Exponential Smoothing (EXPSMOOTHING)

StratCraft indicator page for exponential smoothing.

Route: /indicators/expsmoothing/

What It Does

EXPSMOOTHING applies exponential smoothing to reduce noise while keeping recent values more important than older ones.

Formula

Smoothed = alpha * current + (1 - alpha) * previous_smoothed

Parameters

• period - default 14

C++23 API

#include <nonabt/indicators/expsmoothing.hpp>
auto exps = std::make_unique<nonabt::EXPSMOOTHING>(data().close(), 14);

Common Usage

• Use it to smooth noisy series.
• Combine it with thresholds or trend rules.
• Useful as a preprocessing step.

Practical Pattern

The smoothed line is often more stable than raw price when you need cleaner signal generation.
