Compiler failed to detect error

[seefisch]

I entered the following code in State==Configure place in my Custom indicator script.

if( BarsPeriod.BarsPeriodType == BarsPeriodType.Day ||
BarsPeriod.BarsPeriodType == BarsPeriodType.Week ||
( BarsPeriod.BarsPeriodType == BarsPeriodType.Minute &&BarsPeriod.Value>30 ) )
{
IsTradingHoursBreakLineVisible = false;
}
else
{
IsTradingHoursBreakLineVisible = true;
}

When I compiled it there were not compile errors or warnings.

The problem is that my script file's name did not appear in the list of available indicators. Apparently, the compiler failed to notify me of what it thought was an error.

I originally put this code segment in the State=Default because the help file states Caution: IsTradingHoursBreakLineVisible can only be set in the State=Default or State=Configure.

I moved the code segment to State=Configure and the compiler had no error and my Indicators script name appeared in available list as it should have.

seefisch,

The reason you weren't getting an error in the compiler is because your code is logically correct so it compiled successfully. However, the indicator didn't initialize correctly. That's why it wasn't on the indicator list. You can see that error in the log tab of your Control Center.

Quote from NT8 help file 8.0.0.7 Beta

When I searched the Help file for "IsTradingHoursBreakLineVisible" I got the following quote

Property Value
This property returns true if trading hours break lines are plotted on the indicator panel; otherwise, false. Default set to true.

Warning: This property should ONLY bet set from the OnStateChange() method during State.SetDefaults or State.Configure


Syntax
IsTradingHoursBreakLineVisible

I guess You have a different Help file then I do.

OMG is that ever going to be hard on us developers. I won't be able to put into the script file Print() statements to find where it crashed. I'll learn how to work with it, but my first impression is this is going be hard to live with.

seefish,

Just to clear things up, there is only 1 NinjaTrader 8 Help Guide: http://ninjatrader.com/support/helpGuides/nt8/en-us/

I think there was a miscommunication between you and quicktrick. quicktrick was pointing out that you cannot use BarsPeriod within the Confifgure state. And as you found in the help guide, you can only use IsTradingHoursBreakLineVisible in the SetDefault or the Configure state.

You can learn more about OnStateChange() here: http://ninjatrader.com/support/helpG...tatechange.htm

Hope that clears things up.

IsTradingHoursBreakLineVisible did NOT work in SetDefault

Not wanting to drag this out any longer but, that was my original reason for posting. The help file says I CAN set TradingHoursBreakLineVisible in SetDefault but it did not work for me. When I moved it to Configure it worked fine. Either the help file is wrong or there is a bug. Try it for yourself.

seefisch,

To assist you better I'll need to take a look at your indicator and test it out on our end. You can either attach the indicator to the thread or you can send an email to platformsupport[AT]ninjatrader[DOT]com with it attached.

You can export the indicator by going to Tools > Export > NinjaScript. Then you'll need to add the indicator to export by clicking the "add" button and select the indicator and click "OK". Then click on the newly added Indicator in the "Export NinjaScript" window, then click "OK".

I sent you the script file

You were unable to duplicate my observations

My indicator wroks fine.

I never know how much time to spend tracing things like this out. Hopefully I don't have unexpected problems as I further develop my script. I put it on my list of things to look into.
