Overview
EMA_v1 marks a long triangle when price flips from below the average to above it, and a short triangle on the opposite flip. A light background shows the same bias. The only setting changes the EMA length, defaulting to 18. Alerts fire when the close is above or below the average. It does not place orders or define exits.
- Adjustable EMA length
- Green or red EMA plot
- Long and short flip markers
- Background bias shading
