Hi,

being new to C# (and still using WL4 for most of my trading) I run into a simple problem for any basic programmer:

Trying to get an external symbol (VIX) from several sources in case one does not update I tried to code the following:

CODE:

I am trying to create this vix Bars object and don't know how to create a new (Bars) object in WL6/C# with the value Nothing (you see I am coming from VB.NET, and even there objects and stuff are challenging for me). Because when I tried to create it in the if {} with 'Bars vix = GetExternal... ' it did not work either as I then got an error 'vix not declared' in my last line 'DataSeries vixSMA ...' (so I assumed this was because it is behind/inside this if block?).

Thank you!

That's right. The compiler keeps track of the scope of the variable. If declared in a block then it's scoped for that block and blocks within that block.

The problem is that the variable hasn't been initialized but the code is trying to use it. You need to assign a value directly, or use the new keyword to instantiate a new Bars object. Also, using a switch/case block could help get it more organized:

Very cool, thank you!

Great to know how to only instantiate a new Bars object, and of course the switch/case looks more elegant.

One thing I don't understand is your remark:
// Calculate stop value using the Symbol Info Manager data (must be entered)

Thanks

Oh that. Disregard it. It was a copy/paste error :)
