Not always.

I will be dumping eSignal in six weeks, after giving them a full year
to get Tokyo data correct.  Their last trick, this month, was
inserting phantom trade dates into the data -- days when the market
was locked and closed.  This comes amid a consistent inability to get
the opening prices correct, in a market that has one and only one
opening price.  My eSignal database is riddled with errors.

Their support claimed to have fixed the problem, but a force backfill
shows otherwise.  Their support no longer even replies to e-mail.

I don't know what an "allowable fudge factor" would be for data
accuracy, but I do know two things:  1) eSignal is *way* over what
any reasonable person would consider "allowable", and 2) *much*
cheaper data sources seem to have no problems approaching 100 percent
correct.  One does *not* necessarily get what one pays for.
