⚙️ Compile-Time Configuration

This module allows overriding several constants at compile time via environment variables.

Available Parameters

Variable	Default	Description
TICKER_SIZE	32	Max length of a ticker symbol
BOOK_SIZE	10	Max depth of the order book
ID_SIZE	16	Max length of ID field
MAX_WORKERS	128	Max number of concurrent workers

These values are defined in c_market_data_config.h, but can be overridden at build time.

---

🚀 Building with Custom Parameters

To override default values, set environment variables before building:

Using pip install

TICKER_SIZE=64 BOOK_SIZE=20 pip install .

Using setup.py directly

TICKER_SIZE=64 BOOK_SIZE=20 python setup.py build_ext --inplace

These environment variables are passed to the C compiler as -D flags and will override the fallback values in c_market_data_config.h.

🧪 Verify Compilation

You can verify the values were compiled correctly by running:

from algo_engine.base import C_CONFIG

print(C_CONFIG)
