Coral Trend Indicator [LazyBear] by LazyBear

This is a famous trend indicator in MT4 platform. Is this better than other MA based trend systems? I will let you decide that :)

Supported modes:
- Trend mode: This is the default. Draws a trend line (like MA) and colors them based on the trend.
- Ribbon Mode: Shown at the bottom pane. No trend lines are drawn.
- OverlayMode: Bars are colored based on the current trend. Trend line is also displayed (default color=gray).
