# TradingView vs WebSocket Latency
TradingView: 500ms-3s REST. WebSocket: under 50ms streaming.
## Latency Comparison
| Source | Method | Latency | Data/min |
| TradingView free | REST | 500-3000ms | 20-120 |
| TradingView paid | REST | 200-500ms | 120-300 |
| MT5 | Bridge | 50-200ms | 300-1200 |
| GFIL Terminal | WebSocket | under 50ms | 6000+ |
## NFP Test
During NFP first minute: REST ~30 data points, WebSocket ~6000. That's 200x more data.
EURUSD can move 50+ pips in 30 seconds. With 3-second REST polling, you see 10 snapshots.
## Why Scalpers Care
5-pip target, 5-pip stop: REST latency jitter means price can move 10+ pips between updates. WebSocket eliminates this.
## Python Benchmark
import time, requests
latencies = [ ]
for i in range(100):
    t0 = time.time()
    requests.get('https://api.example.com/price')
    latencies.append((time.time() - t0) * 1000)
    time.sleep(1)
print(f"REST avg: {sum(latencies)/len(latencies):.0f}ms")
