Overview

A verification pattern that confirms the TA-Lib Python wrapper is correctly installed by testing library initialization and basic function availability.

Description

After installation, verification confirms that:

1. The import talib statement succeeds
2. The C library initializes correctly (_ta_initialize() returns without error)
3. All 161 indicator functions are available (get_functions() returns full list)
4. The C library will be properly shut down at process exit (_ta_shutdown() registered via atexit)

The initialization/shutdown pair ensures proper resource management of the underlying C library.

Usage

Run a simple import and function check after every installation to verify correctness before using the library in production.

Theoretical Basis

Library lifecycle management follows the initialize/use/shutdown pattern:

# Abstract lifecycle
initialize()           # Called once on import
use_functions()        # Normal library usage
shutdown()             # Called once on process exit (via atexit)

The C library's TA_Initialize() allocates internal data structures, and TA_Shutdown() releases them. Failure to initialize results in error code 1 (TA_LIB_NOT_INITIALIZE) on any function call.
