Has anyone managed to trigger a daily reload call using script only? i.e. set a time early in the morning refresh data once and continue. So a reload once per session at a given time.

This answer from the previous page seems promising .. if it can process SendKey for F5 can you also use this approach to reload data with the multi-key sequence CTRL-SHIFT-R to reload the data?

 

Code

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));

Earlier posts in this thread speak to a NT7 approach that might still work.

The only other way I have seen mentioned is using an external test or automation tool (one being the hacky AutoHotKey) and using that to SendKey F5 to reload Ninjascript and SendKey CTRL-SHIFT-R to reload the data.

Thanks yea either this through key or programmatic ReloadAllHistoricalData(). Main thinking was around making sure you only do it once per day at a specific time, lets say before you started the strategy time window for executions. Working on an approach to save last reload day to a file, so new instance after reload would know it has already reloaded for the day, otherwise the variable state would be nuked with the reload and you could be caught in a tailspin of reloading action (uncool lol).

Doing it through text file simply to serve as reload memory seems to work well. Will continue to check and finetune.

Why not through that into a simple AddOn that runs once in the background every day... set and forget..

Want your NinjaTrader indicator created, free? Agreed! The ReloadAllHistoricalData solution is NOT an F5 Reload NinjaScript Equivalent! (unless you want Every Chart to Refresh Data w/one command, kinda like requested) Regretfully for years an F5 code equivalent has been asked for.. to no avail! So …
