Interviewed for a software engineering role at Graham Capital and got hit with a deep question on transaction cost modeling for event-driven strategies. Pretty technical for what I expected from the process.
- In an event-driven trading strategy, how would you model and incorporate transaction costs into your system? Walk through commissions, spread, slippage, and market impact, and explain how you'd estimate these before and after execution, adjust your backtests and position sizing, and stress-test across different liquidity and latency conditions.
“This was a lot to unpack.”
