VPS placement and latency for Polymarket CLOB bots

Self-hosted prediction market automation is sensitive to where your process runs and how data reaches it. A strategy that looks fine in backtests can behave differently when your WebSocket path adds tens of milliseconds and your clock drifts. This note is about placement and plumbing, not about picking a magic instance size.

Region is a constraint, not a flex

Venues and data feeds terminate in real networks. If your bot consumes a mix of venue orderbook streams, oracle-style references, and auxiliary markets, the practical question is: where is the smallest number of hops between your process and the feeds you actually use? A VPS in a region that minimizes RTT to your dominant feed often beats a larger machine farther away.

You do not need sub-millisecond colocation for every workflow. You do need predictable latency bands so your gates and settlement windows are evaluated against data that is not silently stale.

Clock sync is part of the stack

NTP drift on a cheap VPS can show up as “the bot thought it had 20 seconds left” when the venue had 5. Before blaming the model, verify chronyc tracking or timedatectl and treat clock checks as part of deploy, not as debugging theater. The Polymarket bots guide ties this to how kits think about session windows and settlement proximity.

WebSocket and reconnect behavior

Long-lived connections drop. Your client should reconnect with backoff, resubscribe cleanly, and log gap duration. Silent partial degradation, where the book looks fine but timestamps are old, is worse than a hard disconnect because operators assume health.

What licensed kits assume

CLOB Forge kits ship as artifacts plus docs, not as a hosted control plane. You choose the host, the secrets model, and the supervision story. For SKU-specific tuning and included components, start from products. The flagship 15m scalp kit and the 5m scalp kit are common entry points once placement is sane.

Takeaway

Optimize feed path, clock, and reconnect semantics before you chase another signal. If you are still framing the problem, read the Polymarket bots guide next, then map your VPS region to the feeds your profile actually uses.
