Prints not showing

[itrader46]

Hello
I have the code below, but the prints for the prints for the second series (5 min) are not showing in the output window and I don't understand why?

else if (State == State.Configure)                
                {
                    AddDataSeries(Data.BarsPeriodType.Tick, 1);
                    AddDataSeries(Data.BarsPeriodType.Minute, 5);                   
            }
...
protected override void OnBarUpdate()
        {
            // Make sure this strategy does not execute against historical data
            if (State == State.Historical)
                return;            

            if (!strategyStart)
            {
                if(PrintOutput)
                {
                    if (BarsInProgress == 0)
                    Print ("Strategy start 1 min bar: " + CurrentBar + " - " + Time[0]);

                    if (BarsInProgress == 2)
                    Print ("Strategy start 5 min bar: " + CurrentBar + " - " + Time[0]);                           
                }
                strategyStart = true;
            }

Hello itrader4,

Thank you for the post.

Did you happen to remove/re apply the script after adding the secondary data?

I otherwise don't see the problem here specifically. you may try a print like the following to better understand if the series is being called at all:

protected override void OnBarUpdate()
        {
[B]Print(BarsInProgress + " " + Time[0]);[/B]
            // Make sure this strategy does not execute against historical data
            if (State == State.Historical)
                return;            

            if (!strategyStart)
            {
                if(PrintOutput)
                {
                    if (BarsInProgress == 0)
                    Print ("Strategy start 1 min bar: " + CurrentBar + " - " + Time[0]);

                    if (BarsInProgress == 2)
                    Print ("Strategy start 5 min bar: " + CurrentBar + " - " + Time[0]);                          
                }
                strategyStart = true;
            }

Edit: On a second look I see you have strategyStart = true;, if BIP 0 or 1 called OnBarUpdate and set that to true you would not see the print when BIP 2 eventually calls OBU. I would suggest removing your condition here and just print the value to confirm that is working first.


I look forward to being of further assistance.

That's the result: series 2 is called, but it's not printing and I always remove and reapply the script after making changes

Hello itrader46 ,

Thanks for testing that.

it looks like this relates to your conditions, you would need to reform the conditions you have. The series is being called so the problem lies later in your code.

Lets assume BIP 0 called OBU:

0 18/11/2019 05:15:00

1. Your logic is run and the print is seen:
   • Strategy start 1 min bar: 1753 - 18/11/2019 05:15:00
2. You set strategyStart = true;
3. You surround the prints with a condition if (!strategyStart) if the variable is not true, but you set it to true.
4. Now the prints should no longer work for the other series based on what you have programmed.

It seems to be working as it was designed currently.

But I thought that strategyStart bool doesn't become true until after it processed series 2 bar printing?

 if (!strategyStart)            
{                
   if(PrintOutput)                
   {                    
      if (BarsInProgress == 0)                    
      Print ("Strategy start 1 min bar: " + CurrentBar + " - " + Time[0]);                      
      if (BarsInProgress == 2)                    
      Print ("Strategy start 5 min bar: " + CurrentBar + " - " + Time[0]);                                          
   }                
   strategyStart = true;            
}

Hello itrader46 ,

Thanks for the reply.

Not in this case based on how you formed the logic, pay specific attention to the placement of the variable and your curly braces:

if (!strategyStart)
{
[B] if (PrintOutput)
    {[/B]
        if (BarsInProgress == 0)
            Print("Strategy start 1 min bar: " + CurrentBar + " - " + Time[0]);
        if (BarsInProgress == 2)
            Print("Strategy start 5 min bar: " + CurrentBar + " - " + Time[0]);
[B]   }
    strategyStart = true;[/B]
}

The BarsInProgress checks you have will not all happen in the same OnBarUpdate call, you would see 3 separate OnBarUpdates to see this logic executed fully. As you have it now if this happens one time it will set it to true preventing it going forward unless strategyStart becomes false again at some point. There is nothing in this condition to make the strategyStart set true only for BIP2.

Did you intend to do:

if (!strategyStart)
{
    if (PrintOutput)
    {
        if (BarsInProgress == 0)
            Print("Strategy start 1 min bar: " + CurrentBar + " - " + Time[0]);
[B] if (BarsInProgress == 2)
        {
            Print("Strategy start 5 min bar: " + CurrentBar + " - " + Time[0]);
            strategyStart = true;
        }[/B]
    }
}

This would only be set once the BIP 2 has been called once.
