Tri-Indicator Trade Assist

This Pine Script indicator, named "Tri_Indicator Trade Assist", is a multi-criteria trading signal generator that combines three widely used technical analysis tools—Stochastic RSI, MACD, and RSI—along with volume and candle type confirmations. Here's a breakdown of its features and functionality:

Key Features:
1. Stochastic RSI Analysis:

Calculates %K and %D lines with user-defined smoothing and lengths.
Identifies overbought and oversold conditions based on user inputs (default levels: 80 for overbought, 20 for oversold).
Generates long and short signals using crossovers and crossunders of %K and %D, validated by oversold and overbought conditions.

2. MACD Analysis:
Calculates MACD line, signal line, and histogram using standard parameters (12, 26, 9) or user-defined inputs.
Generates long signals when the MACD line crosses above the signal line while the signal is below zero (bullish divergence).
Generates short signals when the MACD line crosses below the signal line while the signal is above zero (bearish divergence).

3. RSI Analysis:
Computes the Relative Strength Index (RSI) with a user-defined length (default: 14).
Generates long signals when RSI surpasses a customizable oversold threshold (default: 55).
Generates short signals when RSI falls below a customizable overbought threshold (default: 45).

4. Volume and Candle Confirmation:
Confirms long signals when volume exceeds its 30-period SMA, paired with a green (bullish) candle.
Confirms short signals when volume exceeds its 30-period SMA, paired with a red (bearish) candle.

5.Signal Filtration:
Avoids repetitive signals within a rolling window of five bars, ensuring reduced noise in alert generation.

6.Alerts and Visual Markers:
Generates alerts for long and short conditions with custom messages ("Go long" or "Go short").
Visually marks buy and sell signals on the chart using labeled up (green) and down (red) arrows for better clarity.

7.Customizable Parameters:
Provides flexibility through input settings for thresholds, lengths, and smoothing to suit various trading styles and asset characteristics.

Use Case:
This indicator is ideal for traders who employ a systematic approach to technical analysis. It combines momentum (RSI), trend-following (MACD), and oscillatory (Stochastic RSI) indicators with volume and price action filters, making it suitable for various trading strategies, including swing trading, scalping, and positional trading.
