Virtualmark asked: Just curious about where do you source your Nasdaq NH and NL numbers from? I'm assuming that "ND" and "OCO" are two different sources for that data?

My software tracks all exchange stocks daily, and identifies which exchange they are a part of, and then calculates the New Highs and New Lows and Unchanged daily. I purchase the daily stock information from one of the major suppliers.

As to OCO I suggest you read what this means to understand it better.

So "ND" consists of ALL stocks on the Nasdaq Stock Exchange. The "OCO" begins with this same lists and then does removals to limit the list to a much smaller number.
