<FONT face=Arial
color=#0000ff size=2>I was trying to use eSignal to see if I could have a RT
provider and do EOD trading with it and experiment with intraday stuff.. It got
to be a mess as stated so I dropped it and continue to use TC2k for EOD
trading.

Does your eSignal data match your QP2 data???
D,
You mean you don't use RT or EOD anymore or you found another data provider?
Or did you give up on trading? ;-)

<FONT face=Arial
color=#0000ff size=2>Not sure this will help but I tried a similar thing
several months ago and found big errors in the data supplied by eSig.
One such error was a gap in the data several months back for
IBM of all things. I couldn't believe that it hadn't been
corrected. I started finding a lot of other things and got frustrated
and gave up.

<SPAN
class=531415316-15032004>Hello,
<SPAN

I run both
eSignal and QP2 data and am porting some mature QP2 EOD code to
eSignal to see if it can be enhanced with RT data. Before changing any
code I wanted to confirm identical EOD performance in both data
environments, I found huge discrepancies. Comparing daily OHLC prices
derived from eSignal RT data with OHLC data from QuotePlus I found that
taking a Random 20-day sample showed 38% disagreement between the two data
sources. Now the question arises as to which is the correct
one?
<SPAN
class=531415316-15032004>
If you have
both data sources please let me know if you have noticed this discrepancy.
I used the following code snippets to illustrate this problem. I used two
separate AB instances; one configured for eSignal and one for QuotePlus.
Perhaps I am doing something wrong....I hope so!

Many thanks
