QuantNexus indicator page for CUMSUM accumulation logic.

Route: /quantnexus/indicators/cumsum/

What It Does

CUMSUM accumulates values over time starting from an optional seed. It is a general-purpose cumulative sum helper used in quantitative logic.

Formula

CUMSUM = cumulative sum of the chosen input series + optional seed

Parameters

• seed - default 0

C++23 API

#include <nonabt/indicators/cumsum.hpp>
auto cumsum = std::make_unique<nonabt::CUMSUM>(data().close(), 0);

Common Usage

• Use CUMSUM to build running totals.
• Combine it with event logic or threshold crossing.
• Useful for cumulative return or volume aggregation workflows.

Practical Pattern

When used on returns, CUMSUM can approximate a running equity-style curve.
