SPY/IWM Traders - have you ever been assigned on a short option before expiration?

When we begin trading Vertical spreads, Iron Condors, and Butterflies we learn that the trades are short vega. In trading iwm options words, they benefit from a decrease in implied volatility. The opposite also generally holds true, meaning an increase in implied volatility should hurt the positions. The change in the individual options is what ultimately makes up the position profit or loss and the trading iwm options in the prices and implied volatility of the individual options are the real drivers of the position.
The point of focusing on the individual options is that the implied trading iwm options of the individual options can change in a way that benefits the position. We can visualize skew by plotting the implied volatility of individual options by strike and connecting those data points with a line.
In the Thinkorswim platform, we can see skew by going to the charts tab and then clicking product depth. Skew is static, but changes in skew over time trading iwm options trading opportunities. The table below lists the individual prices by strike and implied volatility for each option in the IWM Butterfly. What we can see is that the trade was opened on November 26th for a 1. However, the spike in implied volatility actually helped the position.
Essentially, the long option prices had increased in price more than the short options had decreased and that came from both a change in the price of IWM and an increase in implied volatility.
The implied volatility change column shows us that the biggest increase in implied volatility took place at the long strike. That change, combined with the increase at the strike, more than offset the unfavorable change at the strike. We can see that the biggest percentage change took place at the strike.
The position ended up showing an open profit largely because trading iwm options increase in implied volatility at the and strikes more than offset the loss at the trading iwm options. The point of this discussion is that understanding the implied volatility of individual options matters and can be traded. Additionally, the further we went out of the money vs the less we saw implied volatility increase.
The Butterfly trading iwm options above was not taken based on IWM Put Skew, however, an opinion about the change in skew could be traded. If we know that skew is steep and likely to flatted, we can construct a position to capitalize on that change. Different positions could be traded if you expect skew to steepen. Thanks for reading and feel free to post questions in the trading iwm options below.
I think that we should conider the values of Vega for each of the individual option strikes when opening the position, throughout the days the strategy was opened, and also when closing it. Here are some numbers using closing data from TOS. I showed this particular trading behaviour in an spanish forum http: My point in focusing on vega here was that the outcome was counterintuitive. In a short vega trade we usually expect to lose money when iv rises. This was an interesting case because the trade is short vega, but an increase in iv helped the trade.
The other greeks factor in as well, but the vega outcome is counterintuitive. Hope that helps and thanks for the comment. In my projections, it carried nearly 7 to 8 negative deltas per fly, as well as being positive theta. Thanks for the comment. I wrote the post below in response because answering trading iwm options question here would take up trading iwm options little too much space.
