Something is wrong with your config, but without more information who can say what it is?

How is it possible that [] operator is not supported? i don't get it.
How do i get to see the value? it makes debugging almost impossible The [] Operator in this case means the debugger doesn't recognize the individual array elements. I don't know how to get the VS debugger watch list to let you look at specific elements of an array, or if it is even possible. I asked this a long time ago and got no answer. This is what I do to work around that. Create a persistent variable, assign it to the value of sc.Close[sc.Index] and add the persistent variable to the watch list. You can use a regular variable, but if you want to only break when the value changes, it will always reset each time the study is called. With a persistent variable you won't have that problem. float& ClosePrice = sc.GetPersistentFloat(0);
ClosePrice = sc.Close[sc.Index]; |

Nice catch, hadn't spotted it was being used in a 'watch', had assumed 'autos' or 'locals'.

To get the VS Debugger to show the values of an array or vector you can add the following after the variable in the Watch list: + offset, count Where 'offset' is the number of items to skip forward and 'count' is the number of items to display. You can omit the '+offset' and just use the ', count'. For example, if you want to display items 101 - 110, you could add '+ 100, 10' after the variable in the watch list.
