BB + Volume + RSI Strategy

Here's an English explanation of your Pine Script code, designed for clarity and ease of understanding for someone familiar with trading concepts.

Pine Script Indicator: Enhanced Buy/Sell Signals (BB + Volume + RSI Combination)
This Pine Script indicator, designed for TradingView, overlays buy and sell signals directly onto your price chart. It combines three popular technical analysis tools: Bollinger Bands (BB), Volume, and the Relative Strength Index (RSI) to generate more robust trading signals.

How It Works:

This indicator calculates and displays the following:

Bollinger Bands (BB): It uses a 20-period Simple Moving Average (SMA) as the middle band, with upper and lower bands set at 2 standard deviations from the SMA. These bands help identify periods of high and low volatility, and potential overbought/oversold price levels.

RSI (Relative Strength Index): A 14-period RSI is calculated to measure the speed and change of price movements. It's primarily used here for generating sell signals when the asset is considered overbought.

Volume: A 20-period Simple Moving Average of volume is calculated to provide a baseline for typical trading activity.

Signal Generation Logic:

The indicator generates two types of buy signals and one type of sell signal:

1. Buy Signals (Green Upward Triangles)

Normal Buy Signal ("Buy" - Small Green Triangle): This signal appears when the closing price crosses above the Upper Bollinger Band. This suggests that the price is becoming overextended to the upside, often preceding a potential pullback or a strong upward trend.
Strong Buy Signal ("Strong Buy" - Large Green Triangle): This is an enhanced buy signal that appears when the closing price crosses above the Upper Bollinger Band AND the current trading volume is significantly higher than its average (specifically, 1.5 times the 20-period average volume, by default). The accompanying high volume indicates stronger conviction behind the breakout, increasing the reliability of the signal.
2. Sell Signal (Red Downward Triangle)

RSI-Based Sell Signal ("Sell" - Red Triangle): This signal appears when the RSI value crosses below 70. An RSI above 70 typically indicates an overbought condition, so a move back below 70 suggests that buying momentum is fading, potentially signaling a reversal or pullback.
Visual Representation:

Bollinger Bands: Plotted as orange lines for the upper and lower bands, and a blue line for the middle (basis) band.
Buy Signals:
"Buy" (Normal): Small green upward-pointing triangle with green text, placed below the bar.
"Strong Buy" (Volume Confirmed): Larger green upward-pointing triangle with green text, placed below the bar.
Sell Signals:
"Sell": Red downward-pointing triangle with red text, placed above the bar.
