Ehlers' SuperSmoother

SuperSmoother (Ehlers SuperSmoother) is an advanced filter by John Ehlers that clears the chart of market noise with virtually no lag compared to classic moving averages (MA).

How it works

Section titled “How it works”
  1. Select SuperSmoother in the standard bot filters or configure it in the flexible indicators.
  2. When using it in standard filters specify the Interval (timeframe) and Type. Use reverse filter option, if needed.
  3. The default Period of the filter is 10.
  4. In flexible indicators, you can use the price comparison against the indicator line — Candle greater than SuperSmoother (similar to other moving averages).
  5. Also, in flexible settings, the SuperSmoother indicator itself is available with advanced parameters: Period (from 2 to 500), Interval, Method, and Shift.
  6. The algorithm filters out market noise and generates signals, reacting faster to trend changes.

SuperSmoother uses a 2-pole low-pass filter that mathematically processes prices to suppress high-frequency noise.

Limitations

Section titled “Limitations”
  • In flexible settings, the minimum period is 2 and the maximum is 500.
  • During strong flat (sideways) markets, the indicator may produce false signals.

Examples

Section titled “Examples”

Example 1: Standard Filter (Long) You set up a bot for BTC/USDT spot trading on a 15m timeframe. In standard filters, you select SuperSmoother with a period of 10. The bot waits for the price to go above the indicator line and opens a long position at the very beginning of the uptrend, avoiding the delays typical of a classic SMA.

Example 2: Flexible Indicator (Short) You launch a short bot on ETH/USDT futures on a 1h timeframe and use flexible indicators. You select the SuperSmoother indicator with a period of 20 and specify the required method and shift. The bot uses the smoothing algorithm to filter out noise and opens a short position upon a confirmed downward price reversal.

Impact on strategy

Section titled “Impact on strategy”

Using SuperSmoother provides a significant advantage in the bot’s reaction speed. By eliminating lag, the bot enters a trade at the early stages of a trend, capturing the maximum price movement.

However, the high sensitivity of the indicator requires caution in markets without a clear direction. In sideways trends, the algorithm may react to micro-breakouts, so it is better not to use it alone.

Summary

Section titled “Summary”
  • Fast Entries: A perfect replacement for moving averages (MA) to minimize delays.
  • Various Modes: Available as a standard filter, a Candle > SuperSmoother condition, and a full-fledged flexible indicator.
  • Noise Filtering: Effectively smooths the chart, cutting out random price spikes.
  • Recommendation: Use as the main trend filter in conjunction with confirming indicators.
