How I Tested MT5 for Spread Betting
This is a niche within a niche, so my testing methodology was focused specifically on MT5 performance rather than general broker quality.
Testing period: February 2026 — three full weeks of live testing on funded spread betting accounts with both Pepperstone and IG.
What I tested:
- MT5 platform stability: Ran MT5 continuously during London and New York sessions, monitoring for disconnections, requotes, and lag. Pepperstone’s MT5 dropped once (scheduled maintenance). IG’s MT5 had zero unexpected disconnections.
- Expert Advisor execution: Ran the same MQL5 EA (moving average crossover on GBP/USD, 3–5 trades/day) on both platforms over two weeks. Pepperstone’s Razor filled within 1–2ms. IG was slightly slower but within acceptable parameters.
- Depth of market: Pepperstone showed meaningful liquidity depth on major pairs during London session. IG’s DoM was more limited in granularity, though still functional.
- MQL5 indicator compatibility: Installed 12 custom indicators from the MQL5 marketplace. All 12 loaded on Pepperstone. 11 of 12 worked on IG — one required a symbol naming adjustment.
- Spread monitoring: Logged spreads every 30 minutes during London sessions. Pepperstone Razor averaged 0.12 pips on EUR/USD. IG averaged 0.82 pips.
| Category | Weight |
|---|---|
| Fees (spreads + commissions) | 25% |
| Platform (MT5 implementation quality) | 20% |
| Assets (markets available via MT5 SB) | 15% |
| Mobile (MT5 mobile app experience) | 15% |
| Tools (MT5-specific: EAs, DoM, MQL5) | 10% |
| Support (MT5-specific help quality) | 10% |
| Regulation (FCA status, FSCS) | 5% |

Pepperstone — Best MT5 Broker for Spread Betting Overall
Pros
- Tightest MT5 spreads for spread betting (EUR/USD from 0.1 pips on Razor)
- Only UK broker offering MT5 + cTrader + TradingView all for spread betting
- Strong EA execution — consistent 1–2ms fills in my testing
- Hedging mode fully supported on MT5 spread bet account
- No minimum deposit requirement (£200 recommended)
- Full MQL5 marketplace compatibility
Cons
- 2,700+ markets — significantly fewer than IG’s 17,000+
- Razor account commission (£2.25 per lot per side) adds up for high-frequency traders
- No full proprietary desktop platform — relies primarily on third-party platforms
- Standard account spreads (from 1.1 pips EUR/USD) are wider than IG’s default
Our Review
Pepperstone is the standout choice for MT5 spread betting in the UK. It is the only FCA-regulated broker where I can use MT5, cTrader, and TradingView — all for spread betting on the same account. Read our full Pepperstone review for a broader assessment beyond MT5.
Pepperstone’s MT5 implementation for spread betting feels native. The platform loads spread bet instruments with proper GBP-per-point notation rather than the contract-size formatting I have seen on some CFD-only MT5 setups. Chart data is clean across all 21 timeframes, and the one-click trading panel works identically to the CFD version.
During my February 2026 testing, I ran a trend-following EA on the FTSE 100 spread bet market. The EA placed 47 trades over two weeks. Slippage was negligible — 41 fills at the requested price, 4 with positive slippage, 2 with negative slippage of less than 0.5 points. That is strong execution for spread betting on MT5.
Cost breakdown
The Razor account offers raw spreads from 0.1 pips on EUR/USD with a £2.25 per lot per side commission (£4.50 round trip). The Standard account marks up spreads to include commission (EUR/USD from 1.1 pips, zero commission). For a trader placing 10 standard lots per month on EUR/USD, the Razor account works out cheaper — the break-even point is roughly any volume above 2–3 lots per month.
Who is Pepperstone’s MT5 best for? Traders who want to run automated strategies on a tax-efficient UK spread bet account. It is also the best fit for anyone who wants the flexibility to switch between MT5, cTrader, and TradingView without leaving a spread betting wrapper. I would be less inclined to recommend it for traders who need access to niche markets — IG covers far more ground there.
Key Details
| Best for | EA traders, multi-platform spread bettors, cost-focused users |
| Not ideal for | Traders needing niche markets, those wanting a heritage brand |
| EUR/USD spread | From 0.1 pips (Razor) / 1.1 pips (Standard) |
| GBP/USD spread | From 0.2 pips (Razor) / 1.2 pips (Standard) |
| Gold spread | From 0.15 points (Razor) |
| Commission | £2.25/lot per side (Razor) / £0 (Standard) |
| Minimum deposit | £0 (£200 recommended) |
| Total markets | 2,700+ |
| Platforms (all for SB) | MT5, MT4, cTrader, TradingView |
| FCA FRN | 684312 |
| FSCS Protection | £85,000 |
| My testing verdict | 1–2ms EA fills; 47 trades with negligible slippage; best MT5 DoM data of the two |

IG — Best MT5 Broker for Market Range
Pros
- 17,000+ markets available via spread betting — the widest range of any MT5 spread betting broker
- FTSE 250 listed — publicly audited financial statements
- Founded 1974 — longest operating history of any UK spread betting broker
- Spread-only pricing on most markets (no commission complexity)
- ProRealTime access alongside MT5 for advanced charting
- Zero unexpected MT5 disconnections during my three-week test
Cons
- EUR/USD spread from 0.6 pips — wider than Pepperstone Razor’s 0.1 pips
- No cTrader option for spread betting
- MT5 depth of market less granular than Pepperstone’s in testing
- One custom MQL5 indicator required symbol name adjustment to work
- No raw spread + commission account option
Our Review
IG is the heritage choice. Founded in 1974, listed on the FTSE 250, and regulated by the FCA since the register existed, it offers a level of institutional credibility that few brokers can match. The MT5 spread betting integration gives access to over 17,000 markets — more than six times Pepperstone’s range.
IG’s MT5 for spread betting works reliably. The platform pulls in IG’s full spread bet instrument list, and the sheer number of available markets is immediately noticeable. I could spread bet on individual US stocks, niche indices, and commodities that simply are not available on Pepperstone’s MT5.
Running the same moving average EA that I tested on Pepperstone, IG’s fills were slightly slower — averaging 3–5ms versus Pepperstone’s 1–2ms — but still well within acceptable bounds. I did not experience any requotes during the testing period.
Where IG falls behind is in the depth of market display. While it technically supports the feature, the Level 2 data felt less detailed than Pepperstone’s during the London open. For most retail spread bettors this will not matter, but for traders using order flow analysis alongside their EAs, it is worth noting.
Who is IG’s MT5 best for? Traders who prioritise market access over raw spread tightness. If the trading approach involves spread betting across equities, commodities, forex, and indices — and the goal is to do it all from MT5 — IG is the more versatile choice. I would also point traders who value institutional stability toward IG. Being FTSE 250-listed with nearly 50 years of operating history provides a layer of reassurance that a privately held broker cannot replicate.

What Is MetaTrader 5?
MetaTrader 5 (MT5) is a multi-asset trading platform developed by MetaQuotes Software, released in 2010 as the successor to MetaTrader 4 (MT4). Despite being over 15 years old, MT5 remains one of the most technically capable retail trading platforms available. For a wider look at the best MT5 brokers in the UK, see our dedicated guide.
Key features include 21 timeframes (compared to MT4’s 9), the MQL5 programming language supporting object-oriented programming for expert advisors and custom indicators, depth of market (Level 2 order book data), a built-in economic calendar, multi-asset support, netting and hedging modes, a multi-threaded strategy tester for faster backtesting, and the MQL5 community marketplace with thousands of indicators and EAs.
MT5 was originally designed for exchange-traded markets (stocks, futures), which is why it includes features like the economic calendar and depth of market that MT4 lacks. MetaQuotes has officially stopped licensing MT4 to new brokers, pushing the industry toward MT5 adoption.
Which MT5 Features Matter Most for Spread Betting?
Not every MT5 feature is equally relevant to UK spread bettors. Here are the ones I find most valuable.
How Do Expert Advisors Work for Spread Betting?
This is the primary reason most traders seek MT5 for spread betting. MQL5 allows building fully automated trading systems that execute spread bets without manual intervention. Because UK spread betting profits are tax-free (no Capital Gains Tax, no Stamp Duty), running a profitable EA on a spread bet account is one of the most tax-efficient automated trading setups available to UK retail traders. Both Pepperstone and IG support EAs on their MT5 spread bet accounts without restrictions.
What Advantage Do 21 Timeframes Give Spread Bettors?
MT5’s expanded timeframe selection is genuinely useful for multi-timeframe analysis. The 2-hour and 8-hour charts, in particular, fill gaps in MT4’s timeframe lineup that many traders have complained about for years. For a spread bettor analysing FTSE 100 or GBP/USD across multiple horizons, having 21 clean timeframes available without workarounds is a practical advantage.
How Useful Is MT5’s Depth of Market for Spread Betting?
MT5’s DOM feature shows pending order levels above and below the current price. For spread betting, this is less detailed than what a direct market access (DMA) platform provides, but it still gives more transparency than a simple bid/ask display. During the London open on Pepperstone, I found the DOM useful for gauging short-term liquidity on EUR/GBP before placing larger spread bets.
Does MT5’s Strategy Tester Speed Up Spread Betting Development?
MT5’s strategy tester runs backtests significantly faster than MT4’s by using multiple CPU cores. For spread bettors developing automated strategies, this means optimisation runs that took hours on MT4 can complete in minutes on MT5. Both Pepperstone and IG provide sufficient historical data for meaningful backtests on major spread bet markets.
Why Can’t I Use MT5 for Spread Betting With Most Brokers?
This is the question that defines this page. The UK MT5 spread betting market is extremely limited, and there are specific reasons for that.
Spread betting is UK-specific. Spread betting as a tax-free financial product exists almost exclusively in the UK and Ireland. Most international brokers build their MT5 offering around CFDs. Adding spread betting to MT5 requires UK-specific instrument configuration, FCA-compliant risk management, and GBP-per-point pricing structures that differ from standard CFD lot sizing.
MetaQuotes licensing complexity. Configuring MT5 for spread betting requires brokers to work closely with MetaQuotes to set up the platform correctly for bet-per-point instruments rather than standard contracts. Not all brokers are willing to invest in this customisation.
Specific broker situations: Capital.com offers MT5 but only through their international (non-UK) entity — the FCA-regulated UK entity does not provide MT5 access. CMC Markets offers MT5 primarily for CFD trading, not spread betting. FxPro has MT5 but not for spread betting accounts. IC Markets offers MT5 but does not provide spread betting at all.
This leaves Pepperstone and IG as the only two FCA-regulated brokers currently offering MT5 with full spread betting capability in the UK.
How Does MT5 Compare to MT4 for Spread Betting?
Both Pepperstone and IG offer MT4 as well as MT5 for spread betting. For those using MT4 specifically for spread betting, see also our best spread betting broker for MT4 guide. Here is how they compare for spread bettors specifically.
| Feature | MT5 | MT4 |
|---|---|---|
| Timeframes | 21 | 9 |
| Programming language | MQL5 (object-oriented) | MQL4 (procedural) |
| Strategy tester | Multi-threaded | Single-threaded |
| Depth of market | Yes (built-in) | Limited (plugin required) |
| Economic calendar | Built-in | Not built-in |
| Hedging mode | Yes | Yes |
| Netting mode | Yes | No |
| Order types | 6 pending order types | 4 pending order types |
| EA compatibility | MQL5 only | MQL4 only |
| Broker availability (UK SB) | 2 brokers | 3–4 brokers |
| Community size | Growing | Larger (legacy) |
My general view: for new EA development, MT5 is the better platform. For running established MT4 strategies, there is no need to switch unless the additional timeframes or faster backtesting are genuinely needed.
How Do You Set Up MT5 for Spread Betting?
Step 1: Choose a broker. The choice is between Pepperstone (FCA FRN 684312) and IG (FCA FRN 195355). Select based on whether tighter spreads/EA execution (Pepperstone) or wider market access (IG) is the priority.
Step 2: Open a spread betting account. Both brokers separate spread betting from CFD accounts. During the application process, make sure to select “Spread Betting” as the account type. On Pepperstone, choose between Standard or Razor during setup. On IG, the default account supports spread betting.
Step 3: Download and install MT5. Download from the broker’s website (not the generic MetaQuotes site). Broker-specific builds are pre-configured with the correct server settings. Available for Windows, macOS, and web on both brokers.
Step 4: Log in with spread betting credentials. Use the login credentials provided for the spread betting account specifically. If both CFD and spread betting accounts exist, they will have different login numbers.
Step 5: Verify instrument formatting. Check the Market Watch panel. Spread betting instruments should display with GBP-per-point formatting. On Pepperstone, look for “EURUSD.sb” or similar suffix. On IG, instruments are labelled with “Spread Bet” in the description.
Step 6: Configure MT5 settings. Enable hedging mode if needed (Tools > Options > Trade), set chart timeframes from all 21 options, enable one-click trading, and activate depth of market via the Market Watch panel.
Step 7: Install custom indicators or EAs (optional). Open MT5 > File > Open Data Folder > navigate to MQL5 > Experts (for EAs) or Indicators > copy the .mq5 or .ex5 files > restart MT5 or refresh the Navigator panel > drag onto a spread betting chart. If you’re new to trading platforms, see our guide to the best trading demo accounts to practise risk-free first.
Step 8: Enable automated trading. Click the “Algo Trading” button in the MT5 toolbar (it should turn green). Then ensure “Allow Algo Trading” is ticked in the EA’s properties on the specific chart.
What Are the Tax Benefits of Spread Betting via MT5?
One of the primary reasons to use MT5 for spread betting rather than MT5 for CFDs is the UK tax treatment.
Under current legislation (2025/2026 tax year), spread betting profits attract no Capital Gains Tax (HMRC treats spread bets as gambling), no Stamp Duty, and no income tax for non-professional traders. The trade-off is that losses are not tax-deductible.
Automated trading via MT5 expert advisors can generate a high volume of trades. On a CFD account, each profitable trade creates a Capital Gains Tax event. At the current CGT rate of up to 24% for higher-rate taxpayers, this erodes returns significantly over a tax year. On a spread betting account, those same automated trades generate zero CGT liability. For an EA running 5–10 trades per day over 250 trading days, the cumulative tax saving can be substantial.
Important caveat: HMRC has not published specific guidance on whether high-frequency automated spread betting could be reclassified as a trade for income tax purposes. I am not a tax adviser, and traders running intensive automated strategies on spread bet accounts may want to seek professional tax advice.
Final Thoughts
The MT5 spread betting market in the UK is small — two brokers, and that is unlikely to change dramatically in the near term. MetaQuotes’ licensing model, the UK-specific nature of spread betting, and the cost of configuring MT5 for bet-per-point instruments all contribute to this limited choice.
That said, having two strong options is better than having none. Pepperstone (FCA FRN 684312) offers the tighter spreads, superior EA execution, and unmatched platform flexibility. IG (FCA FRN 195355) counters with the widest market range of any spread betting broker and nearly five decades of institutional credibility.
For traders specifically choosing MT5 because they want to run automated strategies on a tax-efficient spread betting account, I would point most toward Pepperstone. For those who need MT5’s analytical tools across a vast range of markets and value the security of a FTSE 250-listed broker, IG is the stronger fit. See also our Pepperstone vs Trading 212 comparison if weighing Pepperstone against a commission-free alternative.
This is a specialist page for a specialist need. If MT5 is not a firm requirement, the broader best forex broker UK and best day trading platforms pages cover a much wider range of options.
FAQs
Can I use Expert Advisors (EAs) on MT5 for spread betting?
Yes. Both Pepperstone (FCA FRN 684312) and IG (FCA FRN 195355) support MQL5 expert advisors on their MT5 spread betting accounts. There are no restrictions on automated trading. I tested the same EA on both platforms during February 2026 and both executed without issues, though Pepperstone’s Razor account showed marginally faster fill times.
Is MT5 spread betting tax-free in the UK?
Spread betting profits are currently tax-free in the UK — no Capital Gains Tax and no Stamp Duty. This applies regardless of whether the trades are placed via MT5, MT4, or any other platform. The tax treatment is based on the product (spread bet) not the platform. Losses are not tax-deductible. Seek professional tax advice for individual circumstances.
Why doesn’t Capital.com offer MT5 in the UK?
Capital.com does offer MT5, but only through their international entity, which is not FCA-regulated for UK clients. The FCA-regulated UK entity of Capital.com does not currently provide MT5 access. This is a licensing and entity structure decision rather than a technical limitation.
Can I switch between MT5 and MT4 on the same spread betting account?
On Pepperstone, the same spread betting account credentials can be used to log into both MT4 and MT5 (subject to account type). On IG, separate platform access may need to be enabled. In both cases, trades opened on MT5 should be managed on MT5, and trades opened on MT4 should be managed on MT4.
Is MT5 better than MT4 for spread betting?
MT5 offers 21 timeframes (vs 9), faster multi-threaded backtesting, depth of market, a built-in economic calendar, and MQL5’s object-oriented programming. For traders building new automated strategies or requiring advanced analysis tools, MT5 is technically superior. However, MT4 has a larger legacy EA library and wider broker availability. Neither is universally “better” — it depends on the specific use case.
Why do so few brokers offer MT5 for spread betting?
Spread betting is a UK/Ireland-specific product, and most global brokers configure MT5 for CFDs. Setting up MT5 for spread betting requires custom instrument configuration (GBP-per-point pricing), FCA-specific compliance work, and close coordination with MetaQuotes. Many brokers do not find the investment justified given the relatively small UK spread betting market.
Can I access the MQL5 marketplace from a spread betting MT5 account?
Yes. The MQL5 community marketplace is accessible from within MT5 regardless of whether the account is spread betting or CFD. Indicators and EAs purchased from the marketplace work on spread betting instruments, though some may need minor adjustments to symbol naming conventions (as I found on IG during testing).
What is the minimum deposit for MT5 spread betting?
Neither Pepperstone nor IG has a formal minimum deposit. Pepperstone recommends £200 for a practical starting balance. IG has no minimum for bank transfer funding. In practice, I would suggest at least £200–500 to have adequate margin for even modest spread bet positions.
Can I use MT5 for spread betting on mobile?
Yes. Both Pepperstone and IG support the MT5 mobile app (iOS and Android) for spread betting. The mobile app retains core functionality including chart analysis, order placement, and EA monitoring (though EAs themselves must run on the desktop or VPS version).
Does MT5 spread betting support hedging?
Yes. MT5’s hedging mode is available on both Pepperstone and IG’s spread betting accounts. This allows holding simultaneous long and short positions on the same instrument. Hedging mode needs to be enabled in the account settings — MT5 defaults to netting mode on some configurations. Confirm with the broker that hedging is active on the spread betting account.
