IH/ADVFN Market Data Tools Q&A

[Mattu]

I spoke to 'em about the Top Lists issue.

I'm thinking disable it or set it to a particular volume threshold....

His reply:

This one is almost too easy.

There is a variable in the Toplist code []. If the
percentage change in a stock price is greater than the filter
percentage, we assume that something odd has happened like a stock
split, and remove it from the list.

This value defaults to 399% in the constructor for the Toplist class,
but it is configurable via the config file.

For the penny type stocks, obviously an change in price of a few cents
can mean a several hundred percentage change. We just need to set the
filter value accordingly.

I don't know enough about the market to know what to do. Do NO/NB stocks
have splits? If they don't then we could just disable this feature. I
bet they do though - in which case we just need to come up with a better
value for the filter percentage. Suggestions?
