V count indicator

[luvette]

I'm trying to use a V countdown indicator in the non price study and would like it to be centered in the lower pane instead of the diplay at top, can any one suggest changes I need to do to accomplish this task

I'm not sure this is what you are looking for but try this.

thanx Wayne, thats perfect

Wayne, I'm trying to add alert to play sound when counter hits 10 for the same script. Which part of this script can I use to accomplish the alert

thanx Alex for your help got the alert working, I'm also trying to get the counter to flash on / off once alert is set and could use help on how to accomplish that as well

You are welcome.
As to flashing on and off the counter try searching the forum as I believe JasonK already posted a complete example that illustrates how to accomplish this and that you can adapt to your script

Alex, I found that changing the color when alert goes off will be equally helpful. I add the following to change color but with no success, do I need to add another line of code, obviously the script isn't correct.

Hi Peter,

I am sure that Alex can solve this issue but I see a few errors in your code that if fixed can help. The syntax of the drawTextRelative statement in your code does not appear to be correct. The subtax is supposed to be:

drawTextRelative( barIndex, yValue, text, fgColor, bgColor, Flags, fontName, fontSize [, tagID] [, cx] [, cy] )

In your code your first parameter, the bar index, is 2. So you are drawing two bars ahead (in the future) of the current bar. I am not sure if that is what you want. If you are looking to draw 2 bars back of the current bar than the number should be -2.

Nest parameter you have is close(). That should be close(0) for the current bar close or close of some n bars back; i.e. close (-n).

Your next parameter is z. You define z as a number but the drawTextRelative requires that the third parameter is to be text. Perhaps you want to convert z to text; for example use z.toString() or simply "z" in this position.

I hope this helps a little.
Regards,
Jane

thanx, the script works well but I'm trying to change color of counter when it is less then set value for alert and not sure how to get that done.

Hi Peter,

Great! Please note that you don't need the if(z > 13) in the first draw stament.

Jane

Jane without it the counter doesn't change color, atleast on my end... but none the less it works. This one plots in non price study

Hi Peter,

Just a slight correction to the last condition of both scripts. Please see below:
