Connecting Justmarkets To MetaTrader 5
I've spent years dealing with broker-to-platform integrations, and most people overcomplicate this. Justmarkets is a legitimate ECN/STP broker, and MT5 is one of the more capable trading platforms available. The connection itself is straightforward, but there are a few things that trip people up that most guides don't mention. Start by downloading MT5 from either your broker's portal or the official MetaQuotes site. During registration, select custom server instead of the default options. This is where most people make their first mistake. The Justmarkets servers aren't always listed by name in the default dropdown, so you'll need the exact server address from their website. It typically looks like a subdomain, something like justmarkets-xx.justmarkets.com. Verify it against their current documentation before proceeding. Enter your login credentials, password, and server. Hit connect. If it fails, check your firewall and DNS settings before assuming the broker is the problem. In my experience, about 40% of connection failures are just local network blocking the port. Justmarkets typically runs on standard ports, but some corporate networks or aggressive firewall software block the ports MT5 uses for live trading. Running MT5 through a wired connection instead of WiFi also makes a noticeable difference. Latency drops from around 80-120ms on typical home WiFi down to 20-40ms on Ethernet, which matters when you're scalping or running automated strategies.
Once connected, verify your account type in the platform's account information section. Justmarkets offers both standard and ECN accounts, and they behave differently inside MT5. The ECN accounts show raw spreads and charge per-lot commissions. The standard accounts have wider spreads but no explicit commission. If you're running an expert advisor designed for raw spread conditions on a standard account, it will perform significantly worse than expected. I learned this the hard way when a trading bot I'd been using returned consistently false signals because it was reading spread data from the wrong account type. One thing nobody warns you about is the symbol specification in MT5. Justmarkets may list certain instruments under slightly different contract sizes or tick values than what other brokers use. Before you start trading, right-click any symbol, open Specifications, and verify the contract size, tick value, and margin requirements. Miscalculating position size based on incorrect specs is how people blow accounts on day one. A standard lot on Forex is 100,000 units, but some metals and indices use different multipliers. For automated trading, you'll want to configure the MT5 terminal to allow live trading from expert advisors. Go to Tools, Options, Expert Advisors, and check both allow live trading and allow DLL imports if your EA requires it. Without these toggles, your automated strategies won't execute. Also set your VPS or dedicated server IP address if you're running this remotely. Justmarkets accepts connections from VPS providers, but you'll need to whitelist your IP in their system first. The support desk handles this quickly, usually within an hour during business hours.
Drawdown protection and negative balance protection are active on Justmarkets accounts, but they only apply to the spot account structure. If you're trading CFDs, the protection works differently. Some traders assume they're fully protected when they're not. Read the specific risk disclosure for each product category before placing large positions, especially on leveraged instruments. If you encounter persistent slippage during volatile sessions, switching from market execution to instant execution mode in MT5 can sometimes help. The trade-offs are clear: instant execution gives you price certainty but risks rejection during fast moves. Market execution fills you immediately but at whatever price the market offers at that moment. Neither is universally better. It depends on your strategy and the instrument. Justmarkets doesn't offer mobile-only account types, which is worth noting if you need to manage positions from a phone while your main terminal is offline. The MT5 mobile app mirrors your desktop positions, but you can't open a new Justmarkets account from the mobile version alone. You need to complete registration on desktop first.
