EMA 20,50,200

This indicator displays three customisable Exponential Moving Averages (EMAs) directly on your chart, helping you compare shorter, medium, and longer-term price trends.

Default settings

20-period EMA: Blue

50-period EMA: Green

200-period EMA: Red

Price source: Close

Additional smoothing: 9-period EMA applied to each EMA

Additional smoothing reduces fluctuations and produces smoother lines, while increasing lag compared with standard EMAs.

Customisation

In Settings → Inputs, you can change each EMA’s period and colour, show or hide individual lines, and select a different price source. Choose EMA, SMA, or None for smoothing, with an adjustable smoothing period. Select None to display standard EMAs without additional smoothing.

The chart title stays clean as EMA 20,50,200, with input selections hidden. The title remains fixed even when you change the periods.

Historical reference
