Overview
Algo Trading: Simple 3-EMA Strategy enters long when the fast EMA crosses above the mid EMA while price is above the slow EMA, and closes that long on the opposite cross with price below the slow EMA. Short entries use the matching reverse cross and stay off by default. Size comes from a percent of equity and an assumed average-loss percent, but no stop-loss order is placed. Users change the three EMA lengths and can toggle background coloring by position.
- Three EMA overlays
- Fast-mid EMA crossover entries
- Slow EMA trend filter
- Equity percent position sizing
- Optional position background color
