Playback Connection Time Print Bar/Tick Time

[BartMan]

I wrote some code that was working over the weekend but is NOT working right now

Right now it prints the same time over and over and it is a Saturday of all things
isPlayBack=True CurrentTick Time=4/17/2022 3:05:00 PM

Hello BartMan,

Thank you for your post.

So that I may try to replicate on my end, are you seeing the incorrect behavior when it is used on a regular chart, or when backtesting in Playback? On what instrument are you testing? Please provide the bar type and interval as well.

Thanks in advance; I look forward to assisting you further.

Regular chart code determines if isPlayBack or not

private bool isPlayBack=false;

if (Connection.PlaybackConnection==null) { Print("--------------------------------------------------------------------------------------------------NOT Playback---------------------------------->"); isPlayBack=false; } else { Print("--------------------------------------------------------------------------------------------------YES Playback==================================>"); isPlayBack=true;

On what instrument are you testing?

• MNQ 06-22

Please provide the bar type and interval as well.

• 5Min

Hello BartMan,

Thank you for your reply.

I'm not seeing the same on my end on a normal chart when connected to a live data provider - I see it printing as I would expect on a live chart. Please ensure that you are connected to a live data provider and not the playback connection, then open a new 5 minute MNQ chart and apply the indicator - do you see the same using a fresh chart?

Thanks in advance; I look forward to assisting you further.

Kate, thank you yes indeed it works in live data. My intent purpose of this code is to print the Bar/Tick Time during Playback. As I titled the post "Playback Connection Time Print Bar/Tick Time

" that is my focus. And it worked on the weekend. I am using the Playback connector to find and resolve the errors in my code. I need the Time of the Tick where My code blows up. I do not want to write a try catch around every block of code but I cannot have a failed stop order and let my code run unprotected.

The playback connector is one of the utmost useful Ninja features, once I can reliably get the tick time of the events I must handle; it will be even better.

Hello BartMan,

Thank you for your reply.

In looking at this again, you're getting the wrong time in playback because you're using 0 as the index each time, so it will always return the time of the first bar on the left of the chart. GetTime takes an absolute index, not a bars ago index.

Try the following:

protected override void OnBarUpdate()
{
if (isPlayBack)
{
BarTime = Bars.GetTime(CurrentBar).ToString();
}
else
{
BarTime = DateTime.Now.ToString();
}

Print("isPlayBack="+isPlayBack+" CurrentTick Time="+BarTime);
}

Please let us know if we may be of further assistance to you.

+1 Kate please mark issue as resolved/complete
CurrentBar vs 0 resolved the issue!
