index was out of bounds

[birdog]

Hi:

I am adding a 3rd index on the bararray (I already have 2 that works perfectly). When I add the 3rd I get this error: index was out of bounds of the array?

What would be causing it?

Depends on how you are adding it, and how you are referencing it. It is hard to say without seeing some code.

Hello birdog,

Thank you for your post.

Have you added the third object in the code? (i.e Add())

What is the exact code used with the BarsArray? Please detail in your response.

I look forward to your response.

Hey Koganam:

Ok...sure...here is the initialize (I have the 60 Minute disabled just so you know...it works fine with the Day and Week on but when I add the 4 hour I get a the error):

// Index 0 is the primary bars selected upon startup-Index 1 is Daily-Index 2 is Weekly-
            // Index 3 is 60 Minute (hourly)-Index 4 is 240 Minute (4 hour).
            // Add 1 Day (Daily) Bars object to the strategy
            Add(PeriodType.Day, 1);
            
            // Add 1 Week (Weekly) Bars object to the strategy
            Add(PeriodType.Week, 1);
            
            // Add 60 Minute (aka hourly)Bars object to the strategy
            //Add(PeriodType.Minute, 60);
            
            // Add 240 Minute (aka 4 hour) Bars Bars object to the strategy
            Add(PeriodType.Minute, 240);

Here is onbarupdate:

if (CrossAbove(SMA(Fast), SMA(Slow), 1)
&& x < myTradeCounter
&& (EMA(BarsArray[1], 1)[0] > EMA(BarsArray[1], 3)[0]
&& EMA(BarsArray[2], 1)[0] > EMA(BarsArray[2], 3)[0]
//&& EMA(BarsArray[3], 1)[0] > EMA(BarsArray[3], 3)[0]
&& EMA(BarsArray[4], 1)[0] > EMA(BarsArray[4], 3)[0]))

Hello birdog,

Thank you for your response.

You currently only have 3 PeriodTypes added in the code, yet you are referencing BarsArray[4].

You need to change that to 3 rather 4, as you have commented out the other PeriodTypes in Initialize() and the BarsArray[3] in the OnBarUpdate().

For example:

if (CrossAbove(SMA(Fast), SMA(Slow), 1)
&& x < myTradeCounter
&& (EMA(BarsArray[1], 1)[0] > EMA(BarsArray[1], 3)[0] 
&& EMA(BarsArray[2], 1)[0] > EMA(BarsArray[2], 3)[0]
//&& EMA(BarsArray[3], 1)[0] > EMA(BarsArray[3], 3)[0]
&& EMA(BarsArray[3], 1)[0] > EMA(BarsArray[3], 3)[0]))

Please let me know if you have any questions.
