- Created moving_average.js consolidating ma.js, ma_indicator.js, sma.js, ema.js
- Made all indicators self-contained with embedded:
* Math logic (no external dependencies)
* Metadata (getMetadata())
* Signal calculation (calculateXXXSignal)
* Base class (inline BaseIndicator)
- Updated macd.js, hts.js to inline EMA/MA calculations
- Added signal functions to RSI, BB, Stochastic, ATR indicators
- Updated indicators/index.js to export both classes and signal functions
- Simplified signals-calculator.js to orchestrate using indicator signal functions
- Removed obsolete files: ma.js, base.js, ma_indicator.js, sma.js, ema.js
All indicators now fully self-contained with no external file dependencies
for math, signal calculation, or base class.
