MA Break Trend Strategy - Multi Stop Methods

This is a trend-following trading strategy with multiple stop loss options for both long and short positions.

• Entry Signal: Trades are triggered when price crosses above (long) or below (short) a configurable moving average (EMA or SMA, default 200-period)
  
• Volume Confirmation: Optional filter requiring volume to exceed a multiplier (default 1.5x) of the 20-period volume average before entering trades
  
• Five Stop Loss Methods:
  - ATR-based: Dynamic stop using Average True Range multiplier below/above entry price
  - MA Buffer: Stop set at a percentage offset from a separate moving average (default 50-period EMA)
  - Donchian Channel: Uses the lowest low/highest high over a specified lookback period
  - Keltner Channel: ATR-based bands around an EMA basis
  - Lowest Low/Highest High: Simple swing point stops based on recent price extremes
  - Trailing Stops: All stop methods automatically trail in the profitable direction (upward for longs, downward for shorts) to lock in gains while never moving against the position
