any pause command

[toyogo00]

Hi,

I am trying to have to play two audio files based on certain condition. However, only 2nd file will be played as it ignored the 1st file. Thus I'm thinking if there is a pause command in between the two statements, it should be ok.

if (condition1) Alert("audio1.wav");
if (condition2) {
pause(<5 seconds>); // assume the audio1.wav is about 5 seconds
Alert("audit2.wav");
}

OR there is a better way!

You NEVER should pause your NinjaScript, since this could lock up NT. You could try playing around with a timer based approach like here: http://www.ninjatrader-support.com/v...ead.php?t=5965

Hi,

The example provided is too complicated which I don't think it applied to my case. Anyhow, I only want a simple timer. I used to use the loop command such as:

for (i=0 to 1000) i--; this will provide a simple delay for few seconds. However, as this method is depending on the CPU speed, it is not accurate at all.

There are programming languages provide simple command like delay(5) to set timer for 5 seconds. I'm looking for such command in NT

Please see my post below: you NEVER should code a "busy wait" but code a timer based approach as in link I provided. If it's too complex, then I suggest accepting the limitation you experienced in your initial post.

Don't know if this will work for you, and don't know if it would cause a problem in NT (maybe Dierk could comment).

System.Threading.Thread.Sleep(3)

This example would insert a 3 millisecond delay.

This is exactly what you should NOT do, since it locks up NT.

Does this mean that all NinjaScripts are single threaded? For example, if I have a global variable which I change in one call (say OnOrderUpdate) there is no danger of effecting another thread running somewhere else (say in OnBarUpdate) ?

As of now that is correct. But don't rely on that, but apply .NET locking, since this might change with NT7.
