Fear Greed zones and Money Waves Fused

This indicator, named "Fear Greed zones and Money Waves" combines a smoothed Money Flow Index (MFI)-based wave and the Relative Strength Index (RSI) to visualize market sentiment through fear and greed zones and generate buy/sell signals.

Core Functions
- It calculates a zero-centered and smoothed version of the MFI (MoneyWave) using configurable smoothing methods (SMA, EMA, RMA) with parameters for length and smoothing intensity.
- It uses RSI to define fear and greed zones based on user-defined thresholds (e.g., RSI below 30 indicates fear, above 70 indicates greed).
- The MoneyWave area is color-coded based on these fear/greed RSI zones: dark green for fear, dark red for greed, and yellow neutral.
- The edge line of the MoneyWave shows bullish (lime) when above zero and bearish (red) when below zero.

Visual Elements
- Plots the MoneyWave as a colored area with an edge line.
- Displays horizontal lines representing the zero line and upper/lower bounds derived from MFI thresholds.
- Optionally shows direction change arrows when the MoneyWave sign changes and labels indicating BUY or SELL signals based on MoneyWave crossing zero combined with fear/greed conditions.

Trading Signals and Alerts
- Buy signal triggers when MoneyWave crosses upward through zero while in the fear zone (RSI low).
- Sell signal triggers when MoneyWave crosses downward through zero while in the greed zone (RSI high).
- Alerts can be generated for these buy/sell events.

In summary, this indicator provides a combined measure of money flow momentum (MoneyWave) with market sentiment zones (fear and greed from RSI), helping identify potential market entry and exit points with visual markers and alerts [script].
