ReloadNinjaScript()

[rcsingleton]

Hello.

I've got a request for a new NT function. I'd like to be able to do the following :

if (FirstTickofBar)
{
ReloadNinjaScript()
}

It would be great to have an automated way of reloading the active Ninjascript running on the chart.

Regards,
R. C.

Thanks for the suggestion.

Hello.

Not sure if you have the ReloadNinjaScript() function on your 'to do' list for NT 7, but either way, that's a long way off.

So, I would like to create a 'user defined function' that contains the code under 'F5 - Reload NinjaScript'.

Then I could assign that code to a function called ReloadNinjaScript().

And then use that function in an indicator.

Could you let me see the code under 'F5 - Reload NinjaScript' ?

Unfortunately that is not supported.

I would also like to suggest an improvement for NT7

As a real time chart may have several ninjascripts running. when you do a reload you lose all the calculated data for the chart display.

Under inidicators I would like the ability to individually reload any indicator.
ie add a button RELOAD alongside ADD & REMOVE so you dont have to relaod every indicator and lose data.

Thank you

Thank you for voicing your thoughts. I have forwarded them to development.

You could try this.

using System.Windows.Forms;
.
.
.

if (FirstTickOfBar)
{
SendKeys.Send("{F5}");
}

Thanks guys... I've been thinking about something similar and didn't know F5 would reinitialize the code ;-) -- thanks for the tip...

Hello.

Is there any way to do the following :

Every 120 seconds
{
SendKeys.Send("{F5}");
}

How do I set up a timer here to hit F5 every 120 seconds?

Thanks

rcsingleton,

Please see here for creating your own custom events: http://www.ninjatrader-support2.com/vb/showthread.php?t=5965
