FT-RSI

Summary of the Custom RSI Indicator Script (For Futu Niuniu Platform):
This Pine Script code implements a triple-period RSI indicator with horizontal reference lines (70, 50, 30) for technical analysis on the Futu Niuniu trading platform.

Key Features:

Multi-period RSI Calculation:

Computes three RSI values using 9, 14, and 22-period lengths to capture short-term, standard, and smoothed momentum signals.

Utilizes the Relative Moving Average (RMA) method for RSI calculation (ta.rma function).

Horizontal Reference Bands:

Upper Band (70): Red dotted line (semi-transparent) to identify overbought conditions.

Middle Band (50): Green dotted line as the neutral equilibrium level.

Lower Band (30): Blue dotted line (semi-transparent) to highlight oversold zones.

Visual Customization:

Distinct colors for each RSI line:

RSI (9): Orange (#F79A00)

RSI (14): Green (#49B50D)

RSI (22): Blue (#5188FF)

All lines have a thickness of 2 pixels for clear visibility.

Platform Compatibility:
This script is designed for Futu Niuniu’s charting system, leveraging Pine Script syntax adaptations supported by the platform. The horizontal bands and multi-period RSI logic help traders analyze trend strength and potential reversal points efficiently.

Note: Ensure Futu Niuniu’s scripting environment supports ta.rma and hline functions for proper execution.
