One of the problems in charting CHDO and many othe

One of the problems in charting CHDO and many other penny stocks is that there is insufficient data upon which to base a statistical analysis and thus a chart can be terribly misleading.

Take today's truly remarkable market action (please).  There were three trades.  One for $3.12, another for $1.54 and the biggie of the day for $12.50. Total for the day was $17.16, all @ .0125.

In the previous 10 days there have been two additional days where CHDO traded less than $50 and  two other days where there ZERO trades. How could anyone build a reliable chart on data like this?

(I wonder if there was any other stock in the entire US group of listed securities, all markets, that if it traded at all today, traded less than seventeen bucks worth?)
