Hello NISNOS69,

It is possible to send an Alert to the Alerts Log window with a sound with the Alert() method.

As far as flashing the screen, you could change the ChartControl.Properties.ChartBackground brush or you could open a new window.

Thankyou

Where abouts in the code would I insert it?

Thankyou

Also how would I specify it on a candle close?
Thankyou

Hello NISNOS69,

If you are wanting to call Alert() when a drawing tool method is called, you can call the Alert() method one line above or one line below the Draw method.

The script updates OnBarUpdate based on the Calculate setting. When set to OnBarClose, the logic is evaluated when the bar closes. When set to OnPriceChange or OnEachTick this will update before the bar closes. With these, require IsFirstTickOfBar to be true to trigger an action after a bar has closed.

I am also including a link to a support article with helpful resources on getting started with C# and NinjaScript.

thankyou -

Within this section of code?

{
            int num1 = this.LowestBarFromRange(startIndex, barIndex);
            this.bearishLows.Add(num1);
            this.validHighs.Add(startIndex);
            this.lowestLow = Low.GetValueAt(num1);
            if(this.DebugMode) Print(string.Format("Yes, validated high @{0}", startIndex));
            if(this.DebugMode) Print(string.Format("Resetting lowest low to {0}", this.lowestLow));
            int num2 = this.HighestBarFromRange(this.validLows.LastOrDefault<int>(), barIndex);
            int num3 = this.MarkSwingPeaks ? num2 : startIndex;
            this.swingHighs.Add(num3);
            if (this.ShowFractals)
                Draw.ArrowDown(this, "valid-high-" + barIndex.ToString(), true, CurrentBar - num3, High.GetValueAt(num3) + (15 * TickSize), this.ValidHighColor);
            if (!this.ShowSwings)
              return;​

I want the audio alert when the "arrow down" is drawn

thankyou in advance

Hello NISNOS69,

If the Draw.ArrowDown() call is the object in question, this is in a single statement block (no curly braces) and you would want to add curly braces for a multi-statement block and add the call to Alert() within the block.

if (this.ShowFractals)
{
Alert("myAlert", Priority.Low, "My Alert", NinjaTrader.Core.Globals.InstallDir+"\\sounds\\Alert1.wav", 10, Brushes.Black, Brushes.Yellow);
Draw.ArrowDown(this, "valid-high-" + barIndex.ToString(), true, CurrentBar - num3, High.GetValueAt(num3) + (15 * TickSize), this.ValidHighColor);​
}
