How to Read the Option Chain Popup: ATR/Distance, Buffer%, and Yield%
When you click any ticker on OptionSpeed, the option chain popup opens — a complete view of every available put and call strike for the next 4 weeks. This guide teaches you how to read every column so you can make smarter strike selection decisions.
The Option Chain Layout
The popup is organized by expiration date. Each expiration shows a table with these columns:
- Strike — The price at which the option can be exercised
- Prem — The premium (mid-price of bid/ask)
- ATR/D — Distance to strike in ATR units
- Buf% — Buffer percentage from current price
- Yield% — Annualized yield if the option expires worthless
- ⭐ — Star marker (if this strike is in Super Stocks)
The strikes above the current price are puts (red background) — these are your wheel strategy candidates. The strikes below the current price are calls (green background) — these are what you'd sell if you were already assigned and running the covered call portion of the wheel.
Understanding ATR/Distance
ATR stands for Average True Range — a measure of how much a stock typically moves in a single day. It's calculated using the stock's high, low, and close over a lookback period.
When you see ATR/D = 2.5, it means the distance from the current price to the strike equals 2.5 times the stock's average daily range. For a stock with ATR of $1.00, 2.5 ATR equals $2.50 of movement.
Why does this matter? Options pricing models (like Black-Scholes) use volatility — and ATR is a practical proxy for that. A higher ATR distance means the stock has to move more significantly, more quickly, to reach your strike. This gives you several advantages:
- Time to react — If a stock gaps down, it often bounces back within a day or two. A high ATR distance gives you time to roll or close before assignment.
- Lower assignment probability — Statistically, stocks don't frequently traverse multiple ATR units in short periods. The further your strike, the less likely assignment.
- Better premium-to-risk ratio — You're being compensated for taking on less likely but larger moves.
Rule of thumb: Look for ATR distances above 2.5 on most trades. In volatile markets (high IV), you can often get 3.0+ ATR distance even with competitive strikes. In calm markets, 2.0-2.5 may be the best available.
Buffer Percentage (Buf%)
Buffer% is simpler: it's how far the strike is below the current price, expressed as a percentage.
For example, if the stock is at $50 and the strike is $42:
- Distance = $50 - $42 = $8
- Buffer% = $8 / $50 × 100 = 16%
A 16% buffer means the stock can drop 16% before your strike gets breached. In a normal day, stocks might move 1-3%. A 16% buffer gives you room for a significant drop without assignment.
Why buffer matters more than ATR in some cases: ATR measures recent volatility, but buffer measures downside from the current price. If a stock has been trending down and is near its 52-week low, the ATR might be high (reflecting recent big moves), but the buffer might actually be tight because the stock has already fallen. Always check both.
Combining ATR and Buffer: The best strikes have both high ATR distance AND high buffer percentage. This means the stock has to move a lot in absolute and percentage terms to reach your strike. Super Stocks requires both >2.5 ATR and >15% buffer as the baseline for quality.
Yield%: Annualized Premium Return
Yield% is the annualized return you'd generate if the put expired worthless and you collected the premium. It's calculated as:
Yield% = (Premium / Strike) / DTE × 365 × 100
For example, if you sell a $40 put for $0.80 premium with 7 DTE:
- Yield = ($0.80 / $40) / 7 × 365 × 100 = 2% / 7 × 365 × 100 = 104% annualized
That sounds incredible — and it is, if the put expires worthless. But remember: yield% assumes you keep 100% of the premium. If you're assigned, the math changes because you're now holding a stock that may have dropped.
How to use yield%:
- Compare strikes on the same expiration — Higher yield typically means a further OTM strike. But is the extra premium worth the extra assignment risk?
- Compare expirations on the same strike — Longer DTE = more premium = higher yield%. But it also means more time for something to go wrong.
- Compare across stocks — A 50% yield on a volatile biotech is very different from a 50% yield on a blue-chip dividend stock. Always consider the underlying quality.
The yield trap: High yield often comes from high IV (volatile stocks). When IV is high, premium is high — but the stock is more likely to make large moves. A 100% yield sounds amazing until you get assigned and the stock drops 30%. Factor in buffer and ATR, not just yield.
The Red Line: Puts vs Calls
The red line in the option chain separates puts (strikes above current price) from calls (strikes below current price). For the wheel strategy, you're primarily interested in the put section (above the red line).
Each side has its own ATR/D and Buf% calculations:
- Puts (above red line): Distance = Price - Strike. Buffer = (Price - Strike) / Price
- Calls (below red line): Distance = Strike - Price. Buffer = (Strike - Price) / Price
Both are shown as positive numbers now, making it easy to compare risk on either side of the current price.
The ⭐ Star in the Popup
When a strike appears in Super Stocks, it gets a ⭐ marker in the option chain. This means the strike passes our quality filters (yield >30%, buffer >15%, ATR distance >2.5). Use the star as a quick quality signal — if a strike has a star, it's worth a closer look.
The stars also appear in the Super Stocks table — clicking the star there toggles it on/off. Your starred strikes are what appear in the Trade Tracking page.
Practical Example: Reading a Real Chain
Let's say AAPL is at $185 and you see the following in the option chain:
| Strike | Prem | ATR/D | Buf% | Yield% | ⭐ |
|---|---|---|---|---|---|
| $175 | $1.20 | 1.8 | 5.4% | 251% | — |
| $172 | $0.85 | 2.4 | 7.0% | 207% | — |
| $170 | $0.65 | 2.8 | 8.1% | 187% | ⭐ |
| $168 | $0.48 | 3.2 | 9.2% | 156% | ⭐ |
| $165 | $0.32 | 4.0 | 10.8% | 106% | ⭐ |
Analysis:
- $175 — High yield but only 1.8 ATR distance and 5.4% buffer. Too tight for most traders. No star.
- $172 — Borderline. 2.4 ATR is close to our 2.5 threshold. 7% buffer is thin. No star.
- $170 — Just makes Super Stocks (2.8 ATR, 8.1% buffer). The 8.1% buffer is below our 15% standard — the star is borderline here. Worth considering if you want more premium.
- $168 — 3.2 ATR and 9.2% buffer. Better distance but still below 15% buffer. The ⭐ is for making the 30% yield threshold. Fine for aggressive traders.
- $165 — 4.0 ATR is excellent. 10.8% buffer is still below our 15% standard. Very safe from assignment risk but lower buffer protection.
For a conservative wheel trader: $168 or $165 look best (high ATR distance). For an aggressive trader chasing premium: $170 might make sense despite lower buffer.
The popup gives you all the data. Your risk tolerance and account size determine which strike is right for you.
