Apply N (APPLYN)

StratCraft indicator page for APPLYN utility logic.

Route: /indicators/applyn/

What It Does

APPLYN applies a function to the last n values in a series. It is a general-purpose helper for custom rolling transformations.

Formula

APPLYN computes a rolling transformation using the selected function, such as sum, mean, max, min, or standard deviation.

Parameters

• period - default 14
• func - default sum

C++23 API

#include <nonabt/indicators/applyn.hpp>
auto applyn = std::make_unique<nonabt::APPLYN>(data(), 14, "sum");

Common Usage

• Use APPLYN for rolling aggregation logic.
• Combine it with custom logic pipelines.
• Useful for compacting multiple bars into one derived value.

Practical Pattern

APPLYN is a utility building block rather than a pure entry signal indicator.
