45 DTE Iron Condor Results Summary - Part 2

In the last post, 45 DTE Iron Condor Results Summary, I showed the backtest results from 96,624 iron condor (IC) trades.  All of those test results were based on weekly expiration data at 45 days to expiration (DTE).  In this post, we'll look at a few key metrics and how those metrics differ between weekly data and monthly data.

The charts below are organized similar to those in the prior post. Each group of charts corresponds to the short delta listed in the heading bullet (8 delta, 12 delta, 16 delta, 20 delta).  Each column corresponds to an IC wing width (column 1 = 25 points, column 2 = 50 points, column 3 = 75 points).

The first row in each group displays the backtest results associated with weekly data, and the second row in each group displays the backtest results associated with monthly expiration data.  Weekly data could result in a new trade being initiated every week (if the entry criteria were satisfied), while the monthly expiration data would result in at most one trade per month (if the entry criteria were satisfied).  The monthly data does represent a subset of the weekly data, but will more closely match actual trade results for traders who initiate on monthly expirations rather than weekly expirations.

Lastly, trades can overlap...which means there can be multiple trades active at any point in the backtesting.  Opening a new trade does not require the prior trade to be closed.

In this post, we'll only review three metrics:

1. Normalized P&L per day
2. Normalized P&L per trade
3. Win rate

Normalized P&L per Day

• 8 delta short strikes (weekly data top, monthly data bottom)
• At 8 delta, the monthly trades show a bit better P&L per day numbers than the weekly trades.

(click to enlarge)

• 12 delta short strikes (weekly data top, monthly data bottom)
• At 12 delta, the monthly trades again show better P&L per day readings than the weekly trades.  The P&L lines are also more tightly grouped by profit taking level (50, 75, NA) as wing width increases, indicating that profit taking level has a larger impact on P&L per day than IC structure at this delta.  We noticed this same pattern with the 38 DTE ICs.

(click to enlarge)

• 16 delta short strikes (weekly data top, monthly data bottom)
• The monthly trades continue to exhibit greater P&L per day readings than the weekly trades. As wing width increases, the P&L per day lines become closer to each other and appear to converge.  The 50% profit taking level outperforms the other levels, and this trend is particularly strong in the monthly trade data.  We also continue to see stronger clustering by profit taking level, with IC structure having a smaller impact.

(click to enlarge)

• 20 delta short strikes (weekly data top, monthly data bottom)
• At 20 delta, the returns associated with the 50% profit taking level generally outperform the other profit taking levels.  We noticed this trend with the 38 DTE ICs also.

In general, the monthly trades have higher P&L per day readings than the weekly trades, but the weekly trades typically have tighter grouping of their P&L per day lines. Another trend to note is the general slope of these P&L per day lines at 45 DTE versus 38 DTE.  At 38 DTE, most of the P&L per day lines sloped down, while at 45 DTE the P&L per day lines are starting to slope up...greater P&L per day as the loss level increases.  We'll need to see if this trend continues as DTE increase.


Normalized P&L per Trade

• 8 delta short strikes (weekly data top, monthly data bottom)
• In the monthly data, we see that taking the trades to expiration resulted in larger P&L per trade results than either the 50% or 75% profit taking levels..similar to the 38 DTE trades.  The weekly data, shows a similar pattern, but the P&L per trade lines are more tightly grouped.  Lastly, the monthly P&L per trades values are slightly greater than the weekly P&L per trade values.

(click to enlarge)

• 12 delta short strikes (weekly data top, monthly data bottom)
• Not a large difference between the monthly and weekly data for the 12 delta short strikes. The monthly data has slight out-performance with no profit taking target (ST-NA) with the 50 and 75 point wing widths

(click to enlarge)

• 16 delta short strikes (weekly data top, monthly data bottom)
• Similar to the 38 DTE ICs, as the wing widths increase, we see convergence of the P&L lines by profit taking level.  As wing width increases, the IC structures have less of an impact on returns than the profit taking level.

(click to enlarge)

• 20 delta short strikes (weekly data top, monthly data bottom)
• In the weekly data, there is very little difference between the 50% and 75% profit taking levels, particularly with wing widths of 50 points and 75 points.

(click to enlarge)

There are two clear trends in the P&L per trade values:

1. As wing width increases, the difference between the P&L per trade values for the different profit taking levels and IC structures decreases...the lines become more tightly grouped.
2. In general, as loss taking levels increase, P&L per trade increases with the 45 DTE ICs.
3. The P&L per trade values are slightly greater in the monthly trades than the weekly trades...this is likely a function of more data being available for the weekly trades, which smooths out the extreme positive and negative values

Win Rate

• 8 delta short strikes (weekly data top, monthly data bottom)
• As with the 38 DTE ICs, the 50% profit taking level outperforms the other profit taking levels at 8 delta.  The win rate lines are grouped more by profit taking level than by IC structure type. The delta neutral (DN) structure out-performs the other structures at the 50% profit taking level.

(click to enlarge)

• 12 delta short strikes (weekly data top, monthly data bottom)
• At 12 delta, the 50% profit taking level continues to outperform the other profit taking levels.  Win rate differences due to structure are less significant.

(click to enlarge)

• 16 delta short strikes (weekly data top, monthly data bottom)
• At 16 delta, win rate grouping by profit taking level is even more pronounced. The monthly results are also slightly better than the weekly results.

(click to enlarge)

• 20 delta short strikes (weekly data top, monthly data bottom)
• As with the 38 DTE ICs, at 20 delta, the win rate grouping by profit taking level is even stronger.

(click to enlarge)

Similar to the 38 DTE ICs, the win rate lines have a steeper slope from the 100% loss taking level to the 200% loss taking level.  The slope tapers off after the 200% loss taking level.  Also, as short strike deltas increase, win rate decreases.

Here are a few of the "take-aways" from the 45 DTE IC backtest results...some are duplicates of the 38 DTE "take-aways":

1. Unlike the 38 DTE ICs, the P&L per trade numbers do not decrease when we move from the 100% loss taking level to the 200% loss taking level.  With the 45 DTE ICs, the P&L per trade numbers increase as we increase the loss taking %. This is more pronounced at lower deltas and larger wing widths.
2. As short strike deltas increase, the 50% profit taking level yields greater P&L per day numbers:
1. The standard IC (ST) has better P&L per day at loss taking levels of 100% and 200%
2. The delta neutral IC (DN) has better P&L per day at loss taking levels of 300% or more
3. As short strike deltas increase, take profits at lower profit taking levels.  
1. At 8 delta, the 75% profit taking level yields greater P&L per trade numbers
2. At 20 delta, the 50% profit taking level yields greater P&L per trade numbers
4. The extra long put structure (EL) generally under performs the delta neutral (DN) and standard balanced (ST) structures.
5. At the 50% profit taking level you will generally be out of your trade for a profit between 16 and 26 days.  If you haven't hit your profit target in 26 days, you should consider closing your trade.
6. The 50% profit taking level has a higher win rate than the other profit taking levels
7. The 100% loss taking level generally has a lower win rate than the larger loss taking levels.

The differences between the weekly and monthly trade data do not appear to be significant.  Going forward, unless I see a notable difference, I will not be publishing the results from the monthly trades.

45 DTE Iron Condor Results Summary

This article looks at iron condors (IC) entered at 45 days to expiration (DTE). The introduction to this series, here, describes the different variations of SPX iron condors (IC) and exits that were tested.

As mentioned in the 38 DTE IC results summary post, these tests covered 9 IC variations, with short strike deltas at four locations, utilizing 12 exits.  In all, there were 432 test runs (9 variations x 4 deltas x 12 exits). Each test run executed more than 200 SPX IC trades between the Jan-2007 expiration and the Sep-2016 expiration.  I used weekly options for this testing, so there were more than 12 trades per year.  In total, there were 96,624 total trades entered for the 45 DTE testing.

For an explanation of the nomenclature used in this article as well as the chart structure and composition, please read the first IC results post here.


Normalized P&L per Day

This first set of charts shows normalized P&L per day percentages.  The P&L per day values are expressed as a percentage of the max risk for that test run...this is necessary in order to fairly compare the returns of each of the different wing widths (25 point, 50 point, 75 point).

The results:

1. Similar to the 38 DTE ICs, there is more variability in P&L per day readings in the 25 point wing width ICs
2. Again, similar to the 38 DTE ICs, as the delta of the short strikes increases, the variability in the P&L per day readings increases
3. The largest reading was 0.18% and was associated with the three strategy variations:
1. DN (300:50), 25 point wings, 20 delta
2. DN (NA:50), 25 point wings, 20 delta
3. ST (200:50), 25 point wings, 20 delta
4. The next best reading was 0.17% and was associated with two test runs: 
1. ST (200:50), 50 point wings, 20 delta
2. ST (200:50), 75 point wings, 20 delta
5. The top 22 readings were all associated with a profit level of 50%
1. Of these 22 readings, 18 were associated with a short delta of 20

Normalized P&L per Trade

The normalized P&L per trade charts display returns expressed as a percentage of the max risk for a particular test run.

We see the following in the data:

1. The variability in normalized P&L per trade again increases as the delta of the short strike increases, and decreases with increasing wing width
2. The largest normalized P&L per trade was 5.2% for the DN (NA:50), 25 point wings, 20 delta
3. The top 7 P&L per trade variations were all associated short strike deltas of 20
4. The top 4 P&L per trade variations were all associated with profit taking at 50%
5. The top 3 trades in terms of P&L per day were also in the top three in terms of P&L per trade, but in a different order
6. The 45 DTE ICs have slightly larger P&L per trade readings than the 38 DTE ICs ( avg 2.23% / sd 0.87% VS avg 1.88% / SD 0.75%)

Win Rate

The chart structure should be familiar to you by now, so I'll not review the chart layouts.  The win rate trends are clear:

1. In general, win rates tend to increase as wing widths increase
2. Win rates tend to increase as the delta of the short strike decreases
3. The top win rate was 95%, and was associated with these strategies:
1. DN (NA:50), wing width 75, 8 delta
2. DN (NA:50), wing width 25, 8 delta
4. The top 26 strategies all had win rates of 91% or better. 
1. Of these 26, 19 took profits at 50%
2. Of these 26, 21 did not use loss exits (they exited at 2 DTE)
3. Of these 26, 20 had short strike deltas of 8
5. The strategies with the top win rates also had some of the largest single losses...as you'd expect for strategies not using loss exits
6. The win rates for the 45 DTE ICs were similar to the win rates for the 38 DTE ICs

Largest Loss

The next charts show the normalized largest loss for each of the test runs  These largest losses are expressed as a percentage of the max defined risk number for all of the 200+ trades in a test run.

The results:

1. The largest loss percentage increases with increasing short strike delta
2. The largest loss percentage increases with increasing loss taking level
3. 39 strategy variations had largest loss readings of 95% or greater
1. All 39 carried trades to 2 DTE and did not use loss taking levels
2. All wing widths, short strike deltas, and structures (ST, DN, EL) were present in these 39 strategy variations
4. The top 9 smallest losses all occurred with strategies with 75 point wing widths and 8 delta short strikes.  The top three were:
1. DN (100:50), 75 point wings, 8 delta -> 15% loss
2. DN (100:75), 75 point wings, 8 delta -> 15% loss
3. DN (100:NA), 75 point wings, 8 delta ->17% loss

Profit Factor

The best 14 profit factors were associated with delta neutral (DN) trades.  The top 10 of these 14 had 8 delta short strikes.  The top 9 of these 14 had profit factors of 2.0 or greater.

The results:

1. The top performers were:
1. DN (NA:50), 25 point wings, 8 delta -> 2.4 (win rate 95%)
2. DN (NA:50), 75 point wings, 8 delta -> 2.2 (win rate 95%)
3. DN (NA:75), 75 point wings, 8 delta -> 2.1 (win rate 93%)
4. DN (NA:NA), 75 point wings, 8 delta -> 2.1 (win rate 89%)
2. These top performers also had some of the largest single losses due to not implementing loss taking exits

Average DIT For Winning Trades

This metric was derived by averaging all of the DIT for all of the winning trades in a test run. Adding a DIT exit to your profit and loss exits is worth considering.

Here are a few trends:

1. The larger the delta of your short strikes the longer you'll need to stay in your trades
2. The larger your profit taking level, the longer you'll need to stay in your trade
3. The 50% profit taking level should have you out of your trade between 16 and 26 days for a 45 DTE IC
4. The smallest winning trade DITs of 16 were associated with 8 delta short strikes, profit taking at 50%, and loss taking at 100%...the structure type (ST, EL, DN) did not matter as seen in the charts

Part 2 will be published some time next week and will compare the weekly trades with the monthly trades.

38 DTE Iron Condor Results Summary - Part 2

In the last post, 38 DTE Iron Condor Results Summary, I showed the backtest results from 97,416 iron condor (IC) trades.  All of those test results were based on weekly expiration data at 38 days to expiration (DTE).  In this post, we'll look at a few key metrics and how those metrics differ between weekly data and monthly data.

The charts below are organized similar to those in the prior post. Each group of charts corresponds to the short delta listed in the heading bullet (8 delta, 12 delta, 16 delta, 20 delta).  Each column corresponds to an IC wing width (column 1 = 25 points, column 2 = 50 points, column 3 = 75 points).

The first row in each group displays the backtest results associated with weekly data, and the second row in each group displays the backtest results associated with monthly expiration data.  Weekly data could result in a new trade being initiated every week (if the entry criteria were satisfied), while the monthly expiration data would result in at most one trade per month (if the entry criteria were satisfied).  The monthly data does represent a subset of the weekly data, but will more closely match actual trade results for traders who initiate on monthly expirations rather than weekly expirations.

Lastly, trades can overlap...which means there can be multiple trades active at any point in the backtesting.  Opening a new trade does not require the prior trade to be closed.

In this post, we'll only review three metrics:

1. Normalized P&L per day
2. Normalized P&L per trade
3. Win rate

Normalized P&L per Day

• 8 delta short strikes (weekly data top, monthly data bottom)
• At 8 delta, the delta neutral structure outperforms the other IC structures.

(click to enlarge)

• 12 delta short strikes (weekly data top, monthly data bottom)
• At 12 delta, the 75% profit taking level results in more stable returns as wing width increases.  The P&L lines are also more tightly grouped by profit taking level (50, 75, NA) as wing width increases, indicating that profit taking level has a larger impact on P&L than IC structure at this delta.

(click to enlarge)

• 16 delta short strikes (weekly data top, monthly data bottom)
• As wing width increases, the P&L per day lines become closer to each other and appear to converge.  The 75% profit taking level outperforms the other levels, except for the delta neutral structure.  For the delta neutral IC structure, the 50% profit taking level outperforms with 25 point and 50 point wings.

(click to enlarge)

• 20 delta short strikes (weekly data top, monthly data bottom)
• At 20 delta, the returns associated with the 50% profit taking level generally outperform the other profit taking levels.

(click to enlarge)

The difference between the weekly and monthly results is not large.  In general the grouping of the P&L lines in the weekly results is "tighter" than with the monthly results.


Normalized P&L per Trade

• 8 delta short strikes (weekly data top, monthly data bottom)
• In the monthly data, we see that taking the trades to expiration resulted in larger P&L per trade results than either the 50% or 75% profit taking levels.  The weekly data, in general, shows the 75% profit taking level narrowly beating taking the trade to expiration.

(click to enlarge)

• 12 delta short strikes (weekly data top, monthly data bottom)
• Again, in the monthly data we see that taking the trades to expiration results in greater profits per trade than exiting at the 75% profit taking level.  In the weekly data, the 75% profit taking level beats taking the trades to expiration.

(click to enlarge)

• 16 delta short strikes (weekly data top, monthly data bottom)
• As the wing widths increase, we see convergence of the P&L lines by profit taking level.  The IC structure appears to have less of an impact on returns than the profit taking level...as wing width increases.

(click to enlarge)

• 20 delta short strikes (weekly data top, monthly data bottom)
• At 20 delta, the 50% profit taking level outperforms at wing widths of 25 points and 50 points.  As we increase the wing width to 75 points, the 75% profit taking level begins to outperform with increasing loss taking levels.

(click to enlarge)

The weekly results are again more tightly grouped than the monthly results.  The weekly data can result in approximately four times as many trades as the monthly data.  This increase in the number of trades in the weekly data reduces the impact of those trades with "extreme" results (both positive and negative).


Win Rate

• 8 delta short strikes (weekly data top, monthly data bottom)
• The 50% profit taking level outperforms the other profit taking levels at 8 delta.  The win rate lines appear to be grouped more by profit taking level than by IC structure type.

(click to enlarge)

• 12 delta short strikes (weekly data top, monthly data bottom)
• At 12 delta, the 50% profit taking level again outperforms the other profit taking levels.  At this delta and 50% profit taking level, the delta neutral structure outperforms the other IC structure types.

(click to enlarge)

• 16 delta short strikes (weekly data top, monthly data bottom)
• At 16 delta, win rate grouping by profit taking level is even more pronounced.

(click to enlarge)

• 20 delta short strikes (weekly data top, monthly data bottom)
• At 20 delta, the win rate grouping by profit taking level is even stronger.  The 50% profit taking level is the clear win rate winner.

(click to enlarge)

In general, the win rate lines have a steeper slope from the 100% loss taking level to the 200% loss taking level.  The slope tapers off after the 200% loss taking level.  When we review the P&L per trade numbers at the 100% loss taking level and 200% loss taking level, in general these P&L per trade numbers decrease as we move from the 100% loss taking level to the 200% loss taking level.  Even though the win rate is lower at the 100% loss taking level, the total losses are lower at this level, resulting in a greater P&L per trade value at the 100% loss taking level.

There are several "take-aways" from the results shown in these two articles:

1. As short strike deltas are increased, take profits at lower profit taking levels.  For example, at 8 delta, take profits at 75%, while at 20 delta, take profits at 50%.
2. The extra long put structure generally under performs the delta neutral and standard balanced structures.
3. At lower short strike deltas, there is value in using the delta neutral structure.  As short strike delta increases, the value in the delta neutral structure decreases.
4. At the 50% profit taking level you will generally be out of your trade for a profit between 15 and 20 days.  If you haven't hit your profit target in 20 days, you should close your trade.
5. The 50% profit taking level has a higher win rate than the other profit taking levels.
6. The 100% loss taking level generally has a higher P&L per trade than the 200% and larger loss taking levels.
7. The 100% loss taking level generally has a lower win rate than the larger loss taking levels.
