About Short Strangle
A short strangle position consists of a short call and short put where both options have identical expirations and different strike prices. When selling a strangle short, risk is unlimited. Profit potential is limited to the net credit received (premium received for selling both strikes). The strategy succeeds if the underlying price is trading between the lower price strike (minus net credit) and the higher price strike (plus net credit).
About Long Strangle

About Short Straddle
A short straddle position consists of a short call and short put where both options have the same expiration and identical strike prices. When selling a straddle, risk is unlimited. Max Profit is limited to the net credit received (premium received for selling both strikes).

Options information is delayed a minimum of 15 minutes, and is updated at least once every 15-minutes through-out the day. The screener displays probability calculations based on the delayed stock price at the time the strategy is updated. The new day's options data will start populating the screener at approximately 8:55a CT.
Fields displayed on the Straddle and Strangle strategies include:
- Price~ - the delayed stock price at the time the strategy is updated for the underlying equity.
- Leg 1 (Call) Strike - the price at which the underlying security can be bought if the option is exercised.
- Leg 1 Bid or Ask Price - the bid or ask price of the leg 1 option
- Leg 2 (Put) Strike - the price at which the underlying security can be bought if the option is exercised.
- Leg 2 Bid or Ask Price - the bid or ask price of the leg 2 option
- +BE - the upper limit necessary for the strategy to break even (Leg1 Strike plus Net credit/debit)
- -BE - the lower limit necessary for the strategy to break even (Leg2 Strike minus Net credit/debit)
- Net Credit or Debit - the maximum profit on the spread
- % of Stock - the percentage of the premium in relation to the underlying price of the stock
- Imp Vol - The average implied volatility (IV) of the nearest monthly options contract. IV is a forward looking prediction of the likelihood of price change of the underlying asset, with a higher IV signifying that the market expects significant price movement, and a lower IV signifying the market expects the underlying asset price to remain within the current trading range. Implied volatility is calculated using the Binomial model.
- Leg 1 (Call) Delta - measures the sensitivity of the Leg 1 option's theoretical value to a change in the price of the underlying asset.
- Leg 2 (Put) Delta - measures the sensitivity of the Leg 2 option's theoretical value to a change in the price of the underlying asset.
- Break Even Probability - the probability the last price will be at or beyond the break even point at expiration.
Probability Calculation
We take the underlying stock price, the break even point (target price), the days to expiration, and the 52-week historical volatility, and then use those figures in this formula. Depending on the strategy, we use the above or below probability (i.e., the probability the price crosses the break even point).
Pabove = N(d)
Pbelow = 1 - N(d)
where
N(d)= x if d > 0
= (1-x) if d < 0
and
d = 1n(b/l) / v√t,
y = 1/(1 + 0.2316419|d|),
z = 0.3989423e - (d*d)/2,
x = 1 - z(1.330274y⁵ - 1.821256y⁴ + 1.781478y³ - 0.356538y² + 0.3193815y)
and
b = break even point
l = last price
v = 52-week historical volatility
t = days to expiration
e = 2.71828 Data Updates
