Opening Bell indicator NT8 - IsFirstBarOfSession not working?

[darthy]

Is it possible or easy to convert to ninja7?
thanks!

Hello SBMT17,

With the help of NinjaTrader_AlanP, I got the OpeningBellAlert indicator working. I have attached the file here. You need to import the indicator to NT8 by Tools->Import->Ninja Script Add-On then choose the .zip file. The indicator sound is default to NT Alert1. If you prefer exchange opening bell sound, I have attached the OpeningBell.wav. You can copy the sound file to NT8 sound folder at Program Files (x86)\NinjaTrader 8\sounds.

To use the indicator, add it to Daily chart or any intraday chart. There are three user input fields if you want to change them:

1. Sound file is default to Alert1. You can click on it and pick any .wav file you want (OpeningBell.wav)
2. Rearm alert is default to 32400 seconds (9 hours), change it to any value that you want
4. Enable Alert is checked. Uncheck if you don't want an alert.

Cheers

Hello darthy,

This could be created for NinjaTrader 7.

However, the attributes for public inputs are different for NinjaTrader 7, and unfortunately, not documented.
The Bollinger indicator NumStdDev property has a good example of what the attributes for NT7 look like on lines 78 through 80.

Further, if you want just the time without the date, a TimeSpan can be used instead of a DateTIme.
Below is a link to a forum post with sample code.

That said please note, NinjaTrader 7 is no longer in active development and we are no longer considering new feature requests or changes for NinjaTrader 7. Main development has shifted to our flagship platform NinjaTrader 8. This does mean updates from brokerages, data feeds, or operating systems that require an update in NinjaTrader will not be implemented in NinjaTrader 7 and may cause an interruption in service.

While there is not a set ETA for the complete discontinuation of NinjaTrader 7, we highly recommend transitioning to NinjaTrader 8 as soon as possible before NinjaTrader 7 reaches its end of life to prevent interruption of service.

Hello,

Been using this indicator PlayAlertWhenTimeIsUserInputtedTime.zip with the opening bell file. However since updating to the latest version of NinjaTrader. There is no longer an alert tick box option inside of the Properties of the PlayAlertWhenTimeIsUserInputtedTime.zip indicator.

Also all the original NinjaTrader alerts within the > Program Files (x86) > NinjaTrader 8 > sounds folder are all missing. Only the custom sounds are available.

Can you please advice?

Hello Chingchongforum,

Welcome to the NinjaTrader forums!

The installation folder for 8.0.27.0 has changed to C:\Program Files\NinjaTrader 8\.

From the help guide release notes:
"Attention 32-Bit Users:
64-bit has become the standard for applications in the Windows environment
As we continue to modernize our desktop platform and clearing up performance related confusions around 32 vs 64 bit NinjaTrader Desktop usage
NinjaTrader 8.0.27.0 will be solely a 64-bit Windows application, this means the installation directory will change from C:\Program Files (x86) to C:\Program Files"

https://ninjatrader.com/support/helpGuides/nt8/8_0_27_1.htm

If you are referring to the example on post # 7, this only has one property in the code 'TimeTogglerForUI' which is a DateTime object.

Thanks for your reply NinjaTrader_ChelseaB. I've managed to find the sound files with the path you showed.
I'm still stuck with the PlayAlertWhenTimeIsUserInputtedTime indictor not playing the Openingbell.wav sound since updating. It was fine before. Can you please assist?

Hello Chingchongforum,

Use Print() to understand the behavior and debug.

Print the time of the bar, print the value of the State property (so we can ensure the bar has closed in real-time), and all values used in the condition.

Are you seeing the condition has evaluated as true in real-time?

Below is a link to a forum post that demonstrates using prints to understand behavior.

So, does anyone have a working opening / closing bell indicator that they would be willing to share? I tried making my own, no dice (incompetent when it comes to coding). Also, I read thru the older related posts…to fragmented.

TIA

Hello tomturn,

Welcome to the NinjaTrader forums!

The OpeningBellAlert indicator posted by in post # 8 is working on my end without issue.

Below is a link to a video of a test of this
https://drive.google.com/file/d/1n1I...usp=share_link

This is only the opening bell which is found when Bars.IsFirstBarOfSession and IsFIrstTickOfBar are both true.

The close of a session would be a bit more complex, as OnBarUpdate() would not trigger until the open of the next session when the end session bar closes. Instead, it would be possible to check the time of each MarketUpdate to be after the .ActualSessionEnd when using a sessionIterator in OnMarketData().
