Free charts and backtesting of over 500 stock market indicators, including breadth, put/call ratios and volatility

About the Charts allows you to create charts in 3 different ways:

You will notice that we have added Standard Deviation markers to all charts where an indicator has been requested. These markers are absolutely essential in determining how high (or low) an indicator's value has to be before you can expect a market change. The mean and standard deviation values for an indicator are calculated using the indicator values for the range in question. For example, if you request a 3 month chart, then the mean and standard deviation will be based on 3 months of indicator readings. For an overview of the indicators we calculate, please navigate to the indicators page.

All charts are usually updated before the US market open around 6:00am ET (or 11:00am GMT).
