NinjaScript Buggy and Inacurate. Please Help !!!

[Obi]

Hello,

I created a test indicator (accepting the default values of the wizard just to have a bare minimum indicator, in order to debug the odd behavior)

The resulting created indicator code and the test code:

protected override void OnBarUpdate()
{
Print("");

for (int idx =0; idx < 20; idx++)
{
Print("Value before : " + Close[idx]);
}
Print("");

// Use this method for calculating your indicator values. Assign a value to each
// plot below by replacing 'Close[0]' with your own formula.
Plot0.Set(Close[0]);
}

After loading this to a "3Minutes YM Chart, Connected to simulator", I get the following odd result:

Value before : 10594


1. The print shows only one value (the above value)
2. This value is not even the last value showing on the chart ( 10729 is the last value).
3. 10 minutes, 30 minutes and An hour later, I still get the same single value.

I changed the code to the following:

protected override void OnBarUpdate()
{
Print("Value After : " + Close[0]);
Print("Value After 2: " + Close[1]);
Print("Value After 3: " + Close[2]);
Print("");

for (int idx =0; idx < 20; idx++)
{
Print("Value before : " + Close[idx]);
}
Print("");

// Use this method for calculating your indicator values. Assign a value to each
// plot below by replacing 'Close[0]' with your own formula.
Plot0.Set(Close[0]);
}

The result (some 10 minutes later):

Value After : 10594


That's it!??? No need to tell you that this is very odd and extremely frustrating.

I desperately need your help and solution to this bug as all my work is currently suspended until this is resolved.

First, you need to convert the Close[] to a string before you print it out

Close[0].ToString();

Second, you should have the following statement before your for loop.

if(CurrentBar < 20)
    return;

The reason for this is you don't want to cause an exception by trying to access data that doesn't yet exist on the chart.

hope this helps

Hi Obi, I already responded to your email sent to our support inbox.

Thanks for your input mrlogik.

Hi NinjaTrader_Bertrand and Mr.Logik,

The following still give the same result as explained earlier:

protected override void OnBarUpdate()
{
Print("Value After : " + Close[0].ToString());
Print("Value After 2: " + Close[1].ToString());
Print("Value After 3: " + Close[2].ToString());
Print("");

// for (int idx =0; idx < 20; idx++)
// {
// Print("Value before : " + Close[idx]);
// }
// Print("");

// Use this method for calculating your indicator values. Assign a value to each
// plot below by replacing 'Close[0]' with your own formula.
Plot0.Set(Close[0]);
}

Result:

Value After : 10594

As you can see, hours after I reported the issue, I'm still getting the same single value.

Can you please have a look at this. It's blocking everything.

I did not see that you added this to your code:

if(CurrentBar < 20)
return;
