Need help with Drawing text

[sisidemo]

I'm a beginner with ninjaTrader, and I am trying to draw text/verticalLine/... on the prev bar on the chart but I see notning

protectedoverridevoid OnBarUpdate()
{
if (CurrentBar == 1)
{
//DrawVerticalLine("tag1", 1, Color.Blue);
DrawText("tag1", "AAA", 1, High[1], Color.Black);
}
}

What am I doing wrong?
Thanks

Your condition CurrentBar == 1 is incorrect, since this paints only on bar #1.

Should read:

if (CurrentBar < 1)
return;
DrawText("tag1", "AAA", 1, High[1], Color.Black);

Thanks,

What is the correct syntax for drawing only on bar no.5?

if (CurrentBar < 5)
return;
DrawVerticalLine("tag1", 5, Color.Blue);

or is there another alternative?

Do you mean the 5th bar of the left of the chart or the 5 bars back from the current bar (which is the right most bar)?

If the latter, then your code is correct.

Thanks for the help,
Another question if I am in a for loop and I want to get the low value of index bar ago (low[index]), do I need every time in the loop do the check: if (CurrentBar < index) ?
Note: if I don't do the check I get Error to the Log.

What Is the correct syntax for this problem?

Example:
protectedoverridevoid OnBarUpdate()
{
for (int i = 25; i >= 0; i--)
{
if (CurrentBar < i)
continue;
Print(Low[i]);
}
}

[NinjaTrader_Dierk]

Your approach is fine. You also could do:
protectedoverridevoid OnBarUpdate()
{
if (CurrentBar < 25)
return;

for (int i = 25; i >= 0; i--)
{
Print(Low[i]);
}
}

Typical non-programmer question

Hello
As far as I understand the code :

if (CurrentBar < 1)
return;
DrawText("tag1", "AAA", 1, High[1], Color.Black);

should plot a triple A at the high of the lastbut one bar ,but I can't get no plot. What am I doing wrong?

That code works as expected. Please check your log tab for any other errors you may have in your indicator.

The code below for sure works as is.

protected override void OnBarUpdate()
{
if (CurrentBar < 1)
return;
DrawText("tag1", "AAA", 1, High[1], Color.Black);
}

Sorry but I did as described , compiles with no errors. Do I miss something like declaring a font or something like this ?

Works as expected

Hi jojojo,

It works as outlined. Attached is an indicator that demonstrates this. You can import it via the Control Center window, File > Utilities > Import NinjaScript.

Thanks Ray
But please consider this one .It's quite identical , that's what's driving me mad.

[NinjaTrader_Dierk]

That's pretty clear. You need to apply different (!) tag names for different drawing objects:

        protected override void OnBarUpdate()
        {
            if (CurrentBar < 1)
                return;
            DrawText("tag1", "AAA", 1, High[1], Color.Black);
            
            if (CurrentBar < 5)
                return;
            DrawVerticalLine("[SIZE=4][B][COLOR=Red]tag2[/COLOR][/B][/SIZE]", 5, Color.Blue);
        }

Ok you can call me goofy

Hello (still goofin around)
Another one : How can I plot this (example AAA)at the current price(at the right or left side) , so that the plot is moving up and down with the incoming ticks like a cursor?

How about:
DrawText("tag1", "AAA", 1, Close[0], Color.Black);
