Six chapters of Greeks compressed into one pre-trade checklist. The Greeks you check before every options trade, in order.
Module 4 covered the four Greeks and how to read them across positions, expiry timelines, and IV regimes. If you only remember one thing: every option position has all four Greeks at once, and they ALL matter. Trading on Delta alone is the most common retail mistake.
This recap is the quick-reference: each Greek's one-liner role, the multi-leg net-Greeks reading, and the pre-trade Greeks checklist you run before every options order.
Delta: ₹ change per ₹1 underlying move. ATM ≈ ±0.50. Use for sizing directional exposure. Full chapter →
Gamma: how Delta itself shifts. Peaks at ATM and on expiry day. The option seller's hidden enemy. Full chapter →
Theta: ₹ daily decay. Accelerates to expiry. Income for sellers, cost for buyers. Full chapter →
Vega: ₹ change per 1% IV move. Highest on long-dated ATM options. Matters most around catalysts. Full chapter →
Run this before every options order. 30 seconds. Prevents most retail mistakes.
1. Net Delta: what's my directional exposure? Match to my market view.
2. Net Gamma: how does Delta change on a ±1% move? Is the worst-case Delta inside my risk tolerance?
3. Net Theta: daily decay budget. Am I OK losing this much per day if the market doesn't move? (Buyers) Am I OK with this income for the risk I'm taking? (Sellers)
4. Net Vega: IV exposure. Is there a catalyst before expiry that could move IV against me?
5. Greeks at expiry vs now: what do my Greeks look like 1 day from expiry if I hold? Often very different from today.
Module 5 (next): Options Strategies for Indian Markets — 15 strategies with payoff diagrams, live NIFTY examples, and the regime each one fits.
Module 3 (planned): Reading the Option Chain — 12 chapters on every signal a chain produces.
Delta — it's the most intuitive and the one that maps directly to 'how much do I make or lose per point move'. Once you can read Delta on every position, layer in Theta (especially for selling strategies), then Vega (for event trading), then Gamma (for expiry-day risk).
For routine trades, trust the broker terminal — Greeks are mathematically straightforward and broker math is reliable. For unusual situations (extremely high IV, weird underlying behaviour, multi-leg analysis), use Strota's strategy builder or a dedicated calculator to cross-check.
Conceptually yes — same formulas. But stock options have lower liquidity, wider spreads, and lower IV on most names. Theta and Vega are absolutely smaller. The trading edge is also smaller per lot because of those frictions.
Module 5 covers options STRATEGIES. Module 4 (this one) gave you the language. Module 5 uses that language to describe specific strategies (straddle, condor, calendar, etc.) and when each one fits. Read them in order if you can.
