The Thinkorswim volatility chart is a powerful tool for options traders, providing real-time data on the volatility of underlying assets.
To start using the chart effectively, you need to understand the different types of volatility it displays, including historical volatility and implied volatility.
Implied volatility is calculated by the market, taking into account the price of the option and the underlying asset's price, while historical volatility is based on the asset's past price movements.
By comparing these two types of volatility, you can gain insights into market sentiment and potential price movements.
Volatility Measures
Volatility Measures are a crucial aspect of trading, and thinkorswim's volatility chart provides valuable insights into a stock's price movement. The chart displays two main measures: IV (Implied Volatility) and HV (Historical Volatility).
IV is calculated from the prices of currently listed options and is expressed in annualized terms. It can range from near zero to near 100%. For example, a stock might have an IV reading of 33.77%, indicating that the options market is pricing in about a 34% variability around the current price.

The 52-Week IV High/Low is a useful metric, showing that over the last year, the stock has seen IV as high as 72% and as low as 14.7%. This gives you a sense of the stock's volatility over time.
The Current IV Percentile is another important metric, indicating that over the past 52 weeks, IV was higher than 33.77% (the prevailing IV) 67% of the time. This suggests that IV is relatively low in this stock right now.
IV is a forward-looking measure implied by the options market, while HV is backward-looking. HV is a moving average of actual price variability in the stock over the previous 52 weeks.
The 52-Week HV High/Low is a useful metric, showing that over the past year, the stock's HV has been as high as 68% and as low as 15.2%. This gives you a sense of the stock's volatility over time.
The Current HV Percentile is another important metric, indicating that at 29%, the current HV reading is a little lower than the current IV percentile.
Here's a summary of the key differences between IV and HV:
By comparing IV and HV, you can get a better sense of how much expected volatility is being priced into options versus how much volatility actually tends to materialize. If IV is lower than HV, it may suggest that options are inexpensive, while a higher IV relative to HV may suggest that options are expensive.
Thinkorswim Chart Setup

To set up a thinkorswim chart, you'll want to start by selecting the correct study and indicator. This can be done by clicking on the "Studies" tab and browsing through the available options.
The thinkorswim volatility chart is typically set up with a 50-period simple moving average (SMA) as the base. This helps to smooth out price movements and provide a clearer view of the overall trend.
By default, the chart will display a 14-period relative strength index (RSI) indicator, which can be used to gauge overbought and oversold conditions.

How to Set Volatility on Charts
To set volatility on charts in Thinkorswim, right-click on the graph and select "Studies", then "Edit Studies." In the column "Lower", add "HistoricalVolatility" and click "Add selected" to edit the settings.

Historical volatility displays the difference between the highest and lowest price of an asset as a percentage of the asset price. It's a necessary characteristic to understand the value of an asset.
To add implied volatility, follow the same steps as historical volatility and add "ImpVolatility." This will display the projected volatility as a percentage of the asset price.
Implied volatility is often different from historical volatility, and in classic option trading, it's believed that if implied volatility is lower than historical, you should buy options, but this isn't always the case.
Options Trading Strategies
Options trading strategies can be influenced by volatility measures, such as the IV percentile. A high IV percentile can indicate relatively high options premiums, making short options strategies like short vertical spreads a good option.
Options premiums are relatively high with a high IV percentile, making it a good time to use short options strategies.
Short vertical spreads can be a useful strategy when options premiums are high, allowing traders to profit from the difference between the two strike prices.

This strategy can be used with various products, including stocks, ETFs, and indexes.
A low IV percentile, on the other hand, can indicate relatively low options premiums, making long options strategies like calendar spreads or long vertical spreads more suitable.
These strategies can be used to profit from the difference between the two strike prices or to hedge against potential losses.
Regardless of the strategy, options statistics can help traders track volatility and make more informed trading decisions.
Each investor should review their investment strategy before making any investment decision, as options trading strategies may not be suitable for everyone.
Understanding Volatility
Volatility is a measure of how much the price of a stock or option is likely to fluctuate. It's a key concept to understand when using a thinkorswim volatility chart.
Thinkorswim's volatility chart displays the historical volatility of a stock or option, which can be calculated using various methods, including the standard deviation of daily price changes.
A high standard deviation indicates that the price of a stock or option has been more volatile in the past. For example, a stock with a high standard deviation may have experienced large price swings due to market events or news.
The thinkorswim volatility chart can help traders identify potential trading opportunities by highlighting periods of high volatility. By analyzing these periods, traders can make more informed decisions about when to enter or exit trades.
Volatility can be influenced by various factors, including market sentiment, economic indicators, and company-specific news. For instance, a sudden increase in volatility may be due to a surprise earnings announcement or a major market event.
The thinkorswim platform provides various tools and features to help traders manage volatility, including stop-loss orders and position sizing.
Thinkorswim Chart Customization
To customize your Thinkorswim charts, start by right-clicking on the graph and selecting "Studies", then "Edit Studies". This will allow you to add new studies to your chart.
Historical volatility can be added by clicking in the "Lower" column and selecting "HistoricalVolatility", then clicking "Add selected" and editing the settings icon next to it.
Implied volatility can be added in a similar way, by selecting "ImpVolatility", "Add Selected", and "Ok". This will give you adjacent charts measuring volatility as a percentage of the asset price.
The implied volatility is often different from historical, and in practice, it's not always clear what to do. Beginners may find that if ImpVolatility is lower than historical, they should buy options, but this is not always the case.
To avoid errors, double-check accuracy by hovering and comparing data on different graphs. This will help you ensure that the chart is not distorted, making it seem like one volatility is bigger than the other when it's not.
Trading with Technical Analysis
Trading with Technical Analysis is a powerful way to make informed decisions on the thinkorswim volatility chart. Average True Range (ATR) is a key indicator to consider.
Using ATR helps you gauge volatility, which is essential for trading on the thinkorswim platform. ATR measures the average range of price movements, giving you a sense of how much the market is moving.
To use ATR effectively, you need to understand how it works. Average True Range (ATR) is calculated by taking the true high and low of the day and subtracting the previous day's close, then averaging the result over a given period.
By incorporating ATR into your trading strategy, you can better navigate the thinkorswim volatility chart. This will help you identify potential trading opportunities and avoid false signals.
The thinkorswim platform provides a range of tools to help you apply ATR to your trading. You can use the ATR indicator to set stop-loss levels and take-profit targets based on the average price movement.
By combining ATR with other technical analysis tools, you can gain a deeper understanding of the market's behavior on the thinkorswim volatility chart. This will enable you to make more informed trading decisions and potentially increase your chances of success.
Volatility Chart Settings
To add historical volatility to your chart, right-click on the graph and select "Studies", then "Edit Studies". In the "Lower" column, add "HistoricalVolatility" and click "Add selected" to edit its settings.
Historical volatility displays the difference between the highest and lowest price of an asset as a percentage of the asset price. It's a necessary characteristic to understand an asset's value.
To add implied volatility, follow the same steps as adding historical volatility and add "ImpVolatility" to the "Lower" column. Click "Add selected" to edit its settings and get the chart displayed as a percentage of the asset price.
Implied volatility is often different from historical volatility, and it's not always true that if implied volatility is lower than historical, you should buy options, and if it's higher, you should sell. This is a common misconception among beginners.
To avoid chart distortion, you can transfer two volatilities to one chart to save space, but be aware that it may seem like one volatility is bigger than the other when it's not. Double-check the accuracy by hovering over the data and comparing it on different graphs.
