I've been interested in bad data ever since - about 4 years ago - I and 3 of my
online friends compared MCO numbers - and we each had different numbers (and
different data vendors). Turns out not a one of us had the correct number. And
the most technical of us (the engineer) said - how can I ever risk money on the
basis of systems which are developed or traded using faulty data.
At this point - I only get about 5-6 important data streams now (i.e., the ones
that are in my systems) - and I check them out on a random but routine basis.
Frankly - I don't know how people who download 2000 stock prices a day could do
that. Robyn
