static PriceGrab getInstance

I hate static

Its the singleton pattern used to avoid multiple object creations

I know

Looks useful; but.. Why would you make a singleton without a defined constructor :E?

 

The purpose of singleton is to prevent multiple instances, hence a private constructor.. and the only reason u would do this is in cases where the class holds some sort of reference that should not be created multiple instances of; like a connection. But you create a new one every time anyway?

 

also, is this on purpose?

final String AVERAGE = "average",LOW= "recent_high", HIGH="recent_low";

HIGH = low and LOW = high?
