Only if you're hosting the bot yourself. A bot running on your home computer stops working every time that computer sleeps, updates, or loses internet — and a VPS fixes exactly that problem. If your bot runs on a cloud-hosted platform instead, the platform's servers do that job, and the VPS question simply doesn't apply to you.
What is a VPS and why do bot traders use one?
A VPS — virtual private server — is a small computer you rent inside someone else's data center, running 24 hours a day. You install your bot on it the same way you would on your laptop, then close your laptop and go to bed while the VPS keeps working. Traders use one for a single reason: a bot can only react to the market while the machine it lives on is awake and online. Home computers are terrible at staying awake and online. They restart for updates, they go to sleep, the Wi-Fi drops, someone trips over a cable. A data center machine avoids nearly all of that, which is why "get a VPS" is standard advice for anyone running their own bot software.
How much downtime does "pretty reliable" actually mean?
More than most people guess — 99% uptime still means roughly 87 hours offline per year. Here's the arithmetic: a year has 365 × 24 = 8,760 hours. If your setup is offline 1% of the time, that's 8,760 × 0.01 = 87.6 hours — about three and a half full days when your bot can't place orders, adjust positions, or react to anything. A home computer with sleep cycles, reboots, and flaky internet often does worse than 99%. A decent VPS is typically quoted at 99.9% or better, which works out to 8,760 × 0.001 = 8.76 hours a year. The gap between those two numbers is the entire case for not self-hosting on your desktop.
| Where the bot runs | Uptime (typical claim) | Offline per year (math) |
|---|---|---|
| Home computer | ~99% on a good setup | 8,760 × 0.01 ≈ 87.6 hours |
| Rented VPS | ~99.9% | 8,760 × 0.001 ≈ 8.76 hours |
| Cloud-hosted platform | Platform's responsibility | Not your problem to manage |
When do you actually need a VPS?
When you run the bot software yourself — downloaded code, a script you wrote, or any program that lives on a machine you control. In that setup, you are the hosting company: you handle uptime, restarts after crashes, software updates, and security. A VPS makes that job easier, but it doesn't make it disappear. You still have to notice when the bot process dies at 3 a.m., keep the operating system patched, and protect the API keys — the password-like credentials that let the bot trade on your exchange account — sitting on that server. A VPS costs a few dollars a month; the real cost is the ongoing system-administration work that comes with it.
