Strategy disappeared after an error, strategy is not visible

[NinjaTrader_Gaby]

Hello Triple_M,

I would search in the NinjaTrader 8 folder for any Slope_of_MA and MA_Differences files and delete them.

If these are indicators, they should only be in the bin/Custom/Indicators file folder.

If after doing so, you are still having issues, I would recommend a clean install.

Please let me know if I can assist further.

I have setup a new clean system as described above. I also found the indicator issues and solved them. The strategy file "MyDance15min110324" does compile. The .cs file is in the right folder. It is visible in the Editor. BUT STILL NOT VISIBLE in the chart !!! and not possible to chose.

Hello Triple_M,

Are there errors appearing on the Log tab of the Control Center when opening the Strategies window?

[Triple_M]

Yes !!! Error on calling OnStateChange method: Object reference not set to an instance of an object

[Triple_M]

GOT IT !!!!

thats the code causing the error......

previousAccountBalance = Account.Get(AccountItem.CashValue, Currency.UsDollar);
BaseOrderQuant = 2; // This will be set based on account size in OnStartUp() or OnBarUpdate() when a new day/session starts.
CurrentOrderQuant = BaseOrderQuant;

the definition on the second line BaseOrderQuant = 2 ..... causes the error... hmmmm and why?

Probably because the Account.Get function is called to early, i moved it to State.DataLoaded, that works !!!!

THANK YOU Chelsea, that was the helping hint, sorry for so much confusion!
