How to Set 20 EMA in TradingView Easily 2026

Click Indicators in the top toolbar of any TradingView chart, then type a partial word like 'expo' into the search box rather than the full name — TradingView's search matches on substrings, so 'expo' is enough to surface every exponential-based indicator. Under the Technicals section, 'Moving Average Exponential' is the one you want; TradingView also ships a plain 'Moving Average' (simple) and several variants like Ribbon or Weighted, so it's worth reading the full name before clicking rather than grabbing the first result.

Clicking Moving Average Exponential drops it onto your chart immediately with a default length, and a small label in the top-left of the price pane confirms what's active — something like 'EMA 9 close' followed by the current value. That label is your quickest sanity check that you added the exponential version and not the simple moving average, since the two look nearly identical as a plotted line but behave differently in how they weight recent price.

Click the indicator's name where it appears on the chart, or the small gear icon next to it, to open its settings. The Length field controls the period — change it from the default to 20 and confirm. The on-chart label updates immediately to reflect the new setting, so you can verify the change without reopening the settings panel every time.

Once set, the label reads something like 'EMA 20 close' followed by the live value, and the plotted line itself hugs price more tightly than a longer-period average would, reacting faster to recent candles. This is the whole point of using a shorter EMA for short-term work: it tracks the last 20 periods with recent price weighted more heavily, so it turns and reacts closer to real time than a 50 or 200 period average ever would.

With the 20 EMA live, the most common read is simple: price consistently holding above the line suggests a short-term uptrend, and pullbacks that touch the EMA without closing decisively below it are the entries many intraday and swing traders watch for. The reverse applies in a downtrend, where the EMA acts as resistance on bounces rather than support on pullbacks.

The biggest one is trading the EMA in isolation — a single moving average tells you where price has been relative to itself, not where it's going, so pair it with price action, volume, or a second indicator for confirmation before entering. The second is applying a 20-period setting meant for short-term charts to a much higher timeframe and expecting the same pullback behavior; the same length behaves very differently on a 5-minute chart versus a weekly one.
