Is a more expensive EA automatically better?

No — and this is the most important caveat about the tier framework. Price and quality are correlated on average but not in every individual case. A $499 EA from an unknown developer with no live track record is worse than a $149 EA from a developer with 18 months of verified Myfxbook results and active community support. The framework above describes what to expect within each tier statistically — individual exceptions exist at every price point, in both directions.

Can a free EA ever be worth using on a live account?

Yes, but the bar is the same as for any paid EA: you need a verified live track record, a transparent strategy, and active developer support. Free EAs meeting all three criteria exist — they are rare but not non-existent. The more common pattern is free EAs meeting zero of the three criteria. If a free EA passes your due diligence checklist, there is no logical reason not to use it. The challenge is that the due diligence process itself takes time and expertise that most retail traders do not have.

What does the MQL5 marketplace actually cost developers to list on?

MQL5 takes 30% of the sale price on marketplace listings. A developer selling a $299 EA receives approximately $209 per sale. For an individual developer spending 3–6 months building and testing a strategy, plus ongoing support and updates, a $299 sale price needs several hundred sales to become economically viable. This is why serious developers at this price point either price higher or rely on volume — and why the $20–$99 tier often features mass-produced products where the economics only work at high volume with minimal support overhead.

How much should I budget for an EA relative to my account size?

A reasonable framework: at conservative risk tolerance, EA cost should not exceed 2% of your trading account. At moderate, 5%. At aggressive, 8%. On a $5,000 account at moderate tolerance, a $250 EA is reasonable. On a $1,000 account, a $50 EA is the sensible ceiling. This is not about the EA quality available at that price — it is about alignment between your risk framework and your expectations. An expensive EA on a small account creates psychological pressure to "make it work" that distorts risk management decisions.

What is the total cost of ownership of a trading EA?

Beyond the EA purchase price: a VPS (Virtual Private Server) for 24/5 operation costs $20–$50/month. Your broker's ECN commission on a gold EA running 10 trades/day at 0.1 lot is typically $3–$7/day, or $60–$140/month. Spread costs on gold at 8–12 pips per trade at 0.1 lot are $8–$12/trade. For a high-frequency gold EA, the annual overhead beyond the EA purchase can easily reach $2,000–$3,000 in execution costs plus VPS. This context makes the EA price itself relatively minor in the total cost calculation.

How do I verify a track record if I am not sure what to look for?

Five non-negotiable checks: (1) Is the Myfxbook account set to real money — not demo? Demo results are meaningless. (2) Is the account at a broker you recognise — or an offshore broker that might not enforce fair execution? (3) Is the account age at least 6 months? Anything shorter is a cherry-picked start date. (4) Is the drawdown disclosed and reasonable — under 30% for a typical strategy? (5) Has the account been reset or closed during the period shown? Resets are visible if the account history is full rather than filtered. Any EA that fails two or more of these is not ready for your real money.

Should I buy from MQL5 or directly from a developer's website?

Both have trade-offs. MQL5 offers buyer protection through its review system and seller accountability requirements. A direct purchase from a developer's website can offer better support and direct communication but has no platform-level protection if the EA turns out to be misrepresented. For your first EA purchase, MQL5 is safer. For subsequent purchases from developers you have already vetted, direct purchase may offer better pricing and support. Never purchase from Telegram groups, Discord servers, or social media unless you have independently verified the developer is the same person as the MQL5 listing.

What Development Actually Costs — And Why It Explains Price Tiers

An EA is not just code — it is code plus research plus infrastructure plus support. Understanding what each component costs explains why the pricing tiers exist in the first place.

Strategy research

40–80 hours

Identifying a genuine edge in historical data, validating it is not over-fitted, developing the logic that will become the EA rules.

MQL5 development

20–60 hours

Writing the code, handling edge cases, implementing risk management, parameter structure, and error handling.

Tick-data backtesting

$50–$200 in server costs

Running 99% quality backtests over 3+ years of data requires server resources, particularly for high-frequency gold strategies with thousands of trades.

Forward testing period

3–6 months of time

Out-of-sample validation on a live or demo account. This is time the developer cannot monetise the EA. It represents opportunity cost.

Ongoing support

2–5 hours/week

Responding to user questions, updating for broker or platform changes, monitoring for strategy degradation in changing market conditions.

MQL5 marketplace fee

30% of each sale

MQL5 retains 30% of every transaction. A $199 EA nets the developer $139 per sale before time and infrastructure costs.

The implication: a properly developed EA with research, backtesting, forward testing, and the first year of support easily represents 200+ developer hours before a single sale. At a consulting rate of $50–$100/hour, the break-even on development costs for a $199 EA requires 140–300 sales. Most EA listings never reach this volume. Free EAs, by definition, must recoup costs through a different mechanism — which is why the "free EA as generosity" framing is almost always inaccurate.

The MQL5 Marketplace Reality: 18,000+ EAs and What That Actually Means

MQL5's marketplace had over 18,000 Expert Advisors listed as of 2025. This number sounds like abundance. In practice, it is a signal-to-noise problem. Analysis of the marketplace reveals:

~85% have no verified live trading record of any kind. Their marketing material is backtests, screenshots of backtests, or statements about future performance.
Average time since last update: 14 months. Most EAs on the marketplace are effectively abandoned. The developer published, received a few sales, then moved on.
Review manipulation is widespread. New accounts posting immediate 5-star reviews, groups of reviews all appearing within the same 48-hour window, and responses to critical reviews that attack the reviewer rather than address the criticism are all common patterns.
Backtest cherry-picking is the norm, not the exception. A backtest covering only 2020–2021 (gold bull market) will show any long-only gold EA looking exceptional. The same EA run on 2022 (Fed rate hike cycle, gold declining) would show very different results.

The free scalping bot comparison specifically — how free vs paid plays out for scalping instruments — is in our scalping bot cost guide. The verification framework that applies across all tiers starts with the five non-negotiable checks in the next section.

The 5 Non-Negotiable Verification Checks for Any EA

These five checks apply equally to a $0 free EA and a $999 professional system. An EA that fails any of them requires a compelling explanation before it earns real money.

01

Live real-money track record

Ask for a Myfxbook or equivalent link. Verify: is it real money (not demo)? Is the account at a recognisable broker? Is the history complete (not filtered)? Is it at least 6 months old?

02

Strategy description in plain language

The developer should be able to explain in 3 sentences: what signal generates the entry, what filter prevents bad entries, and what exit logic closes the trade. "Proprietary algorithm" without further detail is not an acceptable answer.

03

Backtest with realistic conditions

Backtest must cover at minimum 2020–2023 (different market regimes). Spread should match real ECN spread for the instrument. Backtest on MT5 with tick data is the gold standard — MT4 90% modelling quality backtests are insufficient for strategy validation.

04

Active developer

When did the EA last receive an update? Is there a public changelog? Can you contact the developer and get a response within 48 hours before purchasing? An inactive developer means an orphaned EA.

05

No guaranteed return claims

Any EA claiming a guaranteed return, "99% win rate," or specific monthly profit percentage is either dishonest or operating a martingale/high-risk system that will eventually blow the account. These claims are regulatorily unacceptable and practically dishonest.

The Lifecycle Comparison: Free vs Paid EA Longevity

Free EAs have an average lifespan of 8–14 months from publication to effective abandonment. This is based on the average time-since-last-update for free MQL5 listings and the observable pattern of developer attention. Paid EAs at the mid-range and professional tiers show significantly longer active development windows — typically 24–36+ months for EAs with established user bases that generate ongoing sales to fund support.

The practical consequence is that a free EA you start using today may have no broker-compatibility update in 12 months when your broker changes their execution model. It may have no fix when MetaTrader releases a platform update that breaks a specific API call the EA relies on. Paid EAs at reputable developers are maintained because failing to maintain them means losing future sales and reputation.

The total cost of ownership concept matters here: an EA that cost $0 but produced losing trades for 8 months before being abandoned has a very different — and typically much higher — real cost than a $299 EA with 3 years of active development and a verified profitable track record.

When to Build vs Buy at Each Price Tier

Building your own EA versus buying one is a question of comparative advantage. If you have MQL5 development skills, the time to build, and the capacity to run forward testing — building gives you complete strategy transparency and zero ongoing licensing cost. But most retail traders do not have all three. For them, buying is more efficient.

Situation	Recommendation	Why
You have MQL5 skills + 200+ hours	Build or heavily customise	Full transparency, no licensing fees, complete control over updates
You want to test a strategy concept	Budget tier ($20–$99) or free	Low capital risk during validation. Do not scale with a tier-1 or 2 EA.
You are ready for real money on a $3,000–$10,000 account	Mid-range ($100–$399)	Verified track record, adequate support, sensible budget relative to account
You have $15,000+ and need institutional reliability	Professional ($500+)	Non-negotiable track record standards, active support, ongoing research
You have an existing profitable manual strategy	Build or commission a custom EA	Pre-existing edge justifies custom development rather than adapting to someone else's strategy
