Low-Latency Trading Proxy for Binance

Client

A professional Binance trader based in Belarus experiencing high latency in their trading terminal

Challenge

The trader faced severe ping and latency spikes (150–250 ms) during active trading sessions, making trading impossible. The terminal only accepts HTTP/HTTPS proxies (no SOCKS support). Direct traffic from the Russian Far East to Binance servers often routes via Moscow/Europe, adding significant latency. The optimal path — Khabarovsk → Tokyo (Pacific cables, ~25–35 ms) → Binance AWS ap-northeast-1 (~1–3 ms) — was not being used.

Solution

1. Two-Server Architecture
  • Tokyo server (closest to Binance AWS ap-northeast-1): deployed Hysteria 2 VPN server with nginx serving a decoy website, configured TLS certificates for both nginx and Hysteria 2 with additional obfuscation to prevent traffic blocking
  • Khabarovsk server (closest to client): deployed sing-box client connecting to Tokyo Hysteria 2, exposing a local SOCKS proxy, with Squid HTTP/HTTPS proxy (basic auth) as the terminal-facing endpoint
2. Protocol & Obfuscation
  • Hysteria 2 over QUIC for low-latency, loss-resilient transport
  • TLS certificates shared between nginx (decoy site) and Hysteria 2
  • Additional obfuscation layer to bypass DPI/blocking
3. Proxy Selection & Tuning
  • Tested HAProxy, 3proxy, and sing-box built-in proxy — all had either terminal authentication issues or added network latency
  • Squid with basic auth proved to be the only solution compatible with the trading terminal while maintaining low latency

Results

✅ Latency reduced from 150–250 ms to ~60 ms average terminal-to-exchange ping
✅ Trading terminal compatibility — Squid basic auth works seamlessly with the terminal’s HTTP/HTTPS proxy requirement
✅ Optimal routing — traffic flows Khabarovsk → Tokyo (Pacific cables) → Binance AWS ap-northeast-1
✅ Resilience — Hysteria 2 QUIC handles packet loss gracefully; obfuscation prevents blocking
✅ Zero terminal changes — trader continues using their existing terminal with only proxy settings updated
