Practical exercises: identify the at-the-money strike for SPY today, find the 0.30 delta short put strike at 30 DTE, calculate the implied move from the ATM straddle, and identify a strike with insufficient liquidity (wide bid-ask spread). After completing the exercises, students reliably read chains 5–10× faster than before.
