but you can’t ‘zoom-out’ and have it fit in a window all nice and proper like.
Is attached what you mean … see date in bottom left hand corner … Monday, so 3 days worth of data showing for 1 second on 200k bars … which is correct for 3 x 24 hour days.
I know it’s early and my coffee has not worked through yet, but why am I misunderstanding what your problem is? 🙂

I think it’s because I had quite a bit more 1sec data historically, or so I thought, I’ve not pulled the calculator out lol to see if I’m trippin’ but when I compare multiple indexes it’s a mess and I’m not sure if it’s custom time zones underneath impacting or else.
So, I’m a WIP atmo, when last week and a bit it was all G.
Come to think of it, it was the inclusion of weekend data that hoses the amount of 1sec viewable. If you ‘uncheck’ this you see more 1sec but without the Saturday mornings close. It was a trade off and it was this I ticketed, from memory.
So it is SOP and I’m barking mad 😛
I am starting to wonder IF I’d not seen / used 10sec charts as a trade off but the more I’m thinking about it, it’s the weeks closing session (sat morning), that’s causing it.
Have a look and see if what I’m seeing or am I crackers….ha!
edit: a quick test shows same data here, which wasn’t what I saw when ticketed.
There’s also the issue that I can’t limit DAX and FTSE to there close time on v12.

if so, does that mean you have data going back a little further
Below done at 10.45am 9 Feb 24
- Select 200k bars and Mon 5 Feb 23. 32 shows.
2. Scroll / zoom out and Fri 2 Feb 19.21 shows
platform doesn’t leak to death.
v12 performs fine for me … I am not aware of RAM leakage, I have 16 GB RAM.
How many Charts do you have open at any one time when you experience leakage?
I would try and duplicate same on my Platform to see if I get leakage under same conditions as you?I’m still unable to kill-off DAX session at 22.00 as I used to
What does above mean?
If you have a Chart showing DAX, do you mean you can’t close the Chart?
OR
Are you referring to an Algo and the code below doesn’t exit / close open trades?1DefParam FlatAfter = 2200001 user thanked author for this post.
May it help anywhere :
- 200K data can’t be in one window (viewport). Possibly this depends on the monitor’s resolution, but over here it can’t (resolution-width is 2560). Btw, see below for 1M bars 1-second data in V12 (PRemium).
- When you load 200K bars, and assumed of 1 second, then more will be added on the fly. Thus, leave your platform and particular chart open for 18 hours, and 18x60x60 will have been added to the 200K.
Further, although the data is cached at fetching it (it is read in chunks), there is no storage space other than internal memory where bar data is stored. It is Java which applies the fetching.
But as GraHal told/implied, with a theoretical 86400 seconds in a day, you won’t get more than 3 days anyway. Something else is : I have a quite strong feeling that less liquid Instruments may receive more data in seconds (bar is one second) because not every bar contains ticks (hence data). I have not sorted this out yet.
Another fact (as it seems) is that things are relatively collapsing when backtesting with “seconds” data. And for IG this is far worse than for IB, already because IG generates 10x more ticks within a time period. Anyway, backtesting with 200K seconds data is relatively undoable, while with the same amount of 1 minute data, all is (again relatively) fine.1 user thanked author for this post.
