Hello All,

I would like the following condition to generate an alert on the first bar only. Unfortunately, my limited knowledge has a dot at each bar until the condition changes.

if EMA (8) [0] > SMA (20) [0] && SuperTrend.UpTrend [0] == true
{
DrawDot ("Dot", true, 0, High [0], Color.Green)
}

Thanks in advance.

use an extra flag (bool)
when the condition is met, you put the flag
when the condition stops, you remove the flag
if the flag is put, the signal can not be generated

good luck !

Thanks for the reply.
I don't have a clue about flag (bool) can you point in a direction to learn.

roughly like this :

 

Code

if (EMA (8) [0] > SMA (20) [0] && SuperTrend.UpTrend [0] == true && !fired) { DrawDot ("Dot", true, 0, High [0], Color.Green); fired = true; } if (EMA (8) [0] < SMA (20) [0] || SuperTrend.UpTrend [0] == flase) { fired = false; }
