Multi instrument

[alexstox]

Hello. I want general stock enter market after some conditions of secondary instrument.
So, I add new stock in strategy from sample like this

 
protected override void Initialize()
        {
			...................................
			
			// Add own index to strategy
			Add("MSFT", PeriodType.Day, 1);
			
			CalculateOnBarClose = true;
        }

Than I'd like to enter long if secondary stock (MSFT) close more than previous 20 closes. How to do this?

protected override void OnBarUpdate()
        {
            
			// Condition for long
			if (
				Close(BarsArray[1])[0]>=MAX(BarsArray[1],20)&& 
.................................................................................................................................

Hello,

You'll want to use Closes to get the correct closing price if you're outside of the secondary series

If you haven't done so already I'd suggest reading this article: http://www.ninjatrader.com/support/h...nstruments.htm

if( Closes[1][0] >= MAX(BarsArray[1],20) )
{
  //enter long here, you'll want to pass the correct BarsInProgress overload
}

Let me know if I can further assist.

Check for instrument name or class in script

Hello. I use strategy to backtest some instruments. What if I need to check in script name and class of instrument?
For example, I run Strategy Analyzer on forex $EURUSD, $USDCAD, stock MSFT, futures CL ##-##. So, how and when to check (in Initialize() or in OnBarUpdate())? Because Instrument can't be accessed within the Initialize() method.

Hello alexstox,

Thank you for your post.

You can do this at the beginning of the OnBarUpdate() method using the Instrument.FullName: http://www.ninjatrader.com/support/h...t_fullname.htm

Well, I thought it's too brutal. Maybe Instrument can be used in OnStartUp()?

Week bar value in Day bar

One more question. I add weekly chart to strategy. So, there are MSFT daily and MSFT weekly. I check for week close up or down. Problem is that this up or down true only on day which week closes.

For example, week closed on 11JUL2014 and condition is true only on 11JUL2014, next only on 18JUL2014, but not on 14,15,16,17JUL2014.

What should I do to see last week close in after-week-close days?

Hello alexstox,

Thank you for your response.

Bars would not be loaded OnStartUp() either. And for the Weekly close you need to make sure you are accessing the Closes[1][0] to ensure you are accessing the weekly close. If this is not the case can you provide the code that is not working?

1) I asked about OnStartUp() to check for Instrument.FullName. Will it work there?
2) I use indicator with BoolSeries UP and DOWN (week close up or week close down). So, in strategy script OnBarUpdate() condition UP[0] is true only on week's end. That;s why days between two weeks' ends are false. How to avoid this?

[NinjaTrader_PatrickH]

Hello alexstox,

The Instrument.FullName will work in the OnStartUp() method. The value of the BoolSeries should be the previous week's end until the current week does in fact close, so your understanding of the issue is incorrect. The value is only false if the previous is down.

If you do not believe this is the case, please provide the full code used for the BoolSeries.

[alexstox]

Please look at attached Output. So, as you see there on week's end day (date at which week closes) everything is OK. But days betweens weeks' ends are contrary.

protected override void OnBarUpdate()
		{
			if (CurrentBars[0] <= BarsRequired || CurrentBars[1] <= BarsRequired /*|| CurrentBars[2] <= 20*/)
				return;
	if (BarsInProgress==1) //start BarsInProgress
{
if (blablabla)
	{
	WeekHigh=High[0];
	WeekLow=Low[0];
	momDW=0;
	momUP=1;
               }
		
else if ( blablabla)
	{
	WeekLow=Low[0];
	WeekHigh=High[0];
	momDW=1;
	momUP=0;
	}
				
if(momUP==1) 
{
dOWNweek.Set(false);
uPweek.Set(true);
}
					
else if(momDW==1) 
{
dOWNweek.Set(true);
uPweek.Set(false);
}

So, I think this because of BarsInProgress==1 is absent in between weeks's ends days. Indicator works with weekly bars. I use this indicator in strategy with daily bars.

Hello alexstox,

Thank you for your response.

Can you provide a full test script attached to your response in it's .cs file format? Are you using CalculatOnBarClose = False?

Hello alexstox,

Thank you for your response.

Can you provide a full test script attached to your response in it's .cs file format? Are you using CalculatOnBarClose = False?

I can sent it to you via mail. I used COBC=False and True. Nothing changed.
I used script on EOD data in Strategy Analyzer

Hello alexstox,

Thank you for sending in the file.

Are you applying the same indicator to another bar series? How are you getting the days between the week closes?

[alexstox]

Hello alexstox,

Thank you for sending in the file.

In strategy script I add
Add(MyInstrum1,PeriodType.Week,1);
Than in OnBarUpdate() tried to use as condition
CloseWeek(MyInstrum1).UPweek[0]
but you know the result.

You know what is interesting? After week Up on following days Upweek==false, DOWNweek==true!!!! and vice versa after week DOWN on following days DOWNweek==false, UPweek==true!!! You can see this in Output, that I attached earlier.

So, can you help me please?
