Read on The5ers's own pages. Firms change rules without notice: confirm with The5ers. ProEA is an affiliate of two VPS companies, ForexVPS and FXSVPS: where a firm allows a VPS, the one link under its answer is a ForexVPS partner link, labelled as such. No firm's answer changes because of it. We're in FTMO's affiliate programme: if you open a new FTMO account through our partner link and buy, FTMO may pay us a commission. We hold a Topstep referral code, which this page doesn't show: a first-time trader who uses it gets 15% off a first Trading Combine purchase, and Topstep then gives us 15% off our own next purchase, for up to five traders every 90 days. We have no deal with any other firm named here, and the comparison is the same either way.
The5ers: VPS not stated
The5ers' pages don't mention a VPS. What they do say: you may use several devices and IP addresses from the same primary location, but must not execute trades from two IP addresses at the same time.
The5ers's own words
Each sentence is quoted from the page named under it, with the date that page carries.
“Yes, you can use multiple devices and IP addresses to access your account, provided they originate from the same primary location. However, to keep your account secure and compliant, you must not execute trades from two different IP addresses at the same time.”
“You agree that circumvention of geographical restrictions (including through the use of VPN or any other technical means) constitutes a fundamental breach of the Terms.”
“Additionally, the trader must own the source code of the EA.”
