近年來，VPS交易逐漸在零售外匯圈内流行起來。本文將對VPS及其原理、優勢進行簡要介紹。
VPS（虛擬私人服務器）支持EA交易員進行自動交易，最大程度地縮減MT4客戶終端和MT4服務器之間的延遲。通過使用安全位置的數據中心系統，客戶可以100%地利用上線時間，體驗更快的執行速度，獲得更高的交易量，避免錯過機會。
為什麼需要VPS？
MT4 EA又稱為機器人，它可以為你進行自動化交易，但是為了保持交易的連貫，你的電腦必須時刻保持開機狀態，並且時刻連通交易服務器。
所以交易員在家中或是公司的電腦上使用EA是存在一定風險的，他們無法保證不掉線、不停電、不遇到硬件故障。
此外，如果你的電腦距離交易服務器較近，在運行EA程序時，你能享受到很低的網絡延遲和更快的報價。執行速度變快，滑點也會因此減少。
手動交易也可以使用VPS嗎？
通過遠程VPS，你可以獲得不間斷的網絡連接，但是無法享受更快的執行速度。無論你使用VPS或是家庭電腦，你都無法利用上述原理降低延遲。
VPS到底是什麼？它的原理是怎樣的？
VPS是在一個強大的機器實體服務器上建立的虛擬環境，實體服務器被分成了多個獨立的虛擬服務器。每個VPS都有獨立的帶寬、磁盤空間、内存和中央處理器資源。在VPS上運行交易軟件可以進行全天24小時的交易而不會受到上文所述的幹擾。此外，不同國家之間的網絡穩定性各有不同，這會給依賴於當地網絡的交易員帶來不利影響。在虛擬機上進行交易可以享受到穩定的環境和快速的交易流程。
因為這些虛擬環境的硬件、網絡和維護成本會分攤到很多使用者身上，所以最終每個人的使用成本會降到最低。
某些零售外匯經紀商為高級賬戶提供免費的VPS，以此提供成本效益和可衡量的解決方案，從而滿足交易者對穩定虛擬交易環境的需求。
What is Forex VPS?
Trading via a VPS has become very popular in the retail FX community over the last several years. This article aims to provide a summary of the product and its most common uses, as well as to give a general overview of the advantages of using a VPS.
A VPS (Virtual Private Server) allows traders, who use Expert Advisor (EA) automated trading systems, to minimize latency between the MT4 client terminal and the MT4 trade server. By running the system from a secure data center location, clients can also potentially receive the benefit of 100% up-time, resulting in significantly faster executions, higher trading volumes and fewer missed opportunities.
Why may a trader need a VPS?
Metatrader 4 (MT4) expert advisors, or robots, enable you to automate trading however, in order to perform consistently, your computer (with a trading terminal installed) needs to be up and running at all times with an uninterrupted connection to the trade server.
It is therefore inherently risky for a trader to run an EA on their home or work PC as there are typically no safeguards against loss of network connectivity, power interruptions or hardware failures.
Secondly, if your computer is located closer to the trade server, when running an automated strategy, you will benefit from reduced network latency and should be able to trade on the most recent quote much faster than normal. This gives the advantage of faster execution combined with reduced slippage.
Will you benefit from using VPS if you trade manually?
You will benefit from having uninterrupted access to the internet using a remote VPS but you won’t be able to take advantage of faster execution as, whether using VPS or a home PC, you will not be able to remove network latency from the equation.
What actually is a VPS? How is it created?
VPS are virtualized environments hosted on a single, powerful and robust physical server which has been divided into multiple independent virtual servers. Each VPS has its own dedicated amount of bandwidth, disk space, RAM and CPU resource. Running trading software on a VPS makes it possible for an automated system to run 24 hours a day without the concerns mentioned above. Secondly, the stability of the internet connections can vary from country to country, putting traders at a disadvantage depending on the connection possibilities available to them at their location. Trading from a virtual machine offers a stable alternative as well as a potentially faster trade route.
Because the hardware, network and maintenance costs of these virtualized environments are distributed between multiple users, the overall cost is minimized for the end consumer.
Some retail FX brokers provide free VPS for their top performing accounts as a way to offer a cost-effective and scalable solution that fulfills traders’ needs in a stable virtual trading environment.
