// The data feed decides when to reset the daily high and low prices.  We
// maintain the high and low bid and ask values, and similar data, ourselves.
// We want to reset these at the same time as the data feed resets the high
// and low prices.
//
// This is mostly obsolete.  Some of this was based on when we left things
// running overnight.  However, a few alerts still use it.
//
// This will signal its listeners when when we think the new trading day
// has started.  Currently this is implemented by looking for the first print
// during market hours.  This is based heavily on eSignal, which didn't reset
// some of its data until the first print.  We use the daily high field to tell
// us when we see the first official print.
