eSignal-EOD vs eSignal-RT OHLC price mismatch

[psytek]

Hello,

When I compare my eSignal-EOD OHLC prices (which match QP2 data) to eSignal-RT data I find that they differ significantly.

1) Can sombody explain the difference?

2) How can I calculate OHLC prices from RT data that match the eSignal-EOD prices?

I am trying to convert EOD systems to work with RT data and need the best match I can get to EOD.

Many thanks for any help you can give,
Herman.

Hi Psytek,

If possible, it would be good to see an example of what you are referring to. Specifically the date and symbol would help us isolate any disparities between EOD and the real-time version of eSignal. As much information as you can provide will help us expedite the troubleshooting and get back to you sooner. Please let me know. Thanks.

Hello DuaneG,

You asked fro an example, here is are a few:

Yahoo 3/19/2004:

eSignal RT Open price: $44.93
eSignal/BigCharts EOD Open price: $ 46.54
Difference: $1.61 or 3.46%

Other dates that look different for this stock:
2/25/2004
3/1/2004
3/4/2004
etc.

I would like to know how the EOD is derived at, it appears to be different on many days for many stocks, mostly minor but neverheless different.

I seem unable to calculate EOD prices from RT data but would really like to do that.

any explanation would be appreciated,
herman.
