Liquidity refers to how frequently a security trades. Many securities on the CDNX and OTCBB exchanges trade only a few times a month. If you want to include only liquid securities in your search, this feature lets you filter out securities that are infrequently traded.

It is advisable to use a value less than 100%, because even the most liquid security could be halted for a day, therefore causing it to fail the test and be filtered out.

Trading Activity:

This selection specifies the percentage of time that a security must trade during the look back period. Stock Filter does not apply any volume criteria to this filter, only that it traded at least one share.

Look back Period:

If you want to include securities that have recently started trading, you should shorten the look back period to 15 or 20 days because if a security has not traded the minimum number of days, it will fail the test and be excluded.
