Can't save template for indicator - XML error message - locks up certain charts?

[JohnS52]

Hello -

I think this is a fairly simple indicator but I cannot save a template for it, and it won't save in a chart template or workspace template either. When I try and save the indicator template I get the attached XML error message.

Can you look at the code and tell me 1) how to resolve this problem and 2) if the code can be improved? It appears low on the list on the NS Utilization Monitor, even when on six charts, so I don't think it's a resource hog. On the other hand, it seems to lock up my MES charts and may be the cause of a terrible data lag for MES (but no other instruments, including ES, M2K and MNQ).

I am using Dimension4 to sync my computer clock every 5 minutes but my Data Lag Monitor for MES is reading 19.9 minutes.

Thank you in advance for any help.

Hello JohnS52,

Thank you for your post.

Have the inputs in this indicator been properly serialized? Make sure any brush properties have the [XmlIgnore()] attribute.

Below is a link to a forum post that has an example of a properly serialized input.

Hello,

You are missing the following using statements:

using System.Xml.Serialization;

using System.ComponentModel;

Please add those to the using declarations section and recompile.

That worked perfectly. Thank you so much!
