32 seconds left in 30 second chart

[ATI user]

this morning I am running a 60 sec chart with my strategy and 30, 15 and 5 sec charts with no strategy

all charts are running an indicator that uses the following code to plot seconds remaining in each bar

TimeSpan barTimeLeft = Bars.Get(Bars.Count - 1).Time.Subtract(Now);

the indicator runs fine in the strategy 60 sec chart(where it is being added by the strategy)....in all others it shows more time than the bar interval....for instance at the start of each bar in the 30 sec chart it shows 32 secs...in the 15 it shows 17 secs....in the 5 sec it shows 7 secs

how can this be? ydy is was working perfectly and this morning in Market Replay fine

I am connected to Zenfire as is one of my users who is having the same problem

is this a data feed server problem this morning?

thanks

ATI user,

Please try resyncing your PC clock and restarting NT. When using the BarTimer indicator you will always need to ensure your PC clock is in sync.

thanks Josh

fixed the problem even without NT restart

my comp is set to automatically sync with Internet Time....any idea how it would get out of sync?

[NinjaTrader_JoshP]

PC clocks are kept via your computer. Some motherboards have bad CMOS or CMOS batteries and when the computer is turned off the clock tracking cycles are not kept perfectly. When you turn it back on it can be out of whack a few seconds after a night. Other people may experience poor clock tracking even with Windows on and will just have to sync it every once in awhile.

In a nutshell, PC clock is tracked by hardware and there is nothing we can do to assist in this matter.

thanks

here is freeware to sync automatically if anyone is interested...seems to work fine

Thanks ATI user, very convenient.

Not doing well this morning

I have manually synced the clock several times and restarted NT several times thereafter and I still am getting more seconds in the chart than the interval of the chart

any other solutions?

thanks.

ATI user,

All I can suggest is for you to ensure the PC clock is synced. BarTimer compares the timestamps of your bars with the time of your PC clock to determine the time left. When they are out of sync you will get erroneous readings.

[ATI user]

how can I check if synced...after i manually sync

the bars are all stamped the right time...for instance, the 5 second chart has all bars stamped on 5 or 0 seconds...so NT is plotting/stamping correctly

the problem is that, on an intermittent basis now, the time code says there are 7 seconds remaining in a 5 second bar...which would be from comparing the PC time to the bar stamp...how the PC clock can be off by 2 seconds after manually syncing to time.windows.com is beyond me...unless NT is using a different time server that is out of sync with time.windows.com.

Please see the attached list and tell me if NT uses one of there servers...if not ....which one so I can sync to it....3 of my users are using time.windows.com and all have the problem....one is synced to time-a.timefreq.bldrdoc.gov and has the problem

I am not using the NT indicator 'BarTimer'...rather I am using the code:

TimeSpan barTimeLeft = Bars.Get(Bars.Count - 1).Time.Subtract(Now);

where barTimeLeft is returning 7 on a 5 second bar chart

ATI user,

Use DateTime.Now and print when a new bar starts. They should be in increments of 5 seconds.

[ATI user]

if ( FirstTickOfBar )
{
Print("*** DateTime.Now "+DateTime.Now );
}

yields the attached from a 5 second chart

[NinjaTrader_JoshP]

Remember this is not a scientific approach. FirstTickOfBar can be any time within those 5 seconds. In a liquid market you should be able to get a general overview picture of the sync though.

right...thanks....FirstTickOfBar is not want I want to check sync...especially on the YM around noon

here is my problem:

OnBarUpdate executes on every tick. How can the following code, at any time, return secondsRemaining = 7 if the PC clock is in sync?

TimeSpan barTimeLeft = Bars.Get(Bars.Count - 1).Time.Subtract(Now);
secondsRemaining = barTimeLeft.Seconds;

Regardless of what time the tick comes into the bar, there can not be more than 5 seconds remaining in a 5 second chart...and certainly not 7 seconds if the PC clock is in sync...no way it can be out by 2 seconds ever

[NinjaTrader_JoshP]

As mentioned, BarTimer checks bar timestamp against your PC clock. It doesn't care what the time on the ticks are. Your PC clock is not in sync with the data you have and that is why you are seeing discrepancies. Whether this is an issue with your PC clock or an issue with the timestamps on your data, there is nothing NT can do. All I can suggest is for you to sync your PC clock. If the auto syncing isn't cutting it, do a manual offset to sync it yourself. You can also try deleting your data and reloading new ones.

how will deleting data work? I am on live feed. Does saved data affect the timestamp?
