Days Till Expiration
Some studies look at ultra-short-duration option strategies while others explore longer durations. The nuances and range for each approach are summarized below.
0 DTE Strategies
Between 0 and 3, closest to 0.
The range is up to 3 days from expiration for two reasons: to allow opening positions on Friday that have a Monday expiration and to allow more opportunities for occurrences of strategies focused in the 10-40 delta range. As expiration nears, it becomes increasingly difficult to open positions in this range.
This visual from Options Playbook does a great job illustrating the concept. Notice how at 1 DTE delta jumps from .50 to .10 with a single dollar change in the underlying. Compare this to the 60 DTE scenario where the change in delta for a $1 change in underlying is much smaller. By allowing positions to be opened as far out as 3 DTE, delta sensitivity to $1 differences in strikes becomes muted.

7 DTE Strategies
Between 3 and 11, closest to 7.
The range is 4 days either side of 7 to ensure a position can be opened each trading day while remaining true to the duration target. For example, opening a position Wednesday will have either a 2 DTE horizon (next Friday) or a 9-DTE horizon (the Friday after next). In this scenario the 9-DTE position would be selected.
45 DTE Strategies
Between 28 and 62, closest to 45.
The range is 17 days either side of 45 to account for quadruple witching. As the end of each calendar quarter approaches, namely during the last 7-10 days of Mar, Jun, Sep and Dec, the expiration dates of option contracts widen significantly.
730 DTE Strategies (LEAPS)
Between 550 and 910, closest to 730.
The range is 180 days either side of 730 to account for underlying that have LEAPS expirations in 6-month increments.
Calculating Returns
Returns are calculated daily using notional returns. The change in daily values of the option is divided by the stock price at the time of order entry.
The formula for daily return is:
option profit / opening stock price
.
For example, suppose we opened a XYZ short put at $1.10 on 1/3/2007 with a stock price of $50:
- On 1/4/2007, our option increased to $1.50. The notional daily return calculation would be ( $1.10 – $1.50 ) / $50 = -.008 which is -.8% daily return on 1/4/2007
- On 1/5/2007 our option decreased to $0.80. The notional daily return calculation would be ( $1.10 – $0.80 ) / $50 = .006 which is .6% daily return on 1/5/2007
By using notional returns on daily stock values when calculating returns we isolate the performance of the option strategy from the effects of leverage. This allows us to identify strategy performance in a non-margin context such as in a US-based retirement account.
By measuring strategy performance as a daily percentage change we abstract the strategy performance from absolute dollar gain/loss to a relative percentage value. This is a fancy way of saying the strategy becomes capital agnostic. In other words, think of an ETF that executes the respective option strategy. We can allocate $100 to the “option ETF” and $100 to the underlying and have an apples-to-apples, dollar-for-dollar comparison.
Monthly and Annual Returns
To identify the monthly and/or annual returns for an option strategy, the respective daily returns are summed.
Graphing Underlying and Option Curves
The underlying position derives its monthly performance values from Portfolio Visualizer. Portfolio returns are calculated in a compound fashion using this monthly data.
Option strategies derive monthly performance values from the backtesting tool by summing the respective daily returns. Portfolio returns are calculated using the following formula:
( backtest starting capital * monthly return ) + portfolio balance

Margin
Margin requirements and margin calls are assumed to always be satisfied and never occur, respectively.
In practice the option strategy may experience varied performance, particularly during high-volatility periods, than what’s depicted. Margin requirements may prevent the portfolio from sustaining the number of concurrent open positions the strategy demands.
Moneyness
Positions that become ITM during the life of the trade are assumed to never experience early assignment.
In practice early assignment may impact performance positively (assigned then position experiences greater losses) or negatively (assigned then position recovers).
Commission
The following commission structure is used throughout the backtest:
- 1 USD, all in, per contract:
- to open
- to close early
- expired ITM
- 0 USD, all in, per contract expired OTM / worthless
While these costs are competitive at the time of writing, trade commissions were significantly more expensive in the late 2000s and early 2010s.
In practice strategy performance may be lower than what’s depicted due to elevated trading fees in the earlier years of the backtest.
Slippage
Slippage is factored into all trade execution prices accordingly:
- Buy: Bid + (Ask – Bid) * slippage%
- Sell: Ask – (Ask – Bid) * slippage%
The following table outlines the slippage values used and example calculations:

- A slippage % of .50 = midpoint
- A slippage % of 1.00 = market maker’s price
Inflation
All values depicted are in nominal dollars. In other words, values shown are not adjusted for inflation.
In practice this may influence calculations that are anchored to a particular value in time such as the last “peak” when calculating drawdown days.
Calculating Strategy Statistics
Automated backtesters are generally great tools for generating trade logs but dismal tools to generate statistics. Therefore, I build all strategy performance statistics directly from the trade logs. Below is a breakdown on how I calculate each stat and the associated formula behind the calculation.
Win Rate
Trades that were closed at management targets (profit, DTE) as winners but became unprofitable due to commissions are considered non-winning trades. This phenomenon is typically observed when managing 2.5D and 5D trades early.
( count of trades with P/L > 0 ) / count of all trades
Annual Volatility
The standard deviation of all the monthly returns are calculated then multiplied the by the square root of 12.
STDEV.S(monthly return values) * SQRT(12)
Worst Monthly Return
Identify the smallest value among the monthly returns:
MIN(monthly return values)
Average P/L per Day
This measures changes in capital efficiency due to early management.
( average P/L per trade ) / average trade duration
Average Trade Duration
This measures the average number of days each position remains open, rounded to the nearest whole day.
ROUND ( AVERAGE ( trade duration values ) , 0 )
Compound Annual Growth Rate
This measures the compounded annual rate of return, sometimes referred to as the geometric return. The following formula is used:

Sharpe Ratio
Total P/L alone is not enough to determine whether a strategy outperforms. To get the complete picture, volatility must be taken into account. By dividing the compound annual growth rate by the volatility we identify the risk-adjusted return, known as the Sharpe ratio.
strategy CAGR / strategy volatility
Profit Spent on Commission
The following formula is used to calculate the percent of profits spent on commissions:

If a strategy is depicted as having percent greater than 100, this means the strategy is unprofitable due to commissions but would have been profitable if trades were commission free throughout the duration of the backtest.
If a strategy is depicted as “unprofitable” this means the strategy lost money even if trades were commission free throughout the duration of the backtest.
Total P/L
How much money is in the portfolio after the study? This stat answers that question and depicts it as a %
( portfolio end value / portfolio start value ) - 1
Scope
This study seeks to measure the performance of opening option positions and will interpret the results from the lens of income generation relative to buy-and-hold.
The utility or effectiveness of options as a hedging tool or other use will not be discussed and is out of scope.
Results
Win Rate


Managing trades early lowered the win rate for all strategies.
Baring the 5D early management strategy which suffered from a disproportionally large commission drag, the riskier the trade the lower the win rate.

Profit Spent on Commission


16.9% – the blended average percent of profits spent on commission across strategies.
Total P/L


Higher delta strategies yielded greater profits than lower delta strategies.
Holding till expiration yielded greater profits than managing early.
Overall

All option strategies were profitable.
Discussion
Early management hurt performance across the board. Yes, daily P/L is higher as a result of the much shorter trade durations. However, that’s more than offset by every other metric. This is a scenario where the best approach historically has been to simply place a trade then walk away.
Summary
Systematically opening cash-secured short put positions on DIS was profitable across all strategies.
Four of the 10 cash-secured DIS short put 45 DTE strategies outperformed buy-and-hold DIS on a risk-adjusted return basis. None outperformed on a total return basis.
The 10D @ hold-till-expiration strategy had the greatest risk-adjusted return among cash-secured approaches.
