Route: /quantnexus/indicators/zlindicatorenvelope/

What It Does

ZLINDICATORENVELOPE surrounds the zero-lag indicator with upper and lower percentage bands.

Formula

Upper = ZLIndicator(period, gainlimit) * (1 + perc / 100) and Lower = ZLIndicator(period, gainlimit) * (1 - perc / 100)

Parameters

• period - default 30
• gainlimit - default 50
• _movav - default EMA
• perc - default 2.5

C++23 API

#include <nonabt/indicators/zlindicatorenvelope.hpp>
auto zlEnvelope = std::make_unique<nonabt::ZLINDICATORENVELOPE>(data().close(), 30, 50, "EMA", 2.5);

Common Usage

• Use it to spot extension around the error-correcting baseline.
• Pair it with crossovers or reversion triggers.
• Helpful when you want a lag-reduced envelope for swing systems.
