Line Alerts Absence driving me nuts

[e-man]

I created the following enumeration and placed in under the using declarations line

[FONT=Courier New][COLOR=black][SIZE=2]public enum[/SIZE][/COLOR][/FONT][FONT=Courier New][SIZE=2]SoundEffect[/SIZE][/FONT]
[SIZE=2][FONT=Courier New]{[/FONT][/SIZE]
[SIZE=2][FONT=Courier New]SoundFile1,[/FONT][/SIZE]
[SIZE=2][FONT=Courier New]SoundFile2[/FONT][/SIZE]
 
[SIZE=2][FONT=Courier New]}[/FONT][/SIZE]

i have a question about public enum's ... i have a picklist for MA-type (EMA, SMA, etc) and noticed that this code *only* compiles whenever it exists outside of namespace NinjaTrader.Indicator{} (just as MicroAl demonstrated)

the code that invokes MAType is declared as a private MAType in the variables section and then properly get/set in the properties section. and it's used inside of OnBarUpdate via a switch() statement to plot lines using the selected MAType.

when i copied my enum code from indicator#1 (which works great) to indicator#2, i started getting errors when i tried to compile it ... from what i can tell, the only way to complie it is to change the name of the enum (eg. from MAType to Indicator2MAType).

if i understand this correctly, it's b/c i have something "public" that is outside of the context of just this indicator. i'm not a c# expert, but something tells me this may not be the best-practice way to do an enum.

so two questions:
1) is there a way to isolate this code inside of the Indicator{} section so that i can just copy/paste the code over and over again (thinking the answer is no, and would love to know "why");
2) assuming there's a very good reason for a "no" answer to #1 above, where might one put a "global" type like this? can i make a file called MAType.cs and drop it somewhere and then invoke it from within indicator#1 and indicator#2

sorry for the super-geeky question here, but i would rather do it the right way than continue to hack things.

final comment ... i noticed that PriceType works pretty much like what i'm trying to do with MAType ... so another way of asking #2 would be: how do i make my MAType work like PriceType

thanks in advance for any ideas,

You should only create an enum outside as you have seen. You cannot create the same one twice in a second indicator since it will conflict with the first. If you just want this enum to be available across all your indicators, try putting it in UserDefinedMethods.cs. Regardless of where you put it, you just need it once and it should be available across all your other indicators.

brilliant! thanks so much!

Ok this is how I modified an indicator to select a sound file. I created the following enumeration and placed in under the using declarations line

+Using declarations
public enum SoundEffect
{
SoundFile1,
SoundFile2

}

in the OnBarUpdate Method I used a switch statement to select the sound file required eg

switch (MySoundType)

{

case SoundEffect.SoundFile1 :
(What you wish to do here eg Alert statement etc)
break;

case SoundEffect.SoundFile2 :
(What you wish to do here eg Alert statement etc)
break;
}

To create the drop down box in the region Properties section goes

[Description("Sound Required")]
[Category("Parameters")]
public SoundEffect MySoundType
{
get { return mySoundType; }
set { mySoundType = value; }
}

I am sure there are probably better ways to achieve this. I am not a professional programmer. In my modified indicator I have a selection of about 10 sound files, but it means 10 case statements that the computer
has to run through on every tick. However it does not seem to affect the running of the program.

Hope This Helps

Try defining a string variable for your different sound files, then put the switch where it is not acted upon at every tick:

if(CurrentBar < 1)
{
switch (MySoundType)
{
case SoundEffect.Ding:
SoundFile1 = "c:\\windows\\media\\ding.wav";sound file
break;
case SoundEffect.Chimes:also).
SoundFile1 = "c:\\windows\\media\\chimes.wav";
break;
case SoundEffect.DingDong:
SoundFile1 = "alert4.wav";
break;
}
return;
}

Now the only execution is when the choice is made and the string is applied to the variable SoundFile1. Now you do whatever you want with that variable later in your code.

Looks like a much better idea, Thanks for sharing.

Note for Moderators. For any discretionary day trader trading a fast moving index like the S&P, trying to take notice of tick readings, trin readings, put call ratio's, volume spikes, Moving averages, stochastics, RSI, elliot wave counts, pit audio, CNBC, BBC, ABC etc, Do you know how frustrating it is not to be able to quickly draw a support and resistance line (angled or straight) and put an alert on it?

I understand that this basic facility will not be available in Ninja 7. Ninja is a great product and clearly you people are excellent programmers, so I cannot see why almost every other package has this facility and yours does not. (I bet its another stupid patent problem)

You may want to consider a creating a variable lastTriggerTime and then do a check for Current Time > lastTriggerTime + 10 seconds. Then reset the lastTriggerTime to Current Time when conditions evaluate to true.

sorry, I am trying to figure this out too, could you please give me some sample coding to do that. I built a simple indicator, and added the alert, but I am kindof stumped on how to get it to delay after the first alert.

thanks

Solution for alerts for Lines

For the info of MicroAl and others interested in alerts from lines, there is now a solution, where you can just draw a line on a chart and have it trigger alerts.
It's a commercial product, at www.tradingcoders.com called Diagonal.

Cheers,

Line Alert

Thanks for info. Looks quite good.

Perhaps they should licence it to the Ninja developers who after at least two years have still not worked out a way to accomplish this

[saltminer]

it is now free

The product mentioned below, Diagonal, at www.tradingcoders.com is now a free give-away. (was $65)
Works on 6.5 and 7.

Been playing around with this works very well. Looks like you can have 2 horizontal lines or 2 sloping lines or a mixture of both. I also like the Alt and right click combination to draw the lines.

Are you connected with the company? If so thanks for donating to the community.

The only thing missing that I would like is a way to use my own sound alerts.

Edit looks like you can just replace the sound files in the documents folder
to whatever you want as long as you keep the names the same

I also think so.thanks
