Post From: Differences in bars from historical SC data feed

Hi,

I am still in final evaluation phase. And although I followed all the instructions I don't understand why I have such differences in the historical chart vs intraday chart, both daily, both from SC Historical Data Service. There are occasional strange hiccups.

You mention here
Historical Chart Prices: 12.1 - Historical Daily Bars Session Times and Evening Session Trading
that US stocks only show RTH trading hours, which is exactly how I want it to be. I also cross checked that with the global symbol settings that only RTH is shown. And also with the Session times in Chart settings.

But then I do not understand the differences shown here for IBM from historical to intraday. If at all the historical daily should have higher highs respectively lower lows, if it would have been from a 24 hour session, which it isn't. But not vice versa.

The same applies to ATVI.

Is there something wrong with the historical tick data in these cases? Redownloading etc. was not helpful.

Edit : This seems like a similar issue

Although I have no evening sessions enabled, this all "happened" during RTH here

Many thanks
