Options explained in plain English

Qurxa is the engine inside OptionsPeek that reads scenario text, detects contract details, and helps turn plain-English option questions into editable inputs. It is pronounced KURK-sa, and the standalone Qurxa site is now live at Qurxa.com.

You will see Qurxa show up in the parser flow because that is where it earns trust: reading what you typed, what you spoke, or what a screenshot contained, then handing you something you can refine before calculating.

Delta is how much your option tends to move when the stock moves $1. A 0.50 delta call tends to gain about $0.50 if the stock rises $1. A -0.50 delta put tends to gain about $0.50 if the stock falls $1.

In OptionsPeek, Delta is the first force in the estimate. It is the quickest way to understand why an option moved a certain amount before Gamma, Theta, or Vega start bending the result.

Gamma is how fast Delta changes. High Gamma means your option's sensitivity is shifting fast while the stock moves, which is why at-the-money weeklies can suddenly feel explosive.

In OptionsPeek, Gamma is shown separately in the Greeks Breakdown so you can see when the move was not just Delta doing the work.

Theta is time decay. If you are long options, time is usually working against you. If you are short options, Theta is often the force you want on your side.

OptionsPeek treats Theta as a scenario-day effect, which helps explain why a one-day hold and a five-day hold can feel very different even if the stock move is the same.

Vega measures how much the option changes when implied volatility changes. If IV rises, long options often benefit. If IV gets crushed, buyers can be right on direction and still lose money.

That is why OptionsPeek lets you hold IV constant or model a target IV. The point is to show that stock direction is not the only driver.

Because the Greeks do not work in isolation. You might have stock movement helping you while time decay hurts you, or IV crush offsets the directional win.

This is one of the main reasons the Estimate Summary and Greeks Breakdown exist together in OptionsPeek. The summary gives the answer quickly, and the breakdown shows which forces were helping or fighting you.

OptionsPeek estimates how an option might react to a stock move under the assumptions you give it: stock price, move size, Delta, Gamma, Theta, Vega, scenario days, and implied volatility settings.

It is built for scenario questions like, "If TSLA goes up 10% tomorrow, what could this call do?" It is not trying to tell you the one true market price.

An option scenario calculator helps estimate how a specific option could react if the underlying stock or ETF moves by a chosen amount. Instead of only showing a static quote, it lets you change the stock move, time horizon, Greeks, and implied-volatility assumptions.

OptionsPeek is built around that scenario workflow. It is useful for planning and comparison, but every output should still be treated as an estimate rather than a guaranteed market price.

Yes, but the result should be treated as a planning estimate. Before the regular session opens, the stock may already be moving while the option quote is stale, wide, or unavailable.

OptionsPeek can use the premarket stock move as the scenario input, then estimate how the contract could react under the assumptions you provide. After the option chain starts trading normally, compare the estimate with the live bid/ask, spread, volume, and updated Greeks.

The stock price chart turns a single option scenario estimate into a visual range. It plots stock price on the x-axis and estimated option price on the y-axis, so you can see how the same contract may respond across nearby stock prices instead of only one target move.

That makes OptionsPeek more useful as an options scenario calculator, option price chart, and trade planning tool. You can drag or tap the chart to inspect a selected stock level, compare it with the target price, and use the curve to think through limit orders, profit and loss planning, and risk before the trade.

The Greeks Breakdown shows the estimated contribution from Delta, Gamma, Vega, and Theta so the option estimate is not just one unexplained number. Delta usually shows the first directional effect, while Gamma, Vega, and Theta explain how the result bends with stock movement, IV changes, and time decay.

Use the bar lengths to see which forces matter most in the current scenario. If Vega or Theta is doing a lot of the work, the estimate may depend heavily on volatility or time assumptions instead of stock direction alone.

The Profit / Breakeven view is a lightweight option profit calculator inside OptionsPeek. It answers a simple planning question: if you owned this call or put at an entry option price, and the stock moved to a selected target price, what would the estimated profit or loss be?

The contract line confirms the ticker, strike, side, and expiration being checked. The Contracts field controls position size, and the Entry option price is the premium per share you are assuming you paid. One standard listed option contract usually controls 100 shares, so OptionsPeek multiplies entry price by 100 and by the number of contracts.

The Target stock price control is the stock price you want to test. You can type a value or move the slider, and the breakeven marker appears on that slider when it falls inside the visible range.

Total premium paid is the estimated cost of the position: entry option price times 100 times contracts. Breakeven stock price is strike plus entry price for calls, or strike minus entry price for puts. Position value at target is the simplified intrinsic value at the target stock price, multiplied by 100 and by contracts.

The final Profit / Loss tile subtracts total premium paid from the position value at target. It shows both dollars and percent return on premium paid, and labels the outcome as Profitable, Loss, or Near breakeven when the result is close to flat.

This view is useful for quick breakeven planning, option payoff checks, and trade risk review, but it is intentionally a simplified expiration-style payoff view, not a live options pricing model. Actual option prices before expiration can differ because Greeks, implied volatility, time decay, bid/ask spread, and market conditions still matter.

Qurxa can help extract scenario details from screenshot text when those details are visible enough to recognize. It looks for fields like ticker, call or put, strike, expiration, stock price, option price, Greeks, and implied volatility.

Screenshots can be cropped, stale, blurry, or incomplete, so review the populated fields before calculating. In OptionsPeek, manual corrections remain authoritative.

Because no simple options model knows the future path of the stock, the exact volatility repricing, order flow, spreads, or event risk. A scenario estimate is useful, but it is still an estimate.

That wording is there on purpose. OptionsPeek is meant to improve thinking and reduce guesswork, not pretend uncertainty has disappeared.

It is best described as a Black-Scholes-style scenario calculator. Black-Scholes gives a useful baseline for plain-vanilla option thinking, especially when you need fallback Greeks or a fallback model price.

OptionsPeek then layers the scenario framing on top of that so you can model stock moves, IV assumptions, and time decay in a way that feels closer to the question traders are actually asking.

Because some estimates need an anchor. A percent stock move needs the current stock price. A percent option move needs the current option price or a fallback model price. IV assumptions matter when you want Vega to participate realistically.

If a required input is missing, OptionsPeek tries to tell you clearly instead of pretending the estimate is more certain than it is.

Current option price gives OptionsPeek a cleaner anchor for the before-versus-after estimate. Without it, the app may need to lean on fallback pricing assumptions to infer the starting option value.

Qurxa can sometimes detect that value from your text or screenshots, but Advanced Inputs is where you override it when you want tighter control over the estimate summary.

Hold IV constant means you are saying implied volatility does not change during the scenario. Use target IV means you want OptionsPeek to model a specific volatility level after the move, which lets Vega actively change the result.

That choice matters because a trader can be right on direction and still get surprised by volatility repricing. Qurxa helps fill the contract details, but this setting is where you decide how much IV should participate.

Days tells OptionsPeek how long the scenario has to play out. A one-day move and a five-day move can produce very different results because Theta has more time to work and Gamma exposure can evolve along the way.

If Qurxa detects an expiration but you leave Days blank, OptionsPeek defaults to 1 day. Advanced Inputs lets you stretch that horizon when the question is really about a swing trade instead of tomorrow.

Most traders think about IV in percentage points, so Vega per 1% IV means the option's sensitivity is being interpreted one volatility point at a time. That usually feels more intuitive than Vega per 1.00 IV, which is a much larger unit.

OptionsPeek keeps both choices because some data sources and traders think in different units. Advanced Inputs lets you match the math to the way your contract data was quoted.

They get shakier when the move is large, the time frame is short, or the contract is near expiration. In those situations Gamma can change quickly and volatility can reprice hard.

That is why OptionsPeek warns you on large moves. The estimate can still be useful, but it deserves more skepticism.

Yes. OptionsPeek is built around that workflow: choose the contract, set the base stock price, enter a dollar or percent stock move, then calculate an estimated option change and new option price.

The result is still an estimate, not pricing truth. Review the Greeks Breakdown, chart, IV assumptions, and Profit / Breakeven view before using the number as a planning anchor.

Yes. Curated ticker pages can start an NVDA, TSLA, SPY, AAPL, AMD, QQQ, or similar scenario, and the option contract scenario card can resolve current contract details when market data is available.

Because active names can move quickly, confirm the expiration, strike, base price, Greeks, and option price before calculating.

Start with the call contract, choose the stock move direction and amount, then calculate. Delta gives the first directional push, Gamma can add curvature, and Vega or Theta can change the result if IV or time assumptions matter.

That is why the Estimate Summary and Greeks Breakdown should be read together. The summary gives the fast estimate, and the breakdown shows what drove it.
