3 EMAs
Title: 3 EMAs in One Indicator
Description:
This indicator plots three Exponential Moving Averages (EMAs) on the same chart using a single script — ideal for TradingView plans with a limited number of indicators per chart.
Each EMA is fully customizable directly from the settings panel:
Default values are set to 9 / 21 / 50, a commonly used combination for trend and momentum analysis, but all parameters are freely adjustable to fit any trading style or timeframe.
Use case: Replace three separate EMA indicators with a single one, freeing up indicator slots on your chart.
