Debit (Long) Put Spreads involve selling put options for an expiration of a particular underlying asset at one particular strike price and buying the same number of put options for that same expiration at a higher strike price. Because you are selling options at a lower premium than you are buying, this strategy requires a net outlay of premium at the time of the trade.

Market Price The net outlay in option premium by executing this spread trade. Because the option you're buying is a higher cost than the option you're selling, you are paying out the net difference in prices. This amount also corresponds to the maximum loss you can experience from the spread. |
Theo. Value Using a historical price return distribution for holding periods matching the # of days to expiration, we calculate a theoretical value of the current spread based on historical price changes available in this analysis. | Theo. Edge A positive edge (in green) is when the current market price of the spread is a good deal in relation to the theoretical value calculated from the historical distribution. | % Win Rate The frequency with which the current market price of the spread would have resulted in positive returns by expiration, based on the historical price changes available in this analysis. | Sharpe Ratio | Analysis | Max Gain % The maximum gain for the spread, as a percentage of the initial debit (net outlay of premium) | Spread Bid |

Breakeven Price The stock price at which the spread breaks even. If the stock is below this price, the spread will have a positive return. If it is above this price, it will lose money. |
Upside Cushion If the current stock price is below the breakeven price, this is the % change in stock price that exists as a cushion until the stock price reaches the breakeven price |
% Return if Stock Flat The % return for the option spread if the options expire with the same underlying price as the current underlying price, as a percentage of the total amount at risk |

We compile an interval-based historical price return distribution for the underlying stock
If there are 20 days to go until expiration, we go back historically and look at intervals with a 20-day holding period for changes in stock price
If there is an earnings date coming up before expiration, we look at only those historical periods that included an earnings date
Similarly, if there is no earnings date before expiration, we look at only historical periods without earnings
We use those intervals to calculate a theoretical value for the spread based on those historical changes in stock price

Example: The stock price is $100, and we have a debit put spread of Sell 105 strike and Buy 110 strike, with 25 days to go before expiration. We know that if the stock finishes below $105 (up +5%), the spread will be worth $5.00. If the stock finishes above $110 (up +10%), the spread will be worthless ($0.00 value).
Our historical return distribution could tell us, for example, that for 25-day holding periods in the past, the stock has finished +5% or below 75% of the time, and +10% or above 25% of the time.
To calculate the theoretical value then, we would add the value of the first part [75% of returns x $5.00 value = $3.75] to the value of the second part [25% of returns x $0.00 value = $0.00] to get the result, $3.75.
Using the historical distribution, we calculate a theoretical value of the current spread based on these past changes in stock price.
To determine the edge, we take that value and compare it to the current market price of the spread.
If the theoretical value is greater than the cost paid to buy the spread (Debit), then the theoretical edge will be positive. If it is lower, it will be negative.
Using the historical distribution, win rate represents the percentage of these historical observations where the current spread would have resulted in a positive return (given the observed change in stock price over the specified holding period).
This means that the end value of the spread would have been greater than the initial cost of the spread (Debit).
For the historical distribution, we've implemented a new model utilizing dynamic implied volatility ranges to narrow results around the symbol's current volatility environment. The implied volatility (IV30) is recorded at the start of each historical interval. We only select the 50% of historical observations where the IV30 at the time of the observation is the closest to the current IV30 -- 25% above and 25% below.
This way, if the current IV30 is exceptionally high or exceptionally low, we are focusing only on other historical observations that showed similar volatility.
We only utilize this method if we can ensure at least 16 observations. Otherwise, we continue to use all historical observations, as was the case prior to this method being applied.
We look at seasonal changes in stock price for up to the last 12 years (with a minimum of 8 years)
If today is May 1 and the option expires May 20, we look at the stock's price change for each year from May 1 to May 20
It finds the start and end value of the stock price for those date ranges, and calculates statistics from it
We use those values to calculate the average return and % positive observations for the stock over those results
