Running a Real-Time Market Scanner on a VPS
A scanner is only as good as its uptime at the moments that matter — and for momentum trading those moments are 4:00–9:30 AM ET, when the day's gappers announce themselves, and the first hour of the session, when the tape is heaviest. Scanz on a home PC means booting early, hoping Windows didn't queue an update, and competing with everything else the machine does. Scanz on a VPS means the radar simply never turns off.
Why Scanning Is Heavier Than Charting
A charting platform streams the handful of symbols you're watching. Scanz streams the market: every quote and trade across US exchanges feeds its scan engine, which re-evaluates your filter criteria continuously and rebuilds watchlists as conditions change. During the open, or a broad-market news moment, that message flow spikes hard — and a machine without CPU headroom shows it as lagging scans and delayed alerts, precisely when timeliness is the product.
Our Swing plan ($45/mo, 4 Ryzen 9950X cores, 10GB DDR5) runs a focused Scanz setup — a few scan windows, montage, news — with comfortable headroom. Momentum ($85/mo, 8 cores, 20GB) is the right call for heavy multi-scan layouts, Level 2 across many symbols, or Scanz running beside your execution platform, which is how most of our momentum traders set up.
The Pre-Market Advantage of Always-On
Momentum trading's edge is often decided before most people's alarm goes off: overnight news, earnings gappers, and low-float movers surface in the pre-market scan. Because the VPS never sleeps, your Scanz session is already streaming when the 4:00 AM session opens — watchlists populated, alerts armed. Rolling out of bed and opening RDP on a phone shows a radar that has been working for hours.
The same continuity covers you during the day. Step away from the desk and alerts keep evaluating server-side; a news spike on a position hits your scanner whether or not your laptop is open. Traders tell us this is the feature they can't go back from — the scanner became infrastructure instead of an app.
Placement and the Path Your Data Travels
US equity market data originates from exchanges clustered in the New Jersey/New York data-center corridor. Placing your Scanz machine in Equinix NY7 keeps the path from those sources to your scan engine short and — more importantly for a scanner — consistent, so bursts arrive as bursts rather than smeared through a congested residential link. Your home connection then only carries compressed RDP video, which survives hotel and mobile networks fine.
This is a data-freshness argument, not an order-execution one — Scanz finds the trade; your broker platform takes it. Run both on the same VPS and the alert-to-order workflow happens entirely on one low-latency machine.
