This page summarises some of the trading strategies that I use in the high implied volatility environment.
The low implied volatility environment is defined as stocks or indexes with Implied Volatility (IV) Percentile or IV Rank lower than 25. I only use high volatility strategies when IV percentile is higher than 25. When it gets lower than 25, I would consider implement low volatility trading strategies as well depending on the market situation. So there is a 5 points overlap between the strategies.
NOTE on IV percentile and Rank: IV percentile and IV rank are calculated differently and IV percentile is more sensitive to the actual IV change over the defined period of time used for the calculation. I personally use Thinkorswim platform so what it gives me is what I use.
Summary of High Volatility Trade Setup
Iron Condor, Strangle
- IV percentile higher than 25% for Indexes and 50% for stocks.
- If I need to make a trade between IV percentile 25-50%, I will try to go out more in time (example: choose 60 days expiration instead of 45 days) as it has been shown longer time can compensate the low IV somewhat, but not by much.
- Exit at 35% – 50% max profit. If too close to the expiration 35%, if not than 50%.
- IV percentile must be higher than 80%.
- Never place this trade on a short time duration, unless there is a binary event (earning) so that I know the IV percentile will drop immediately after the event.
- Exit at 25% max profit. This should be achieved after about 25 days with 45 days expiration options. If it takes longer than that, consider getting out.
Iron Condor is essentially a combination of far out of the money Call Credit Spread and Put Credit Spread.
Typically, they are one standard deviation out of the money (68%). In other words about 0.15 Delta for each side so combined probability of losing would be about 30%. The idea is to set up the Credit spreads far out enough on each side so they would expire worthless with a high probability of success.
This might sound like a “dream comes true” setup, but in reality it has several drawbacks as discussed below.
Also, instead of letting it expire, taking the money off the table after hitting certain target (for example, 35% of the maximum profit) would be an ideal move in many cases.
1) It needs to have enough open option interests
Not every underlying securities have large open option interests out the money so this would limit the number of candidates. Indexes such as SPY, SPX, QQQ are good candidates. 2
2) Implied volatility of the underlying security ideally should be high (higher the better)
Since we are selling options to get credit, we want to take advantage of high implied volatility because it would make options more expensive. As the volatility drops, it would help is getting closer to the target price.
Chicken Iron Condor
One of the most confusing aspect in options trading I found is the name used for strategies. In some cases, different names are used for essentially the same strategy. Chicken Iron Condor is one of those strategies.
Essentially, by moving the Call and Put options sold closer to the underlying security’s current price, it creates a narrower and taller return curve.
Iron Butterfly (a.k.a. Ironfly or Synthetic Straddle)
This strategy is a good alternative to selling Straddle if your trading account (also an IRA account) is not permitted to sell unlimited risk options. Some people refer this to a Synthetic Straddle because of the risk / return earning curve it creates is exactly the same as Straddle yet with limited risk.
I personally use this in IRA accounts and for Straddle trades that would require way too much margin.
Here is the link to Wikipedia about Iron Butterfly.
Is Iron Butterfly as good as Straddle?
Studies done by Tastytrade shows that Straddle is a better choice than Iron Butterfly in the high IV environment.
On the other hand, in the lower IV environment, Iron Butterfly is a better choice. However, it is important to note that both Iron Butterfly and selling straddle shouldn’t be the strategies to choose in a low IV environment to start with. In low IV environment, use these strategies instead.
So the message here is that, if selling Straddle is an option, choose that instead of Iron Butterfly.
Sell Naked Straddle
This strategy is only limited to accounts that can execute unlimited risk options trading such as selling naked Call. You would need to apply for an approval from your brokerage firm.
Instead of buying an out of the money Call and Put options to create a limited risk trade, this strategy would only sell Call and PUT to create a pyramid like risk to return graph. As you can see from the image below, it could look pretty scary because of the unlimited downside risk.
However, by eliminating the need to buy out of the money Call and Put, it not only making the trade gets executed more easily and save some transaction cost, it also widens the break even points a little wider and reaching to the target exit point little easier.
I personally only use this when there is a very high IV Percentile. Ideally above 80%.
When to sell Straddles?
Based on the studies done by folks at Tasteytrade.com, this strategy should be carried out ONLY when Implied Volatility is at least higher than 50%. In fact, if you watch this video, it explains that out of the money strangle should be used instead of in the money strangle when there is a low volatility.
NOTE: Study period Jan 2009 – Aug 2014
How to manage Straddles
A screenshot from this Tastydtrade video shows the expected Straddle trade return based on the days held.
This table could give you a baseline to compare with in case you wonder if you should get out of a trade after certain days.
For example, after 10 days of entering a Straddle trade, you are seeing 20% profit. This is a much better return than what’s shown in the table so if you want to get out of the trade, you should.
Sell Naked Strangle
This is essentially the unlimited risk version of Iron Condor.
Why these strategies should not be implemented in low IV environment
A study done by Tastytrade shows that simply the strategies mentioned on this page are better in the high IV environment.
Straddle vs Strangle
This Tastytrade study shows the difference between Straddle and Strangle in terms of expected return based on days held.

VIX options trading
VIX is constructed using the implied volatilities of a wide range of S&P 500 index options. It is also known as the “fear gauge” of the market because it shows the market’s expectation of 30-day volatility.
The tricky part of trading VIX option is because its underlying security is based on VIX Futures and it’s an European style option. What I also found is that VIX option that are a month or a few months out do not increase or decrease as much. It is more effective to trade UVXY and VXX if there are substantial open interests.
Some people argue that buying VIX PUT option is more effective, however, I would argue to sell CALL spread option instead.
Make sure to give it enough time (45-60 days) to revert back to the mean. I made a huge mistake purchasing UVXY CALL spread with only about 20 days to expiration. It turned against me and touched the exit point THE WEEK after the expiration!! In other words, the options expired on Friday and the price literally hit the exit target on the following Monday!! NEVER, EVER trade VIX, UVXY, or VXX too close to expiration.
The following videos that I found on Youtube explains pretty well about how VIX options work.
