Summary of How the Indicator Works

The Masonson QQQ Composite Strategy (3 Indicator Alert) is a Pine Script v5 indicator designed for the QQQ (Nasdaq-100 ETF) to identify bullish and bearish trading signals based on three technical indicators: Moving Averages, MACD, and RSI. It generates buy or sell signals when at least two of three conditions align, visualizes them on the chart, and provides audible alerts and an info table for real-time monitoring.

Indicators Used:
Moving Averages: Calculates 20-period, 50-period, and 200-period Simple Moving Averages (SMAs).
MACD: Uses standard settings (12, 26, 9) to compute the MACD line and signal line.
RSI: Calculates a 7-period Relative Strength Index to identify overbought (>70) or oversold (<30) conditions.
Signal Logic:
Bullish Conditions:
Price is above 20 SMA and 20 SMA is above 50 SMA (indicating an uptrend).
MACD line is above the signal line (indicating bullish momentum).
RSI is below 30 (indicating oversold conditions).
Bearish Conditions:
Price is below 20 SMA and 20 SMA is below 50 SMA (indicating a downtrend).
MACD line is below the signal line (indicating bearish momentum).
RSI is above 70 (indicating overbought conditions).
A counter (bullishCount or bearishCount) increments for each condition met.
A signal is generated if at least 2 out of 3 conditions are met (bullishSignal or bearishSignal).
Visualization:
Plots 20 SMA (yellow), 50 SMA (orange), and 200 SMA (red) on the chart.
Displays buy signals as green upward triangles labeled "BUY" below the bar and sell signals as red downward triangles labeled "SELL" above the bar.
Implements a 5-bar cooldown to prevent signal clutter.
Shows an info table in the top-right corner with:
Bullish Count (number of bullish conditions met).
Bearish Count (number of bearish conditions met).
Current signal status (BULLISH, BEARISH, or NEUTRAL).
Alerts:
Triggers audible alerts when a new bullish or bearish signal occurs (not on consecutive bars).
Alert messages include the ticker symbol and the respective count (e.g., "Bullish Signal: QQQ - LONG entry. Count: 2").
Uses {{alert.sonify}} for audible notifications in TradingView.
Safety Features:
Includes a check to prevent simultaneous bullish and bearish signals, raising a runtime error if both occur.
