cannot implicitly convert 'System.DateTime' to 'double' (CS0029)

[Cormick]

Hi Jim,

Thanks a lot for the directions and what to look for next.

I'm not sure how to formulate the expPriorDate.PriorDate[0].ToString() print,
but I'll look in the documentation and posts for the way to get it printed.

I'll be back tomorrow.

Have a good day!

Be well!

Hello Cormick,

Within the MarketAnalyzerColumn that is not displaying the date when you assign it to CurrentText, does the value have meaningful information before you assign it to CurrentText? I.E. if you print expPriorDate.PriorDate[0].ToString() before assigning to CurrentText, do you see a meaningful result in the output window?

If you change the datatype to string, does this help?

Market Analyzer DataType - https://ninjatrader.com/support/help...8/datatype.htm

We look forward to hearing from you.

Hi Jim,

I tested setting the DataType to typeof(string),
and printing the [I]expPriorDate.PriorDate[0].ToString() value before assigning it to CurrentText.

Demo Video:

https://drive.google.com/file/d/17sq...ew?usp=sharing

I set the DataType to typeof(string); in the State.SetDefault section.

It's not returning the missing dates on the Market Analyzer window.

I printed next the [I]expPriorDate.PriorDate[0].ToString() value before assigning it to CurrentText.

It does print in the Output Window

timestamp: 0:54

https://drive.google.com/file/d/17sq...ew?usp=sharing

but without the related instruments. So I can't see which instrument-s it's printing the dates for.

timestamp: 0:54

https://drive.google.com/file/d/17sq...ew?usp=sharing

I tried adding the foreach() / Print(i.FullName); loop, but it's returning errors.

timestamps:

1:09 (CS0103)
1:50 (CS0103)
2:28 (CS0030 & CS1061)
2:53
3:29 (CS0030 & CS1061)

https://drive.google.com/file/d/17sq...ew?usp=sharing

How can I add each instrument symbol to the [I]expPriorDate.PriorDate[0].ToString() value before assigning it to CurrentText?

he Hi Cormick, thanks for your reply.

It is expected those writing NinjaScript are at least at intermediate level of C# programming and are able to resolve compilation issues. Unfortunately, the support team will not be able to review or debug code for compiling errors. i.FullName is not within scope of the OnMarketData method, please see this publicly available page on the scope of variables in C#:

https://www.geeksforgeeks.org/scope-of-variables-in-c-sharp/

If you would like one on one assistance with making this script, please consider a NinjaScript consultant from the NinjaTrader Ecosystem.

Kind regards,

Hi Chris,

Thanks for the scope hint.

I corrected the code, but errors CS0030 (no doc) and CS1061 (only typos examples) remain:

protected override void OnMarketData(MarketDataEventArgs marketDataUpdate)
{
foreach (Instrument i in Instruments)
{
Print(i.FullName);
}

if (marketDataUpdate.MarketDataType == MarketDataType.Last)
CurrentText = expPriorDate.PriorDate[0].ToString(CultureInfo.InvariantCulture);
}

CS0030 Cannot convert type 'NinjaTrader.Cbi.Instrument' to 'NinjaTrader.NinjaScript.MarketAnalyzerColumns.Ins trument'


CS1061 'NinjaTrader.NinjaScript.MarketAnalyzerColumns.Ins trument' does not contain a definition for 'FullName' and no extension method 'FullName' accepting a first argument of type 'NinjaTrader.NinjaScript.MarketAnalyzerColumns.Ins trument' could be found (you are missing a using directive or an assembly reference?)

In post #28 (https://ninjatrader.com/support/foru...07#post1165507)


I got the instruments symbols return with the i.FullName variable within the foreach loop scope. Is that the block level error you referred to?
If so, why does it work for the indicator script (as in post #28 result), but not for the MarketAnalyzerColumns script?



The documentation link you shared in post #26 (https://ninjatrader.com/support/foru...69#post1165369) also shows the code usage within the foreach/block scope, not the State.DataLoaded/method scope.


For lack of a MarketAnalyzerColumns example, why then is it returning errors CS0030 and CS1061?

I also tested as set in the documentation example

else if (State == State.DataLoaded)
{
expPriorDate = myDailyBarsPriorOHLC();

foreach (Instrument i in Instruments)
{
Print(i.FullName);
}

Print("PriorDate " + expPriorDate.PriorDate[0].ToString());
}
}

but that too returns errors CS0030 and CS1061:

For lack of a MarketAnalyzerColumns example, why then is it returning errors CS0030 and CS1061 there too?

Do you have Ninjatrader 8 documentation reference that explain the solution to these errors?

If no current NT8 documentation is available, what is your solution?

If you don't know other solution than the scope error you mention, and if the scope update I made is correct, can you please ask a colleague around who might answer this MarketAnalyzerColumn problem.

Thank you.

[Cormick]

Hi Chris,

I found some more documentation and a working Print example for instruments display from the MarketAnalyzerColumns script.

The foreach loop works only for the indicator script (c.f. #28 (https://ninjatrader.com/support/foru...07#post1165507)).

For the MarketAnalyzerColumns script we must use:

Print(String.Format("{0} is being used as the input series", Instrument.FullName));

https://ninjatrader.com/support/help...injascript.htm

Thanks a lot for your help! You rock!

Market Analyzer DataType - https://ninjatrader.com/support/help...8/datatype.htm

We look forward to hearing from you.

I got some new results.

Full code:

https://pastebin.com/X102NHmx

The Output windows Prints do return the Symbols that are already displaying in the Market Analyzer window only.

I search the copied prints for RTY but did not find it in the prints.

The Prints .txt:

https://drive.google.com/file/d/1H7y...ew?usp=sharing

The prints tell us the symbols are not returned before assigning expPriorDate.PriorDate[0].ToString() to CurrentText.
Ok. But why?
What's preventing the missing symbols to display? since the non-missing symbols do display, what's causing the latter to display?

How could the prints let us know?

What's required to do next to establish what's preventing the missing symbols to display in the MarketAnalyzerColumns Column?

Once that established, how to make it display the missing symbols in the MarketAnalyzerColumns Colum?

[NinjaTrader_ChrisL]

Hi Cormick,

Do you see any errors in the log tab of the Control Center? If you do, please share those with me. If not the logic of the script is causing this to happen, in which case the script must be reduced and debugged.

Kind regards,

How to either enable them, or get them to return their prior dates?

Hi Cormick,

The Interactive Brokers connection does not have real-time enablements for these instruments. You will need to have real time, non-delayed data for the instruments you are requesting in the Market analyzer. Please contact the Interactive Brokers support team to ensure you have all of these instruments enabled.

Kind regards,
-ChrisL

Hi Chris,

Thanks for the Interactive Brokers info.

The IB print reference is the auto-connection I did not use for the test.

I tested from the Continuum sim101 account and the results gotten are from this other connection, as you can tell from the symbols names.
How to get the symbols on continuum sim 101?

[NinjaTrader_ChrisL]

Hi Cormick, my apologies, I did not see the Continuum connection below the IB connection.

The symbols are not enabled on your account. Please write into brokeragesupport at ninjatrader.com to request these instruments.

Kind regards,
-ChrisL
