MT5 Retail Sentiment Index Indicator (Multi-Broker API Integration + CSV Data Logging)

Overview

Create a MetaTrader 5 (MT5) indicator that:

• Pulls live sentiment data from multiple broker APIs.

• Calculates Net Sentiment (Long% – Short%) and plots each broker as a moving average line on the chart.

• Displays a weighted average line when ≥2 feeds are active.

• Saves all data to CSV files per broker for efficient historical loading and performance.

Supported Brokers
