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")
