Hi,

I am new to coding in NinjaTrader. I have done some coding in EasyLanguage, AmiBroker and Python, but I'm just a trial and error guy, not a 'proper' coder.

As a first foray into Ninja, I am trying to draw a dot beneath bars based on a condition being true.

if I make my condition as simple as possible, like this:

 

Code

if (Close[0] < Open[0])

-- the dots display correctly.

But, if I try to refer to previous bars, like this:

 

Code

if (Close[0] < Open[1])

-- the code does not work. So, I assume it is the condition itself which I am getting wrong.

Can anybody explain why this change would stop the code working, and how I would correctly refer to previous bars?

Any help appreciated.

Here's the rest of the code.

 

Code

protected override void OnBarUpdate() { { if (Close[0] < Open[0]) //if (Close[1] > Open[1]) //if(Close[1] < Close[0] && Close[1] < Close[2]) { myBarCloses=1; } else { myBarCloses=0; } if (myBarCloses==1) { DrawDot(CurrentBar.ToString() +"BarCloseDot",true, 0, Low[0]*0.997, Color.Magenta); } } }

In case anybody else has a need for this information, it requires a check for enough bars in the data series you are accessing.

I don't know whether posting external links is permitted, so I'll assume it is not. A Google search should find the info.

I had to amend the code as below.

 

Code

protected override void OnBarUpdate() { if (CurrentBar < 1) return; if (Close[0] < Open[1]) // etc }

What do you mean "it does not work"? What exactly do you do and then what happens?
Is this for a strategy or an indicator?
Have you checked the "Log" tab in the "Control Center" for any runtime error messages? If so what do they say?
