Access book from different bars in progress issue

[tkaboris]

Hi I have multi strategy.
in my primary bars in progress I reference book from another bars in progress and it’s not recognising.
is there a trick to reference Bools in another barsinpeofress?

Hello tkaboris,

Thanks for your post.

You should create the bool as a class level variable in your script.

Once the bool is created as a class-level variable, you could set the bool in say BarsInProgress 1 and then reference the bool in a different BarsInProgress in your script.

See this help guide page for details about working with Multi-Timeframe/Multi-Instrument NinjaScripts: https://ninjatrader.com/support/help...nstruments.htm

The Strategy Builder could be used to create a bool variable and then you could click the 'View code' button to see the generated syntax to create that bool in your script.

HI
So i have this issue with bools.
private bool 1buy;
private bool 2buy;


primary series {
if (Close[1] > Open[1]){
bool 1buy
}

if(1buy && 2buy)
enter long
}


secondary series {
if (Close[1] > Open[1])
bool 2buy
}

The problem is that 2buy reads from the primary series and not from secondary. when i print 2buy from secondary series it prints fine, but whenn i print 2buy in primary series its not picking up correctly

How can i work this out?

[tkaboris]

I have implemented T series
private Series<bool> mySecondaryDoubleSeries;
in dataloaded
mySecondaryDoubleSeries = new Series<bool>(BarsArray[2]);
when i print it from primary series it always evaluates to false even thought it should be true
Print("secondary series bool " + mySecondaryDoubleSeries[0]);

Am I doing it right?

Hello tkaboris,

This would only be true during BarsInProgress 0 if the value was set to true during the most recent bar update of BarsInProgress 0.

If you are synchronizing a custom series to an added data series, this will have a slot for every bar of the added series, not the primary series.

This means from the primary series, you would be referencing the most recently updated bar of the added series.

yes thats what i need, i need to access last condition on secondary series from primary.
So do i need T series for that? or no?

Hello tkaboris,

Thanks for your notes.

A custom Series<bool> could be used to check if BarsInProgress == 1 and set the Series<bool> to true or false.

You could then access the Series<bool> variable value in BarsInProgress 0. To understand how the script is behaving, prints should be added to the script that prints out the value of the custom Series<bool> variables in BarsInProgress 0 along with the Time. Prints should also be added in BarsInProgress 1 that prints out the Series<bool> value along with the Time. The prints could then be reviewed in the NinjaScript Output window to see how they are behaving.

Below is a link to a forum post that demonstrates how to use prints to understand behavior.
