I am not a fan of esignal either - DTN is worse. In 'brisk' markets (not
fast) there data lags IB considerably. I guess esignal are concidered
'cheap' (haha) compared to 'professional' feeds.
Cheers.

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.
