What It Does

ENVELOPE builds upper and lower percentage bands around a moving average. It is one of the simplest dynamic channel indicators.

Formula

Envelope = MA +/- perc%

Parameters

• perc - default 2.5

C++23 API

#include <nonabt/indicators/envelope.hpp>
auto envelope = std::make_unique<nonabt::ENVELOPE>(data().close(), 2.5);

Common Usage

• Use ENVELOPE for breakout and pullback logic.
• Combine it with trend filters.
• Good for coarse support/resistance mapping.

Practical Pattern

If price consistently trades above the upper envelope, the trend may be stronger than average.
