Historical data in live looks wrong

verygrubby · Sat, 02 Jan 2021 10:39:41 +0000

Morning all, and Happy New Year! I’m having some issues with the historical price data in the live platform. When I look at anything older than a couple of months, there seems to be an issue with Friday night/weekend data. eg when I look at the Dow Jones Friday evening data, I would expect to see the data stop at approx 22:00 on Friday night, and restart at 23:00 on Sunday. Indeed, that is what I see on the demo platform. However, on live, the data often carries on through Friday night, into Saturday morning,then it jumps to the early hours Monday (missing out Sunday night data). Take Friday 25th September 2020 for example. 1st picture attached is the same date for the Dow – approx 19:45 to 22:00. Demo vs live. The charts are totally different. The 2nd attachment is the same date from live, looking at the data after 22:00 on Friday 25th September – you can see is carries on through Friday night, into Saturday morning, then gaps up at 3am Saturday morning into 4am Monday morning! 3rd picture is the demo platform for this date, showing the data stop at 22:00 Friday night, and start again at 23:00 on Sunday, as expected. Obviously, all settings are the same on both (same time zone, display weekend data checked, 1m charts on both, etc) What am I missing here? Many thanks

I’m only asking to make sure we assign the correct priority in the Wants & Bugs List (PeterSt) as the priority (hopefully) will determine what order PRT works on our current list of 49 Wants & Bugs.

It’s in all our interests to make sure the assigned priority is realistic and based on user hindrance to making profits.

I’ve seen many examples on numerous instruments.

It seems to affect the earlier portions of a long backtest (eg 200k bars or 1m bars) – so on a 1minute chart that would still be quite recent, but on a longer timeframe chart it could be years ago.

@verygrubby please can you make this Topic – Not Resolved ?

Currently it is showing as Resolved which is at odds with the Priority 2 on the Wants & Bugs List (PeterSt) and we don’t want to confuse PRT when they refer to this Topic for more detail on the problem.

FYI I tried to mark it as “unresolved”, but can’t….
