What Is the Finage Forex Signal API?

The Finage Forex Signal API is a real-time, AI-powered tool designed to simplify trading decisions. Instead of manually calculating technical indicators or subscribing to limited forecasting tools, this API provides automated buy, sell, or hold signals based on major forex pairs.

Built on Finage’s robust forex data infrastructure, the Signal API analyzes historical and live data to generate forecasts that are updated daily and weekly. Each signal includes:

- A recommended action (buy/sell/hold)

- A confidence score (0–100%)

- The indicator values that informed the decision (RSI, MACD, SMA, Bollinger Bands)

This approach empowers developers, fintech startups, and algorithmic traders to integrate a predictive trading layer without building forecasting logic from scratch.

 

How Does It Work? (Indicators & Confidence Score)

At its core, the Signal API leverages four essential technical indicators, often used by traders for market analysis:

RSI (Relative Strength Index): Measures momentum to detect overbought/oversold signals

MACD (Moving Average Convergence Divergence): Highlights trend shifts

SMA (Simple Moving Average): Smooths price data to spot directional moves

Bollinger Bands: Capture volatility and price extremes

The API aggregates these indicators and runs them through an AI model trained on historical forex data. The result: a suggested action with a confidence score, helping developers evaluate signal strength before executing trades.

Here’s a sample JSON response:

{

  "symbol": "EURUSD",

  "signal": "BUY",

  "confidence": 89,

  "indicators": {

    "rsi": 28.4,

    "macd": -0.0061,

    "sma": 1.0817,

    "bollinger": {

      "upper": 1.0932,

      "lower": 1.0784

    }

  },

  "timeframe": "daily"

}

 

With this, users can instantly understand not just what the recommendation is,  but why it was made.

 

Example Use Cases for the Forex Signal API

The Finage Forex Signal API is versatile and can be integrated across a range of platforms and strategies. Whether you're building a lightweight trading assistant or a full-scale fintech product, here are common scenarios where the API adds value:

Algorithmic Trading Bots

Developers can feed API signals directly into Python or Node. JS-based bots, using the buy/sell/hold recommendations to trigger or block trades. Combined with Finage’s real-time forex quotes and last trade endpoints, the Signal API becomes the decision-making core of a lightweight yet powerful bot.

Fintech Dashboards & Apps

Fintech teams can offer in-app signal cards or personalized trading suggestions to users. With confidence scoring and transparent indicator breakdowns, users stay informed and engaged.

Educational Platforms & Demo Accounts

Platforms targeting beginner traders can use the API to show how professional strategies work. Each signal can be a learning moment, enhanced by the underlying RSI, MACD, and Bollinger Band logic.

Portfolio Risk Alerts

Advanced traders or fund managers can use the API to flag directional shifts in major currency pairs. By tracking confidence scores over time, they can identify reversals or breakdowns before they happen.
