IsMember Function


The ISMEMBER() function can be used to show if the underlying stock is part of the selected index (S&P500 for example) either currently, or at some time in the past.

This function requires Optuma Symbol Lists to be enabled as part of your Trader Services subscription.

In this example, ASH left the SPX in 2008, and AMZN has been in the index since 2005.
