Call Reload NinjaScript (F5) as a function.

I need to call reload ninjascript AKA default "F5". Ninjatrader does not support that automatically. I was wondering if anyone had made this code. Please share. Thank you.

Probably closest you will get is using SendKey to send an F5 keyboard press.

Yes u right, but it is working only for the ACTIVE window. Does not work for multi-workspaces. If anyone found a solution besides the SendKey. Please answer. Thx Mike. Thx Guys. Great FORUM!!!.

Yes, you can use the HistoricalDataManager to load dataseries.

Heres an example of how to load the first dataseries of the currentchart this specific example must be in an indicator because of how it obtains the bar-dataseries to reload, but you can use the datamanager from anywhere and use any barseries).

Since the method gets an ArrayList you can ofcourse reload multiple series with the same call (just add each to the arraylist - for instance loop through the BarsArray of the ChartControl and add each to reload all dataseries of the current chart (this is what "F5" does)

Code

Bars b = this.ChartControl.BarsArray[0];		
ArrayList br = new ArrayList();	
DateTime f =b.From;
DateTime t =b.To;
if (b.Count>0 && b.GetTime(0)<b.From) f=b.GetTime(0).Date;
if (b.Count>0 && b.GetTime(b.Count-1)>b.To)t=b.GetTime(b.Count-1).Date;			
HistoricalDataManager.BarsRequested barsToLoad = new HistoricalDataManager.BarsRequested(b.Instrument, b.Period, f,t) {
   Session = b.Session
};			
br.Add(barsToLoad);
new HistoricalDataManager.RequestBarsFromProvider(null).DoReloadFromProvider(br);

ChartControl.HotKey((Keys) HotKeyManager.ChartHotKeys.ReloadNinjaScript);

has anyone found a way to reload NinjaScript without using a send key in NT8?

I've run into issues where the chart window loses focus and it sends the F5 key press to another window

I needed this as well, and found this undocumented way...

ChartControl.OnReloadNinjaScriptHotKey(this, new System.Windows.Input.KeyEventArgs(Keyboard.PrimaryDevice, PresentationSource.FromVisual(chartControl), 0, Key.F5));

What about calling the function ForceRefresh()? You can read about it on the NinjaTrader website

ForceRefresh only triggers the visuals to re-render, it does not reload the scripts/indicators/strategies running the chart.
