Alert Window

Description

As you know cAlgo & cTrader API doesn't has any type of built in alert window feature so I made this library for indicator developers who want to add an alert window on their indicators, Below is short tutorial of how to use this library.

Moved to: https://ctdn.com/algos/show/1692

New Version Changes:

  • The classic Windows UI changed to Metro
  • Alerts list control changed from ListView to DataGridView
  • Now you can limit the number of alerts
  • Top most window bug fixed

 

How to use Alert Window:
1. Use cAlgo reference manager and add "Alert.dll", "MetroFramework.dll", "MetroFramework.Design.dll", and "MetroFramework.Fonts.dll" DLL files to your indicator:

 

2. Set the indicator access right to " FullAccess":

    [Indicator(IsOverlay = true, TimeZone = TimeZones.UTC, AccessRights = AccessRights.FullAccess)]

3. Add the "AlertWindow"  and "System.Threading.Tasks" name spaces on top of your indicator code by adding:

using System.Threading.Tasks;
using AlertWindow;

4. Make an instance of "Alert" class:

private Alert _alarm;

protected override void Initialize()
{
	// The class constructor receives three parameters, Indicator name and symbol code
        // And Maximum number of alerts(it's optional and default value is 12)
	_alarm = new Alert("Your Indicator Name As String", Symbol.Code);
}

5. Now you can trigger an alert by calling "Trigger" method of "Alert" class, This method get two parameters:

// You should use C# Task for running the code asynchronously
// Signal Type can be buy and sell or long and short(string)
// Server.Time is the time of signal(event) occurrence.
Task showForm = Task.Factory.StartNew(() => { _alarm.Trigger(SignalType, Server.Time); });

Hello afhacker,

love your work. any chance of supplying a link to download the dll files listed above (ie  "Alert.dll", "MetroFramework.dll", "MetroFramework.Design.dll", and "MetroFramework.Fonts.dll" DLL ) that are needed for this indicator? Tried finding and downloading them myself but they end up being incorrect stating incorrect format etc. Appreciate any assistance to get these so I can add them to reference manager as stated above. Thanks

@newbee

You can get metro framework files from their site by installing it via "NuGet" or downloading it from their GitHub:

And for "Alert.dll" file:
