There is no way to write an EFS study that will scan hundreds of symbols. You have to do that with eSignal's API solution.
You could use the eSignal scanner to get this information or you can use any of the common sites for the financial markets (quote.com, yahoo.com or other) to get this information also.
If you are just looking for anything closing above the 52 week high, you don't need to spend any money/time trying to write it in EFS.
