Consistent failure

[hemlock]

I have a consistent failure when doing the following:

1. Start version 7 with an empty workspace
2. Connect to Interactive Brokers
3. Create new chart. Add "YM 12-09", then add "^TICK" (both 5 minute interval). YM is in panel 1, ^TICK is in panel2.
4. After chart is displayed add the indicator kpTickLines to the ^TICK data series. (indicator script is attached)
5. Change the chart interval from 5 minute to 1 minute.
6. Keep alternating the interval between 5 minute and 1 minute. Usually within the first five interval changes an error will be thrown. Sometimes it says kpTickLines cannot be serialized. Sometimes it just fails. (see attached trace file).

Your script does not compile. LastBarOnChart is not a NinjaTrader property.

Sorry, that's in my UserDefinedMethods.


[Browsable(false)]
[XmlIgnore]
publicbool LastBarOnChart
{
get
{
if (!CalculateOnBarClose && CurrentBar == Bars.Count - 1)
returntrue;
elseif (CalculateOnBarClose && CurrentBar == Bars.Count - 2)
returntrue;
returnfalse;
}
}

Please provide full context for your UserDefinedMethods. Or better yet, please provide a workable script without UserDefinedMethods, thank you.

[hemlock]

Here you go.

[NinjaTrader_Josh]

Which series are you changing the time interval for in step 5? YM or TICK? How are you changing the interval too? Tool menu drop down? Data Series window? Typing 1M then 5M?

[hemlock]

Tool menu drop down

[NinjaTrader_Josh]

Are you selecting the secondary series each time before going to the Toolbar menu?

[hemlock]

No, neither of the data series are selected.

I am unable to reproduce on latest sources, but a colleague was able to reproduce on NT7B2. This leads me to believe the issue may be already fixed. Please try again on the next version and let us know if it doesn't work. Thank you.

Will do. Thanks Josh.
