Overview
Trend Direction Buy/Sell Signals plots a fast EMA and a slow EMA, 20 and 50 periods by default, and colors the fast line green when it is above the slow one and red when below. BUY and SELL labels mark the crossover bars, the chart background is tinted by trend direction, and alert conditions exist for both signals. Only the two lengths can be changed.
- Fast and slow EMA lines
- BUY and SELL crossover labels
- Trend-colored fast line and background
- Alert conditions for both signals
