error CS0118 NinjaTrader.NinjaScript.Indicators.SMA is a type, but used as variable.

[akushyn]

Hello, I am implementing indicator.
And I get error everywhere , when I compare close[0] and value of SMA() indicator.
What can be a problem?

The weird is that when I am using indicator - everything is fine.!
But when I try to export I get error in log file.

private bool current_trend_filter(AkSignalType signal_type)
        {
            bool result = true;
            switch (signal_type) {
                case AkSignalType.Buy:
                    if (Close[0] < SMA(SlowSMAPeriod)[0])
                        result = false;
                    break;
                case AkSignalType.Sell:
                    if (Close[0] > SMA(SlowSMAPeriod)[0])
                        result = false;
                    break;
            }

            return result;
        }

Hello akushyn,
Thanks for your post.

The issue does not appear to be with any NinjaScript in this snippet.

If you exclude this script from compilation are you able to export?

Hello, JoshG

Thank you for the quick reply.
So far, I have no other scripts in the scope.

Could it be the issue with VirtualBox running NT8 export?

[akushyn]

I've just tried .... create copy-paste SMA indicator as my custom indicator to try exporting the script.
But indicator is avaliable only in Script Editor and not visible to add on chart or export.

See attached picture.

akushyn,

Your NinjaScript does not appear in the Indicators window because of your "Name" property inside OnStateChange()

Can you find the NinjaScript once you change that property to the name you expect to find it under?

When I comment Description and Name properties the indicator appears in the list.


And I think it is a BUG with general question about exporting ERROR - can't export scripts from Virtual Machine.

I've just copied to another notebook with Windows7 (not a virtual drive) and export works like a sharm.
So, may be you can advise me some topics, how to run NinjaTrader8 on Linux Mint 19 ?

akushyn, I do not believe that this is a bug. I am able to compile my own custom method just fine when using the same logical comparison. ( Close[0] < SMA(SlowSMAPeriod)[0] )

For anyone finding this post a few years later, I hit a similar issue today whereby often used indicators like EMA or ATR in existing strategies started throwing compile errors but only in certain batches of files. The issue for me was the parent folder name somehow clashing with the strategy name. For example, I created a folder within Strategies called MyStrat and then within that had a strategy named MyStratv1. If I renamed the folder to RandomStrat, the compile errors went away. There must be some special namespace pattern matching that happens under the hood that breaks references to these indicators when the folder name is too close to the strategy name.
