[{"data":1,"prerenderedAt":-1},["ShallowReactive",2],{"indicator-zlemaenvelope-en":3},"# Zero Lag Exponential Moving Average Envelope (ZLEMAENVELOPE)\n\n> StratCraft indicator page for a ZLEMA-based envelope.\n\n**Route**: `\u002Findicators\u002Fzlemaenvelope\u002F`\n\n## What It Does\n\nZLEMAENVELOPE surrounds the zero-lag exponential moving average with percentage bands.\n\n## Formula\n\n`Upper = ZLEMA(period) * (1 + perc \u002F 100)` and `Lower = ZLEMA(period) * (1 - perc \u002F 100)`\n\n## Parameters\n\n- `period` - default `30`\n- `_movav` - default `EMA`\n- `perc` - default `2.5`\n\n## C++23 API\n\n```cpp\n#include \u003Cnonabt\u002Findicators\u002Fzlemaenvelope.hpp>\nauto zlemaEnvelope = std::make_unique\u003Cnonabt::ZLEMAENVELOPE>(data().close(), 30, \"EMA\", 2.5);\n```\n\n## Common Usage\n\n- Use it to detect stretched moves around a reduced-lag average.\n- Pair it with crossovers or pullback rules.\n- Helpful when you want a faster envelope than SMA or EMA bands.\n"]
