How much RAM does MT5 need?
No fixed figure. FXSVPS counts 1 GB a terminal with four charts and one EA, 2 GB with about ten charts and many indicators.
What MetaQuotes and FXSVPS publish
MetaQuotes' installation help says MT5 runs on Windows 10/11 and that “hardware requirements depend on specific platform use conditions — load from running MQL5 applications, number of active instruments and charts” ( MetaQuotes, Installation). On its own hosting it allocates each platform “up to 3 GB of RAM, up to 16 GB of hard disk space” (mql5.com/en/vps). FXSVPS's MT5 page gives the rule it says it uses in tickets: “one gigabyte, one terminal” with “four charts and one expert advisor on each”, and “two gigabytes for a terminal like that” with ten charts and a stack of indicators (FXSVPS, MetaTrader 5 VPS). Its knowledge base gives 2 GB for 2–3 terminals, 4 GB for 4–6 terminals, 8 GB for 8–12 terminals (FXSVPS, Run Multiple MT4 MT5): the same company, two answers, so the calculator shows both. Your own figure is in Task Manager: terminal64.exe's memory with your charts and EAs loaded, on an ordinary trading day.
How many MT5 terminals fit on one VPS
FXSVPS prints a terminal count on every plan card. Count demo accounts and copier receivers too.
| FXSVPS plan | Memory | Cores | The card says |
|---|---|---|---|
| Eco Starter Cheap Forex VPS | 1 GB | 1 | One terminal comfortably |
| Eco Zone Cheap Forex VPS | 1.5 GB | 1 | Two terminals with light EAs |
| Eco Pro Cheap Forex VPS | 2 GB | 2 | Two terminals with EAs running |
| Lite VPS Best Forex VPS | 3 GB | 2 | Ideal for 2 to 3 terminals |
| Ultra VPS Best Forex VPS | 4 GB | 3 | Ideal for 4 to 5 terminals |
| Premium VPS Best Forex VPS | 6 GB | 4 | Ideal for 5 to 7 terminals |
| Professional VPS Best Forex VPS | 8 GB | 6 | Ideal for 7 to 8 terminals |
Where these come from, and one plan left out
From Cheap Forex VPS and Best Forex VPS, read on 29 October 2026. FXSVPS's own instruction is to “count every MT4 and MT5 window you keep open at once, including demo accounts and anything a copier feeds”, and its Cheap page says that three or more terminals should start on the Best range. Three cards name more terminals than they have gigabytes (Eco Zone two on 1.5 GB, Ultra 4 to 5 on 4 GB, Premium 5 to 7 on 6 GB), while FXSVPS's MT5 page and the Best page itself say “one gigabyte, one terminal”: the calculator keeps the gigabyte rule, so two terminals go to Eco Pro, five to Premium and seven to Professional. Its smallest plan, Starter (768 MB, “One MT4 or MT5”), has less memory than FXSVPS's own gigabyte a terminal, so the calculator doesn't pick it. Each terminal needs its own install folder: two copies can't run from one.
MetaQuotes' VPS or a Windows VPS?
MetaQuotes' hosting is one account per rented terminal, no DLLs; a Windows VPS is a whole machine you look after.
The limits that decide it
MetaQuotes' rules: “One rented terminal can work only with one User's trading account”; up to 32 charts with EAs migrate on paid hosting and 16 on free; “Any DLL calls are forbidden”, and charts without an EA don't move (MetaQuotes, VPS rules). If one account runs EAs that need no DLL, its hosting is the shortest route, rented from inside MT5. Several accounts, MT4, a DLL, or a copier between accounts on one machine point to a Windows VPS, where Windows updates and restarts are yours to manage. MT5 VPS walks renting MetaQuotes' hosting, and its prices on the day we read them.
Making MT5 use less memory
Lower Max bars in chart (minimum 5000, restart to apply) and close the charts you don't trade from.
MetaQuotes' reason
MetaQuotes' settings help: the bars shown in charts are “limited by the computer resources”, and “when multiple indicators and large amount of data to be displayed are used simultaneously, computer free resources (CPU load and free RAM) can exhaust very soon” (MetaQuotes, Platform settings). Before you pick the VPS's city, find where your broker's server answers from with the broker server location finder.
