What It Does

EMA is a weighted moving average that gives more importance to recent prices. It reacts faster than an SMA and is a standard trend baseline.

Formula

EMA = [Price(t) * k] + [EMA(y) * (1 - k)], where k = 2 / (n + 1)

Parameters

  • period - default 30

C++23 API

#include <nonabt/indicators/ema.hpp>
auto ema = std::make_unique<nonabt::EMA>(data().close(), 30);

Common Usage

  • Use EMA as a trend baseline.
  • Use EMA crossovers for entries and exits.
  • Pair EMA with price confirmation or another moving average.

Practical Pattern

Buy when price closes above the EMA in an uptrend and exit when price loses the line.
