Custom Fyers API Real-Time Stock Scanner

Build Custom Real-Time Stock Scanner Using Fyers API

Project Overview

I need a custom desktop or web-based stock scanner that uses real-time market data from the Fyers API to scan NSE Cash and Futures stocks based on predefined conditions.

The scanner should be lightweight, fast, reliable, and designed for intraday trading. All scan conditions and display columns must be easily customizable from the application settings without requiring code changes.

Data Source

- Fyers API (mandatory)
- Developer will be responsible for:
- Creating and configuring the Fyers App
- API integration and authentication flow
- Real-time market data fetching
- Handling API reconnects and refresh cycles

Scanner Logic

Important

A stock should appear in the results if any one of the configured conditions is satisfied.

All conditions must be user-editable and easily customizable.

---

A. Futures Scanner

Example conditions:

1. Current 1-minute Open × Current 1-minute Volume ≥ 80,000,000

2. Current 1-minute Volume ≥ 6 × Average Volume of the last 2000 one-minute candles

3. Current 1-minute Price Change (%) ≥ +0.3% or ≤ -0.3%

---

B. Cash Scanner

Example conditions:

1. Current 1-minute Open × Current 1-minute Volume ≥ 40,000,000

2. Current 1-minute Volume ≥ 10 × Average Volume of the last 2000 one-minute candles

3. Current 1-minute Price Change (%) ≥ +0.6% or ≤ -0.6%
