Trading Instruction Fidelity (TIF-5)
Tests whether a model follows explicit, verifiable instructions in trading and investing contexts without access to real-time market data. Each prompt carries deterministic pass/fail constraints — exact counts, banned words, ordering, output templates, and math on provided data — so grading measures instruction compliance, not market knowledge or data access.
Prompt
Explain the difference between a market order and a limit order in exactly 3 sentences. Do not use the words 'buy' or 'sell'.
Answer guidance
PASS: Exactly 3 sentences. The words "buy" and "sell" (in any form) never appear. Content correctly distinguishes: market order executes immediately at best available price; limit order executes only at a specified price or better and may not fill. FAIL if sentence count is wrong or either banned word appears.
