nseries package

nseries is Algolang’s numeric series and indicator library. This reference includes its core operations, arithmetic, statistics, moving averages, technical indicators and relative-series calculations.

Use the A–Z function index to find a name, or choose a category below. Each category contains the function signatures and complete documentation from the package.

Using the package

nseries.Series is a []float64 ordered from oldest to newest. In an Algolang callback, use the indicator conversion helpers to view SDK history as a numeric series. Copy a borrowed view before retaining it beyond the callback.

For standalone numeric data in a Go package:

import "nseries"

values := nseries.New([]float64{10, 12, 14, 16, 18})
average := values.SMA(3)
latest := average.Value()   // 16
previous := average.Value(1) // 14

Algolang pins nseries in nseries.ref; make deps prepares the checkout. The module path is nseries, so a separate Go module needs a replace nseries => /path/to/checkout directive. Follow installation and dependencies for the pinned setup.

Series conventions

• The most recent value is Value() or Value(0); Value(1) reads the preceding value.
• LookBack(n) removes the latest n observations; Window(n) selects a trailing window for positive n. Check each function’s contract for empty or invalid inputs.
• Two numeric series are paired by position, not timestamps. Use SDK alignment when instruments or timeframes have different observation times.
• Warmup and missing-value behavior vary by function. Read the relevant function description before using its output as a signal.
