Free Trading Signals API for MT4, MT5 & Bots

Endpoints

Use From an Expert Advisor (MT4/MT5)

MQL's WebRequest function requires URLs to be whitelisted first:

1. Open MetaTrader → Tools → Options → Expert Advisors
2. Check "Allow WebRequest for listed URL"
3. Add: https://xoomar.com
4. Click OK. Restart the EA.

Sample EA Filter

#include <XoomarSignals.mqh>

void OnTick() {
   // Your normal MA crossover logic
   bool maLong = iMA(NULL,0,20,0,MODE_SMA,PRICE_CLOSE,0)
                > iMA(NULL,0,50,0,MODE_SMA,PRICE_CLOSE,0);

   // Filter: skip if Xoomar composite says strong bearish
   double composite = XoomarGetComposite("btc");
   if(maLong && composite < -0.3) {
      // Conditions say long but sentiment is deeply bearish - skip
      return;
   }

   // ... proceed with your entry logic
}

Examples

curl https://xoomar.com/api/markets/signals/btc

import requests

r = requests.get("https://xoomar.com/api/markets/signals/btc")
signal = r.json()["data"]
print(f"BTC composite: {signal['composite']}")
print(f"News: {signal['news']['score']}, Crowd: {signal['crowd']['score']}")

Honest Limits

• Data granularity is minute/hour scale. Not for HFT or sub-minute scalping.
• Signals refresh hourly (news) and every 8 hours (funding, COT weekly).
• 30 req/min per IP. Cache aggressively on your side.
• This is a sentiment filter, not a directional prediction. Use with your own strategy.

Main Features

• ✓One composite signal from -1 to +1 per asset, blending news, crowd, and institutional layers with documented weights.
• ✓Full layer transparency: every response carries the sub-scores and the raw inputs (funding percentile, COT index, article counts) that produced the composite.
• ✓Designed for machines: stable field names, numeric types, per-layer freshness timestamps, and a 60-second cache.
• ✓Free MT4/MT5 include file (XoomarSignals.mqh) for wiring signals into MetaTrader EAs.
• ✓Blend math is unit-tested and was verified by recomputing every published composite from its layers: zero mismatches.

How It Works

Signals are computed on request from the freshest layer data, cached 60 seconds.

Real Example

Response (captured live, trimmed)

{
  "data": {
    "asset": {
      "slug": "btc",
      "name": "Bitcoin",
      "kind": "crypto"
    },
    "news": {
      "score": null,
      "articleCount": 0,
      "window": "24h"
    },
    "crowd": {
      "fundingRate": 2.446e-05,
      "fundingPercentile30d": 32.22,
      "longShortRatio": null,
      "score": -0.3556
    },
    "institutional": {
      "cotNetPosition": -6558,
      "cotIndex1y": 98.08,
      "reportDate": "2026-06-02",
      "score": 0.9615
    },
    "macro": {
      "fearGreed": 12
    },
    "composite": 0.303,
    "updatedAt": {
      "news": "2026-06-12T15:00:03.798Z",
      "crowd": "2026-06-12T08:00:00.000Z",
      "institutional": "2026-06-02"
    },
    "disclaimer": "Informational only. Not financial advice."
  },
  "updatedAt": "2026-06-12T15:08:35.469Z",
  "source": "xoomar.com",
  "docs": "https://xoomar.com/markets/api"
}

A real subtlety on display: news score is null here (quiet news day for BTC), so the composite renormalizes over crowd and institutional layers only.

What People Build With This

Response Shape

Every endpoint returns the same JSON envelope: { data, updatedAt, source, docs }. The data field is an object with these fields:

The list endpoint /api/markets/signals returns this object for every covered asset. Layers are renormalized when one is missing, so composite is always comparable.

Numeric values arrive as strings where precision matters (prices, rates); parse with your language's decimal type for accounting-grade math. Rate limiting is fair-use per IP; a 429 response includes a Retry-After header. No authentication, no API key, no signup. Attribution is appreciated: xoomar.com/markets.
