NY4, LD4, TY3, SY4 — What Broker Datacenter Codes Mean

When traders mention NY4, LD4, TY3, or SY4, they are referring to specific Equinix colocation facilities where retail forex and CFD brokers host their matching engines. Knowing which one your broker uses tells you exactly where you need to minimise latency.

TL;DR

NY4 = Equinix Secaucus NJ (US brokers and US-listed CFDs). LD4 = Equinix Slough UK (European and UK brokers, plus many globally-regulated brokers). TY3 = Equinix Tokyo (Japanese and some Asian brokers). SY4 = Equinix Sydney (Australian brokers). SG1 = Equinix Singapore (Southeast Asian brokers and some global brokers with Asian focus). TradersProxy nodes are positioned at all five.

What Equinix is and why brokers co-locate there

Equinix is the world's largest colocation datacenter operator. Co-location means brokers rent physical server space inside Equinix's facilities rather than running their own DCs. The reason: Equinix facilities are interconnected to major financial networks, dark fibre routes, and other market infrastructure. By co-locating, brokers get access to these private, ultra-low-latency network connections — and traders who connect from within the same facility (or from a proxy node there) benefit from those connections.

NY4 — The Americas hub (Secaucus, NJ)

NY4 is Equinix's flagship financial datacenter in Secaucus, New Jersey. It is directly connected to the NYSE, CME, CBOE, and major FX ECNs. Retail forex brokers with US operations (OANDA, Forex.com, Interactive Brokers) and many globally-regulated ECN brokers route US client orders through NY4. If your broker handles US equity CFDs or commodity futures, NY4 is likely part of the chain. Latency from New York City: 2–5ms. From London: 70–80ms direct, 5–10ms via TP node.

LD4 — The European hub (Slough, UK)

LD4 in Slough is the primary co-location facility for the European forex market. It hosts Currenex, FXall, EBS, and dozens of retail forex matching engines. IC Markets, Pepperstone, FP Markets, Exness, Axi, XM, Swissquote, and most FCA-regulated retail brokers use LD4. If your broker is UK/EU-regulated and offers EUR/USD, GBP/USD, or gold CFDs as primary products, their matching engine is almost certainly at LD4. Latency from London: 2–8ms. From Singapore: 150–180ms direct, 5–10ms via TP node.

TY3 — The Tokyo hub

TY3 is Equinix's main Tokyo financial facility. It hosts Japanese derivatives markets, the Tokyo Forex market, and several regional and global brokers with strong Asia-Pacific presence. Brokers with significant Japanese client bases or regional headquarters often co-locate at TY3. Latency from Tokyo: 2–5ms. From Sydney: 95–110ms direct.

SY4 — The Sydney hub

SY4 is Equinix's Sydney facility, used primarily by Australian-regulated brokers (IC Markets AU, Pepperstone AU, FP Markets). It also connects to the ASX. Latency from Sydney: 2–8ms. From Singapore: 65–80ms direct.

SG1 — The Singapore hub

SG1 is Equinix's Singapore financial datacenter, an increasingly important hub for Southeast Asian and globally-regulated brokers serving the APAC region. Many brokers now maintain servers at both SG1 and LD4. Latency from Singapore: 2–5ms. From Bangkok: 25–40ms direct.

How to find out which DC your broker uses

Method 1: Check the broker's FAQ or specification page — some list it explicitly. Method 2: Run tracert to your broker's server hostname (found in MT4 under Tools > Options > Server). The final hop's IP resolves to the Equinix facility. Method 3: Check our broker DC reference table which lists primary DCs for 14+ major brokers.

FAQ

Connect to whichever location is closest to your local time zone for the instrument you trade. For EUR/USD during London session: LD4. For US equities or Dow Jones CFDs: NY4. For APAC pairs: SY4 or TY3.

It means the broker rents server space at Equinix (or another financial DC) to be physically near the major ECNs and market infrastructure. A truly co-located broker at LD4 has order routing that stays within the Equinix network, not crossing the public internet to reach liquidity.

No. Equinix is infrastructure. It affects latency and network routing, not the broker's financial operations.

No. Many internationally-regulated brokers maintain NY4 servers to serve US dollar products (gold, US indices, USD pairs) with low latency. Regulatory jurisdiction is separate from datacenter.

SY3 and SY4 are different Equinix Sydney facilities. SY4 is the primary financial services facility. Some older documentation references SY3, but current broker co-location in Sydney is almost universally SY4.
