Tomasz I did created a new EOD eSignal data base and i found that (over the same
20-day random sample) QP2 and eSignal data were exactly the same using EOD, the
problem i have is with the RT data conversion to EOD prices using only
the eSignal RT database.
<FONT face=Arial color=#0000ff

Also,
as you suggested, setting AA Settings to the Daily
mode <FONT face=Arial
color=#0000ff size=2>gave EOD prices that matched the OHLC extracted from RT
data, but they do not match either QP2 or eSignal EOD data - this suggests that
either my code is wrong or RT data is different. When setting the AA
to Minutes and using <FONT color=#0000ff
size=2>TimeFrameGetPrice(<FONT color=#ff00ff
size=2>"O", inDaily, expandFirst ); to
extract EOD prices from eSignal RT data this gives me different
prices from both QP2 and eSignal EOD data.

Any suggestions on how <SPAN

RT will be appreciated.

Herman,
Did you do what I suggested ? I.e. creating eSignal database
with base time interval set to "EOD (daily)" ?

Subject: [amibroker] Does your eSignal
data match your QP2 data???
<SPAN
class=531415316-15032004>Hello,
<SPAN
class=531415316-15032004>
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 for
any comments you can make,
