How to refer to a specefic bar

[Ad_Trader]

I am trying to DrawText on a specific bar but how do I refer to that bar, I have tried many things but with no success

DrawText("7",true,"T", 2    ,High[2],0,Color.Blue,new Font("Arial", 8),StringAlignment.Center,Color.Black,Color.Yellow,10 );

0 and 1 in the barsAgo parameter are drawing but 2 and above (3,4,....)aren't drawing, please tell me what am I missing

Hello,

This line of code is correct however you will need to add an additional check to ensure enough bars have been loaded before hand. If you go to tools -> output window you would see an error message

This can be avoided with a current bar check at the start of your OnBarUpdate()

example
if(CurrentBar < 2)
return;

Let me know if I can further assist.

Thank you for the very fast reply,

when I enter the if statement it worked fine for 2 bars ago, and then I modified it to

if  (CurrentBar < 200) return;

now I can refer from 0 to 200 bars ago, what is the secret of the CurrentBar < number since the chart already having 247 bars as per the Count value

You are correct in noticing Count will be the total number of bars on the chart.

However when an indicator is run it starts processing on bar 0 and will evaluate from left to right. The error is then being generated because it's trying to place a drawing object where there is no data at the very start

CurrentBar allows you to see the current bar that's being processed where as Count give total bars on the chart

Let me know if I can further assist.
