How to Set Up Multiple Broker Accounts in One MetaTrader 4

Updated 14 July 2026 · 7 min read · PipTax education

Setting up multiple broker accounts in one MetaTrader 4 setup is a common goal for traders who want to compare execution, test strategies across venues, or simply keep a backup account ready. It's entirely doable — you just need to understand that MT4 is built around a single broker connection per terminal, so "one MetaTrader 4" really means running several separate MT4 installs side by side on your machine.

This guide walks through the practical steps, using Pepperstone and IG as real, FCA-regulated examples of how the process looks in the real world.

Why MT4 Only Connects to One Broker Per Terminal

MetaTrader 4 isn't a universal trading app that lets you pick a broker from a dropdown. Each MT4 build is compiled and distributed by an individual broker, with that broker's price servers, symbol list and trading rules embedded in it. When you download MT4 from Pepperstone, you're getting Pepperstone's version of the platform pointing at Pepperstone's servers. IG's MT4 download works the same way for IG's servers.

This means:

• One terminal window = one broker connection at any given moment.
• You can log out and log into a different broker's server in the same terminal, but you can't have two live connections open in a single window.
• To genuinely run two brokers simultaneously, you need two separate MT4 installations.

This is by design, not a bug — it keeps each broker's pricing, execution and account data cleanly separated. Understanding this early saves confusion later when symbols look different or an EA won't behave the same way twice.

Step 1: Download Each Broker's Own MT4 Installer

Go to each broker's own platforms page and download their specific MT4 installer rather than a generic one from the MetaQuotes site, since broker-branded installers often pre-configure the correct server list.

• Visit Pepperstone's platform download page for their MT4 installer.
• Visit IG's platform page and confirm whether they currently offer MT4, MT5, or their own IG platform — availability can change, so always check directly.
• Save each installer with a clear filename so you don't mix them up.

Always confirm live platform availability, account types and costs on the broker's own website before opening an account — don't rely on older articles or forum posts, as brokers do update their platform offerings.

Step 2: Install Each Broker Into Its Own Folder

When installing, don't accept the default folder every time — each install will try to use a generic path like C:\Program Files\MetaTrader 4, which causes the second install to simply overwrite or reuse the first.

• Install broker one into a clearly named folder, e.g. MT4-Pepperstone.
• Install broker two into a separate folder, e.g. MT4-IG.
• Repeat for any additional brokers, keeping folder names unambiguous.

This keeps each terminal's data files, templates, custom indicators and Expert Advisors completely separate, so a setting or EA change in one doesn't touch the other.

Step 3: Log In With the Correct Server Name

Every MT4 account comes with a specific server name, provided in your welcome email or shown on first login. Inside the terminal, go to File > Login to Trade Account and enter:

• Your account number
• Your password
• The exact server name (e.g. something like Pepperstone-Live01 or an IG equivalent)

Getting the server name wrong is the single most common login error — it usually means you're pointing at the wrong broker or the wrong account type (demo vs live). If you can't locate it, your broker's support team can confirm it quickly.

Running Multiple Terminals Side by Side

Once both installs are logged in, you can arrange them on screen simultaneously — useful for comparing:

| What to compare | Why it matters | |---|---| | Live spread on major pairs | Real cost of entering and exiting trades | | Execution speed/slippage | Affects scalping and news-trading strategies | | Swap rates on overnight positions | Impacts holding costs for longer-term trades | | Symbol naming and minimum lot size | Can differ, affecting EA compatibility |

Don't rely on memory or screenshots for cost comparisons — use PipTax's cost tool to check current spreads and commissions systematically, since these figures change and shouldn't be assumed static from one visit to the next.

Keeping Accounts Organised and Avoiding Mistakes

Running multiple broker accounts adds real operational risk if you lose track of which terminal is which. Build simple habits from day one:

• Rename shortcuts clearly, e.g. "MT4 – Pepperstone Live" vs "MT4 – IG Demo".
• Change chart background colours per terminal as a visual cue.
• Keep a simple spreadsheet logging account numbers, servers, and purpose (demo test, live comparison, backup).
• Never assume identical lot sizing or margin requirements across brokers — check each broker's contract specifications.
• Test any Expert Advisor on demo across each broker separately before going live, since execution differences can change results.

Remember too that all FCA-regulated brokers offering retail forex trading are subject to the 30:1 leverage cap on major currency pairs — this applies broker-wide and isn't something you can bypass by opening more accounts.

Conclusion: Multiple Broker Accounts in One MetaTrader 4, Done Properly

Getting multiple broker accounts in one MetaTrader 4 setup working smoothly comes down to treating each broker as its own separate install — separate download, separate folder, separate server login — rather than trying to force one terminal to serve two masters. Once you've got Pepperstone and IG (or any other FCA-regulated brokers) running in their own clearly labelled terminals, you're in a strong position to genuinely compare execution and costs rather than guessing. Before committing real money to any comparison, run the numbers through PipTax's cost tool and check the brokers page for up-to-date details straight from each provider.

Trading carries risk, and running multiple accounts doesn't reduce that — it simply gives you better information to make cost and execution decisions with your eyes open.
