1. Components of the Indicator
Bollinger Bands (BB):
Middle Band (midBB): A simple moving average (SMA) of the closing price over the specified length (default = 20).
Upper Band (topBB): midBB + (BB multiplier × standard deviation).
Lower Band (lowBB): midBB - (BB multiplier × standard deviation).
How to interpret Bollinger Bands:

Extreme conditions:
Price above the upper band = overbought (potential reversal or resistance).
Price below the lower band = oversold (potential reversal or support).
Moving Averages (MA):
mahi5 and mahi10: WMAs (weighted moving averages) based on the high price.
malo5 and malo10: WMAs based on the low price.
EMA 50: Exponential moving average of the closing price over 50 periods, providing an overall trend.
How to interpret moving averages:

Shorter-term MAs (mahi5 and malo5): Indicate recent price action.
Longer-term MAs (mahi10 and malo10): Indicate broader trends.
Crossovers or alignment of these moving averages with the Bollinger Bands can signal trades.

2. Trading Signals
Extreme Upper Signals:
Condition: Either mahi5 or mahi10 crosses above the upper Bollinger Band (topBB).
Visual Cue: A red downward triangle is plotted above the bar.
Interpretation: Indicates a potential overbought condition.
Action: Consider taking a short position or closing long trades, especially if the price starts reversing.
Extreme Lower Signals:
Condition: Either malo5 or malo10 crosses below the lower Bollinger Band (lowBB).
Visual Cue: A green upward triangle is plotted below the bar.
Interpretation: Indicates a potential oversold condition.
Action: Consider taking a long position or closing short trades, especially if the price starts reversing.

3. Trading Strategy
Trend Following:
Use EMA 50:
If the price is above the EMA 50, the trend is bullish. Focus on long trades, especially when extreme lower signals occur.
If the price is below the EMA 50, the trend is bearish. Focus on short trades, especially when extreme upper signals occur.
Reversal Trading:
Watch for extreme signals (mahi or malo breaching BB bands):
Extreme Upper Signal: Enter short after confirmation of a reversal (e.g., a bearish candle forms after the signal).
Extreme Lower Signal: Enter long after confirmation of a reversal (e.g., a bullish candle forms after the signal).
Confluence with Moving Averages:
If mahi or malo aligns with the Bollinger Bands, it strengthens the signal:
For Long Trades: malo5 or malo10 near or below lowBB.
For Short Trades: mahi5 or mahi10 near or above topBB.

4. Risk Management
Always set stop-loss orders based on recent price levels:
Short Trades: Above the recent swing high or topBB.
Long Trades: Below the recent swing low or lowBB.
Use risk-reward ratios (e.g., 1:2 or 1:3) to plan exits.

5. How to Read the Chart
Look for the plotted Bollinger Bands, moving averages, and signals:
Red downward triangles: Potential short trade opportunities.
Green upward triangles: Potential long trade opportunities.
Combine these signals with trend direction (EMA 50) and candle patterns for confirmation.
By following these steps, you can make informed decisions based on the BBMA strategy.
