Options Greeks Cheat Sheet (2026) | Quick Reference — Income Trader's Guide

This Options Greeks Cheat Sheet (2026) | Quick Reference gives income traders the exact delta, gamma, theta, and vega ranges they need for covered calls, cash-secured puts, and credit spreads. Stop guessing whether your Greeks are good—use these calibrated benchmarks to enter, manage, and exit trades with confidence.

  • Delta: 0.35
  • Theta: $0.12/day
  • Gamma: 0.02
  • Vega: $0.08

Is this good? Or are you about to make a mistake?

Most traders stare at these numbers, shrug, and click "Buy" or "Sell" without really knowing if the Greeks are in their favor.

This cheat sheet removes the guesswork. It shows you exactly what "good" Greeks look like for each income strategy, and which Greeks matter most at different expiration dates. Unlike generic Greek summaries, every range below is calibrated for income traders selling premium between 7 and 45 DTE.

See real Greeks: Our Strategy Analyzer displays delta, assignment probability, and key metrics for every option—helping you quickly assess whether a trade fits your criteria.

The Greeks at a Glance

GreekWhat It MeansSeller WantsBuyer Wants
DeltaDirectional risk ($1 stock move = $X premium move)Small (0.20-0.40 for income trades)Large (0.50+ for bullish bets)
ThetaTime decay per dayLarge positive (earn money daily)Negative (lose money daily)
GammaSpeed of delta change (risk acceleration)Small (predictable risk)Large (profits accelerate)
VegaVolatility sensitivityNegative (benefit from IV drops)Positive (benefit from IV rises)

Greeks by DTE: What's "Normal"?

At 45 DTE (Entry Zone)

This is where income traders enter most positions.

For a $100 stock, $95 put (out-of-the-money):

GreekValueWhat It MeansAction
Delta-0.25 to -0.3070-75% chance expires worthless✅ Standard for income trading
Theta$0.06 to $0.10/dayEarn $0.06-0.10 daily, compounded over 45 days = $2.70-4.50✅ Good starter theta
Gamma0.015 to 0.025$1 stock move = delta changes by ~0.015-0.025 (manageable)✅ Low risk
Vega$0.06 to $0.1210% IV drop = option worth $0.60-1.20 less (helps you)✅ Positive for sellers

Decision: Good entry. Theta is steady. Gamma is manageable. Vega is on your side.


At 30 DTE (Sweet Spot)

Most profitable week for income traders. Theta accelerates, gamma is still low.

For a $100 stock, $95 put (20 days into the trade):

GreekValueWhat It MeansAction
Delta-0.27 to -0.32Slightly more sensitive (closer to expiration)⚠️ Monitor closely
Theta$0.10 to $0.15/dayEarn $0.10-0.15 daily ($3-4.50/week)✅ Theta is accelerating
Gamma0.018 to 0.028Slightly faster risk acceleration⚠️ Starting to matter
Vega$0.04 to $0.08IV sensitivity drops (less protected by time)⚠️ IV spikes hurt more now

Decision: Still good. You've captured 40-50% of max profit. Still time to hold OR close and roll to next cycle.


At 21 DTE (Decision Point)

You've captured 60-70% of max profit. Gamma is starting to accelerate.

For a $100 stock, $95 put (closing in):

GreekValueWhat It MeansAction
Delta-0.30 to -0.35More sensitive. $1 stock move = $0.30-0.35 P&L swing⚠️ Risk increasing
Theta$0.15 to $0.25/dayEarning fast ($1.05-1.75/week)✅ Peak theta acceleration
Gamma0.025 to 0.035Delta changes faster. Risk is no longer "smooth"⚠️ Major decision point
Vega$0.02 to $0.05IV changes matter a lot now❌ Very vulnerable to spikes

Decision: This is where professionals make their move. Close for ~75% profit, OR roll to the next week's option. Don't hold further unless you want binary risk.


At 14 DTE (Acceleration Zone)

Theta is amazing. Gamma is dangerous. Binary risk is real.

For a $100 stock, $95 put:

GreekValueWhat It MeansAction
Delta-0.32 to -0.40Approaching binary territory. Stock move impacts P&L heavily❌ High risk
Theta$0.20 to $0.35/dayCollect $1.40-2.45/week (amazing!)✅ Peak money maker
Gamma0.035 to 0.050$1 stock move = delta changes by 0.035-0.05 (big)❌ Risk is now asymmetric
Vega$0.01 to $0.03IV changes are huge relative to option price❌ Earnings risk

Decision: Only hold if trade is WINNING by 50%+. Theta is great but one bad earnings move wipes out 2 weeks of gains. If position is profitable, close and redeploy.


At 7 DTE (Binary Week)

Theta is your friend. Gamma is your enemy. Vega doesn't matter anymore.

For a $100 stock, $95 put:

GreekValueWhat It MeansAction
Delta-0.35 to -0.50+Deep binary. Either expires worthless or ITM❌ No middle ground
Theta$0.30 to $0.60/dayCollect $2.10-4.20 for the week (but no time for theta to save you)⚠️ Irrelevant if stock moves
Gamma0.060 to 0.100+$1 stock move = delta swings 0.060-0.10❌ Extreme risk
VegaNear $0IV changes barely matter (expiration is coming)✅ Ignore IV spikes

Decision: Close any position here unless it's clearly winning. Theta is attractive but gamma can destroy you in 24 hours. The math doesn't work in the final week.


At 3 DTE (Expiration Week)

Option is almost entirely intrinsic value. Greeks are binary.

For a $100 stock, $95 put:

GreekValueWhat It MeansAction
Delta-0.80 to -1.00Fully binary. Either expires ITM or worthless❌ No recovery
Theta$0.50+ per dayMoney is bleeding fast IF option is OTM⚠️ Works only if not assigned
Gamma0.100+Explosive. $0.50 move = 0.50 delta swing❌ Uncontrollable
VegaEssentially $0Irrelevant

Decision: Don't be here. If you closed at 21 DTE, you're already in the next cycle. If you're holding this, you're gambling, not trading.


Strategy-Specific Greek Targets

Covered Calls: What to Sell

Goal: Collect premium while capping upside on 100 shares you own.

Entry (45 DTE) - Ideal Greeks:

  • Delta: 0.30-0.40 (30-40% chance of assignment)
  • Theta: $0.06-0.12/day
  • Gamma: 0.015-0.025 (smooth P&L movement)
  • Vega: $0.06-0.12 (benefits if IV drops)

Example decision tree:

Stock up $2 since entry?
→ If Delta = 0.30: P&L loss ≈ $0.60 (manageable)
→ If Delta = 0.55: P&L loss ≈ $1.10 (keep holding if stock you want)

Theta collected $0.50 in first week?
→ Hold. You're ahead of the "theta curve"

At 21 DTE:

  • Roll if stock is high (theta is already working)
  • Close if stock dropped and delta is 0.10 (theta collected, risk = assignment)

Cash-Secured Puts: What to Sell

Goal: Collect premium while waiting to buy the stock at your strike.

Entry (45 DTE) - Ideal Greeks:

  • Delta: 0.25-0.35 (65-75% safe)
  • Theta: $0.06-0.12/day
  • Gamma: 0.018-0.028
  • Vega: $0.06-0.12

Differs from covered calls because there's no cap—you want the stock to stay ABOVE your strike, not get called away.

At 21 DTE:

  • Close if profitable and stock is nowhere near strike (theta collected, thesis played out)
  • Roll down if stock is near strike and you still want to buy

Put Credit Spreads: What to Sell

Goal: Defined risk, lower capital requirement than naked puts.

Entry (45 DTE) - Ideal Greeks:

For a $50 / $45 put spread (short 50, long 45):

PositionDeltaThetaGammaNotes
Short $50P-0.30+$0.100.020Revenue generator
Long $45P+0.15-$0.05-0.010Insurance (reduces net Greeks)
Net-0.15+$0.05/day0.010Much safer than naked put

Key advantage: Your net delta is half of a naked put's delta. Your net gamma is tiny. But theta is reduced.

When to close: When short put reaches 0.10 delta (still ~90% profit available) or at 21 DTE, whichever comes first.


Call Credit Spreads: What to Sell

Goal: Bearish position with defined risk.

Entry (45 DTE) - Ideal Greeks for a $50/$55 spread:

PositionDeltaThetaGammaNotes
Short $50C+0.30+$0.100.020Revenue: you profit if stock ≤ $50
Long $55C-0.15-$0.05-0.010Insurance: limits loss to $500
Net+0.15+$0.05/day0.010Bullish hedge on short

Similar to put spreads: Reduced delta, tiny gamma, steady theta.


Quick Decision Tree: Should I Hold This Position?

Check current Greeks vs. original Greeks

1. Delta got 2x larger than entry?
   → Stock moved against you significantly
   → Decision: Close if losing, hold if profitable

2. Theta hasn't accelerated as expected by this DTE?
   → IV might have crushed (bad for sellers after drop)
   → Decision: Close and wait for better environment

3. Gamma > 0.050 and DTE > 14?
   → You're in the gamma explosion zone too early
   → Decision: Close early to avoid risk concentration

4. Vega is tiny and DTE > 30?
   → Check IV rank. If IV rank is low, theta will be weak
   → Decision: Consider skipping this trade; wait for higher IV

5. Time to decision date (21 DTE)?
   → Check P&L: Are you at 70%+ of max profit?
   → YES: Close or roll
   → NO: Reassess fundamentals (did thesis break?)

Visual Greeks Reference

Covered Call Entry Checklist

IDEAL RANGE AT 45 DTE:

✅ Delta: [====]  0.30-0.40
✅ Theta: [====]  $0.08-0.12/day
✅ Gamma: [===]   0.015-0.025
✅ Vega:  [====]  $0.06-0.12

IF ANY OF THESE ARE OFF:
- Delta too high (>0.50)? Strike too close. Choose OTM.
- Theta too low (<$0.06)? IV is crushed. Wait for better setup.
- Gamma too high (>0.030)? Too close to expiration. Choose 45-60 DTE.
- Vega negative? Sellers don't want IV spikes. Choose higher IV environment.

At 21 DTE - Close or Roll Decision

Position check:

Status: [          50%          75%         100%      ]
        │          │            │            │
Profit: └──────────CLOSE HERE──CLOSE HERE──DON'T HOLD

Gamma: [   LOW   ===== ===== MEDIUM ===== HIGH   ]
       └──────────────────────────────────────────

Decision Matrix:
- If profit > 70% AND gamma low → HOLD one more week OR CLOSE
- If profit > 70% AND gamma HIGH → CLOSE immediately
- If profit < 70% AND stock neutral → HOLD (still collecting theta)
- If profit < 70% AND stock against you → CLOSE (de-risk)

Common Greek Mistakes (And How to Avoid Them)

Mistake 1: Ignoring Gamma at 14 DTE

Wrong: "Theta is $0.30/day! I'll hold through expiration!"

Reality: One $1 stock move = -$0.50 on your option (delta jumped 0.50)

Fix: Close by 14 DTE. Theta collection isn't worth gamma risk in final 2 weeks.


Mistake 2: Selling Too Deep ITM (High Delta)

Wrong: Sell a 0.70 delta put "because it has high probability"

Reality: Delta 0.70 = 70% CHANCE OF ASSIGNMENT (not 30%)

Fix: Sell 0.20-0.35 delta for CSPs, 0.30-0.40 delta for covered calls. The math is inverted from what new traders think.


Mistake 3: Entering When Vega is Negative (IV is Collapsing)

Wrong: "IV is 40! That's high! I'll sell now!"

Reality: IV was 60 last week. It's collapsing. Your theta will be weak tomorrow.

Fix: Check IV percentile (IV rank). Sell when IV > 50th percentile. Avoid selling into IV that's already high and dropping.


Mistake 4: Chasing Theta in the Final Week

Wrong: "This option has gamma of 0.100 but theta of $0.60/day. I'll hold!"

Reality: One overnight gap costs you 10 days of theta. And the math assumes stock stays flat, which it won't.

Fix: Exit ALL income trades by 14 DTE at the latest. Final week theta is a trap.


Greeks Ranges to Memorize

Entry (45 DTE):

  • Delta: 0.25-0.40 (income trader sweet spot)
  • Theta: $0.06-0.15/day (growing but not extreme)
  • Gamma: 0.015-0.030 (barely noticeable)

Ideal Hold (30 DTE):

  • Delta: 0.28-0.38 (still manageable)
  • Theta: $0.12-0.20/day (excellent)
  • Gamma: 0.020-0.035 (starting to matter)

Close Here (21 DTE):

  • Delta: 0.30-0.40 (decisions compound now)
  • Theta: $0.15-0.30/day (peak collection)
  • Gamma: 0.030-0.050 (risk is real)

Danger Zone (14 DTE):

  • Delta: 0.35-0.50+ (binary risk)
  • Theta: $0.25-0.50/day (not worth gamma risk)
  • Gamma: 0.050-0.100 (extreme)

The Bottom Line

Greeks tell you three things:

  1. Risk exposure (delta + gamma)
  2. Daily earnings (theta)
  3. Volatility protection (vega)

For income traders:

  • Entry at 45 DTE when delta is 0.25-0.35, theta is $0.06-0.12
  • Monitor at 30 DTE—theta is accelerating, gamma is acceptable
  • Decide at 21 DTE—close if profitable, or roll to next week
  • Avoid the final 14 days at all costs (gamma explosion, theta trap)

Print this guide, bookmark it, use it before every trade. The Greeks aren't theoretical—they're your risk dashboard.


How to Use This Cheat Sheet in Real Trades

Before you enter any position, check the Greeks against the 45 DTE entry table above. If delta is above 0.40, theta is below $0.06, or gamma is above 0.030, the setup is sub-optimal—wait for a better entry or choose a different strike.

During the trade, compare current Greeks to your entry Greeks every few days. If delta has doubled, gamma has spiked past 0.050, or theta hasn't accelerated by 30 DTE, the market environment has shifted against you. Close early rather than hope for recovery.

At 21 DTE, run the decision tree in this guide. If you're at 70%+ of max profit, close or roll. If you're below 70% and the stock has moved against you, close to preserve capital. The final two weeks are where most income traders give back profits—avoid them.
