Any Ninjascript for Chart marker following Alert? / Same alert for multiple markets.

[dmackay41]

I am inquiring as to whether there is any Ninjascript that can plot a Chart Marker, namely an Arrow Up following an alert to identify a Bullish candle and vice versa for a Bearish one.. rather than the pop up dialog box in the Alerts Actions section.

Also is there any process for setting the same Alert to multiple markets as opposed to setting the Alerts box to every chart?

Thank you

Hello dmackay41,

Thanks for your post.

Alert() would be used to create alerts when a certain condition becomes true.

Draw.ArrowUp() would be used to draw an up arrow on the chart whenever a certain condition becomes true. Similarly, Draw.ArrowDown() would be used to draw a down arrow on the chart. For example, something you could do is check if there is an up bar (Close[0] > Open[0]) and then call Draw.ArrowUp() to draw an up arrow. Note that to have that up arrow draw on each bar the condition is true instead of just the most recent bar, you would need to add CurrentBar to the tag parameter.

For example, the code below calls an alert and draws an up arrow 5 ticks above the High price when we have an up bar.

if (Close[0] > Open[0])
{
     Alert("myAlert", Priority.High, "Up Bar", NinjaTrader.Core.Globals.InstallDir+@"\sounds\Alert1.wav", 10, Brushes.Black, Brushes.Yellow);
    Draw.ArrowUp(this, "tag1" + CurrentBar, true, 0, High[0] + 5 * TickSize, Brushes.Green);
}

It would be possible to set Alerts for multiple instruments in a NinjaScript. To do so, you would need to add additional data series to your script using AddDataSeries(). Then, you would reference the BarsInProgress value of the added series and call Alert(). This will produce an alert when a certain condition becomes true on the specified added series.
