Two Simultaneous Sound Alerts

[laocoon]

Hello

My custom strategy has two different signals that usually don't appear at the same time but occasionally this is the case. I use a PlaySound function with a different sound for every signal. This works fine most of the time but when both signals appear at the exact same time, no sound is played at all.

I was wondering what the simplest way would be to resolve this.

Thanks

laocoon, I would then resort to using the Alerts() method as it would offer assigning different priorities and rearm seconds so they should trigger even if overlapping technically.

Thanks for the tip Bertrand. I did the modifications and I'm currently testing the new version.

Hello Bertrand

I did as you suggested, but for some reason it still doesn't work (when I get 2 simultaneous signals, there's no sound at all). Here's the code:

Alert("Alert1", NinjaTrader.Cbi.Priority.High, "Long1", "Long1.wav", 1, Color.Black, Color.Yellow);

Alert("Alert2", NinjaTrader.Cbi.Priority.Medium, "Long2", "Long2.wav", 5, Color.Black, Color.Yellow);

Any tips on how to solve this would be much appreciated.

Thanks

laocoon, so each alert on his own would trigger and work ok? Then they just overlap, an idea here would be just adding some ms delay (silence) into the second sound file used, or more complicated use a timer event to trigger the second alert a tad bit later...

You can use my SpeakTextHelper functions in Zweistein.Library also for playing audio files

I am using a threadpool queue to ensure that all incoming sound are played consecutivly and without overlap.


The library is a by-product of the COTReport Indicator.

Bertrand,

Thanks for your tip. Yes, each alert on its own triggers and works ok.
I'll try the delay idea but I'm a bit frustrated because I thought that the Priority setting would take care of the problem.

Thanks

Thanks Zweistein, I'll look into it.

@Zweistein: am I right in assuming that in order to get access to the library you're mentioning I'd have to purchase the COTReport Indicator?

@ Bertrand: the delay (silence) for the second sound file or even the timer won't solve the problem because I'm using a few different signals that are independent from each other but that can occasionally be triggered at the exact same time in a random combination, ie, Signal 1 can be triggered in conjunction with Signal 3, but the next time it could be Signal 1 combined with Signal 2 etc. Your solution would only work if it was always the SAME pair (combination) of Signals that are triggered together. Isn't there another, straightforward way to solve this issue? (What are the Priority settings for? I thought they were designed to do just that.)

Thanks

[zweistein]

Yes, and cotreport will be a one off payment only.

Then you can use Zweistein.Library with
Zweistein.Speechhelpers.SpeakText(string s);
Zweistein,Speechhelpers.SoundFilePlay(string relativepath);

Hello,

Unfortunately there is no straight forward way to solve this and it is a current limitation and needs to be programmed for. The priority action just assigned a color in the Alert window.

You would need to use a Timer or introduce time into each sound file. You can also do this with DateTime if the indicator is set to CalculateOnBarClose.

Let me know if I can be of further assistance.
