Bar charts not automaticallly side scrolling

[Antraman]

Hi,

Playing around with NT6, got a few small niggly things...but firstly, my minute charts are not side scrolling, or putting it another way, the bars are not updating according to the number of minutes I opened the chart at.

Whats happening is the last bar is just going up and down, getting bigger and bigger. When I shut down and reopen NT, new bars are there, but then the last bar just keeps getting bigger again.

The time on my charts at the bottom is wrong, by a factor of hours.

Interestingly, I have a tick chart open and it IS scrolling sideways as should be, with correct time at bottom, along with BuySellPressure indicator updating.

All the other indicators on the other charts have frozen, waiting for the next bar which never comes...

Help!

regards,
Antraman

Not sure what would cause that, I have never seen that before.

- make sure your PC clock is in snyc
- which provider are you connected to?
- can you provide excat steps on how to reproduce?

Thanks

Hi,

Hmm. Went to sleep and tried again this morning, seems ok. I'm with IB.

Its happened to me a couple of times, usually closing and restarting fixes it.

The steps to reproduce are nothing more than turn on and fire up...will keep an eye on it.

cheers,

Great

Hi, its happening again. I open a minute chart (any time period), and the last bar just gets bigger, and does not update to a new bar, nor does the chart scroll sideways. Computer clock time is now 1.30pm, yet the the bar chart says 16.30. Way out.

I open a tick chart, and the time says 1.30, and the chart scrolls sideways like it should.

Both charts (minute bar and tick) show the same last traded price, that also appears in the DOM.

thanks in advance,
Antraman

So the problem is the historical chart data which is "in the future" here 16:30.

Is this reprodcible on all instrument or only on a particular one?

Thanks

[Antraman]

I also tried the ES and the NQ, both now show 16.40, same as the 6E. When I close down and reopen, the time has changed according to the length of time NT was shutdown.

I'm not sure what you mean by "in the future".

You said your PC clock did show 1:30 PM. I suppose this is the time of the timezone you are licing in, no?

So 16:30 = 4:30 PM - which is the timestamp of last bar of the bar series on chart - would be in the future, no?

[Antraman]

I am in Australia. Right now the time is 2.00am, Saturday 12th.

14.30 for me, was like 12 hours ago.

Would it be after noon Jan 12 th in Chicago right now???

[Antraman]

Just to clarify, I have set my PC clock time 12hours off, in order to coincide with what I believed to be the market opening times in Chicago, because I wanted the Session Start and Finish times in NT5 (12am), to actually start at a meaningful point rather than in the middle of the trading day, so as to have the Pivots and Prior Day OHLC indicator have any meaningful use. I now realise I have actually set my clock to the wrong time to achieve this, as I really should have the NT Session start time of 12am coincide with days open trading time in Chicago, in order for Pivots and Prior Day OHLC to work.

[NinjaTrader_Dierk]

I' confused.

- your local time is 14:00 = 2 PM at 12th (or was 13:30 = 1:30 PM at 12th)
- you last bar on chart showed (or still shows?) 16:30 = 4:30 PM at 12th, no? Please verify the timestamp of the last bar e.g. bar the chart data box.

If above is true, when the last bar has a timestamp in the future, no?

Please double check, so we are on the same page.

Thanks in advance.

The last bar of my time stamp now reads 16.45. It has not changed in the last 20mins.

[Antraman]

PC clock time: 2.13pm Jan 12
real local time: 2.13am, Jan 13
bar time stamp: 16.45 not changing

[Antraman]

I just shut down NT and started again...now last time stamp is 17.13

Price is moving up and down, but the last bar is not getting updated.

[NinjaTrader_Dierk]

Please see below: Which timestamp (plus date!) is the timestamp of your last bar on chart on?

Thanks

[Antraman]

At the time you asked, the last time stamp was 16.30. I then closed NT and restarted, and the new timestamp then was 16.45.

I closed and restarted NT now, and the timestamp is 17.45.

Date is 12th Jan.

BTW: as I posted THIS mail it was 10:53 AM chicago time.

[NinjaTrader_Dierk]

I suggest you leave your PC clock at your real local time. I'm not sure if IB internal client<->server communicaiton is able to handle what you want to achieve.

Regards

[Antraman]

It worked (for a long time) OK in NT5, and it also worked in NT6. Its just that there have been several occasions where this freezing of the last bar has occurred, in both NT 5 and 6, so I don't think it is related to internal clock time.

Anyway, the tick chart is showing the correct PC clock time...and updating each tick.

cheers,

The issue is related to downloading historical data from IB's servers. This is supported for minute and daily data but not for tick data -> that's why you experience the problem not on tick charts.

[Antraman]

OK, so issue must be IB's end, not me or NT, right?

I am using NT6.0.0.5 and TWS 865.7

Any known issues with this combination?

cheers,
Antraman

[NinjaTrader_Dierk]

Ther is no issue with your combination of NT and TWS. Just leave the PC clock at your real local time and you will be fine.

[Antraman]

OK, I adjusted the PC clock to local time then rebooted PC.

NT bar charts now seem to be working OK. Call me pig-headed, I am not yet convinced that was the solution to the problem - perhaps it was the rebooting..anyway I will monitor it and keep you posted of any developments. Sorry for all the time wasting.

cheers,
