Error

I had a totally working code. Now the code keeps giving me this:

**NT** Error on calling 'OnBarUpdate' method for strategy: Sequence contains no elements

Hello,

Your NinjaScript / C# Code will always be logically processed and evaluate according to your set logic – this can of course lead to unexpected results at times, thus we would suggest to simplify and debug your code to better understand the event sequence it would go through - if you would like please post an example script which replicates the error mentioned so that we may examine it

First of all you would want to use Print() statements to verify values are what you expect - Debugging your NinjaScript code.

For strategies add TraceOrders = true to your Initialize() method and you can then view valuable output related to strategy submitted orders through Tools > Output window - TraceOrders

It may also help to add drawing objects to your chart for signal and condition confirmation - Drawing Objects.

Somehow it will not pass through this step

if(ToDay(Time[0]) == ToDay(DateTime.Now.AddDays(-1)))
                    {

Yet this exists in the chart. I am not sure why.

Hello,

I'm not able to replicate this error with this bit of code alone. While I dont know for sure without seeing the rest of the code you may consider adding the following as a check to ensure enough bars have been loaded before your processing begins.

// Checks to make sure we have at least 20 or more bars
     if (CurrentBar < 20)
          return;

Thanks! I just found the issue. I had some misunderstandings in the code where the code was called way before it should have. It called the code and then it realized that the lists that I use in the code are empty at this time. Soo that why I got the error.
