API Reference

TechKit provides multiple APIs for different use cases:

API Layers

Choose Your API

API	Best For	Performance	Ease of Use
Python	Data analysis, backtesting	⭐⭐⭐⭐	⭐⭐⭐⭐⭐
Node.js	Server-side, real-time	⭐⭐⭐⭐	⭐⭐⭐⭐
Browser/WASM	Web apps, charts	⭐⭐⭐	⭐⭐⭐⭐
C++	Native apps, max performance	⭐⭐⭐⭐⭐	⭐⭐⭐
C ABI	Language bindings, embedding	⭐⭐⭐⭐⭐	⭐⭐

Common Patterns

All APIs share these concepts:

Result Types

# Single value
class Result:
    value: float  # Calculated value
    valid: bool   # True if warmup complete

# Multi-output (MACD, BBands, etc.)
class MACDResult:
    macd: float
    signal: float
    histogram: float
    valid: bool

Lifecycle

Create - Instantiate with parameters
Update - Feed data incrementally, or
Calculate - Process batch data
Reset - Clear state for reuse
Destroy - Automatic (Python/C++) or explicit (C)
