VWAP and TWAP: Execution Algorithms for Algo Traders

Institutional traders don't just slam market orders. They use sophisticated execution algorithms to minimize market impact. As your automated crypto trading size grows, you need to think the same way.

TWAP: Time-Weighted Average Price

TWAP splits an order into equal slices executed at regular time intervals. It is the simplest execution algorithm and often good enough for crypto algo trading at retail scale. Here's a minimal Python implementation:

import time\ndef twap_execute(exchange, symbol, total_qty, slices, interval_sec):\n    slice_qty = total_qty / slices\n    for _ in range(slices):\n        exchange.create_market_buy_order(symbol, slice_qty)\n        time.sleep(interval_sec)

VWAP: Volume-Weighted Average Price

VWAP weights your execution toward high-volume periods to achieve a price close to the session average. It requires historical intraday volume profiles to implement properly. VWAP is more complex but reduces high frequency crypto trading market impact significantly for larger orders.
