotes documents that '1 minute OHLC' builds a fixed synthetic path from four prices per minute, and warns that stop levels in 'open prices only' may trigger at a different price than specified. Their own advice is to re-test anything that looks too good on every tick. There is no fast-but-optimistic mode here to be caught by.

Bar holding both stop and targetDepends on the modelling mode. 'Every tick based on real ticks' uses the broker's recorded sequence. '1 minute OHLC' builds a fixed synthetic path from four prices a minute, so the ordering is a construction rather than a record.Measured, not assumed. We walk the finer bars inside that bar and take whichever level was touched first. Where the finer data does not cover that bar, we book the loss — never the win.
Out-of-sample / walk-forwardA single forward-testing split in the optimiser — none, half, a third, a quarter or a custom date. Rolling walk-forward needs third-party tooling.Built in and unavoidable. Every verdict is graded on a recent stretch of history the strategy was never fitted on, and the engine rejects far more strategies than it passes.

Questions people actually ask

Is the MetaTrader 5 Strategy Tester good enough on its own?

For testing an Expert Advisor against your own broker's prices, it is genuinely strong and it is free. Its weak points are that history quality depends on your broker, its faster modelling modes build a synthetic price path inside each bar, and it offers one forward-testing split rather than a rolling walk-forward.

What is the difference between MT5's modelling modes?

'Every tick based on real ticks' replays ticks the broker actually recorded. 'Every tick' simulates ticks between each bar's four prices. '1 minute OHLC' uses only those four prices a minute, producing a fixed path. 'Open prices only' is fastest and roughest — MetaQuotes warns stop levels may trigger at prices other than specified.

Can I use both MT5 and QuantParadox?

That is the common pattern. Validate here against a fixed ten-year archive with out-of-sample grading, export working MQL5, then run it in MT5 against your own broker to confirm it behaves on their prices before arming anything.

Does QuantParadox place live trades like MetaTrader?

No. We are a research and validation platform, not a broker or a terminal. You export the finished strategy as MQL5, Pine, Python or LEAN and run it yourself. Live trading stays off unless you arm it, on your own account.

The only comparison that settles it is your own strategy.
