Is it possible to create an alert for an entire watchlist? Like say I have a watchlist containing 20 stocks. I want to be alerted anytime one of those stocks crosses above the 75 line on the RSI indicator. I know how to do it one by one but I just want this to be done continually for the entire list.

The feature is called Market Analyzer.
Open a new Market Analyzer, add the Instrument List that you want to scan as rows, add your Indicators etc. as columns.

Then use the following videos for either:

a) Creating-Alert-Conditions
for alerts that you want to create for your Analyzer

b) Creating-Cell-Conditions
for cell conditions that you want to add to the Analyzer

c) Creating-Filter-Conditions
for filtering your Analyzer
