Weighted Moving Average (WMA)

StratCraft indicator page for WMA.

Route: /indicators/wma/

What It Does

WMA assigns more weight to newer prices than older prices. It sits between SMA and EMA in responsiveness and is widely used in trend systems.

Formula

WMA = (n*P1 + (n-1)*P2 + ... + 1*Pn) / (n*(n+1)/2)

Parameters

  • period - default 30

C++23 API

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

Common Usage

  • Use WMA as a smoother trend line.
  • Use it for weighted crossover systems.
  • Combine it with other averages for lag reduction.

Practical Pattern

WMA is often used when you want a moving average that reacts faster than SMA without moving all the way to EMA behavior.
