What It Does

ZLINDICATOR smooths price with an error-correcting style adjustment that aims to reduce lag.

Formula

The series follows an adjusted moving average that reacts faster than a plain EMA.

Parameters

• period - default 30
• gainlimit - default 50
• _movav - default EMA

C++23 API

#include <nonabt/indicators/zlindicator.hpp>
auto zlIndicator = std::make_unique<nonabt::ZLINDICATOR>(data().close(), 30, 50, "EMA");

Common Usage

• Use it as a low-lag trend baseline.
• Pair it with price crossovers or envelope logic.
• Helpful when you want lag reduction without a fully custom filter.
