Sending Emails
Sending emails from within the platform allows the user to receive trade alerts, risk warnings and status messages even when not sitting in front of the screen, which helps react faster to market events and monitor strategies with less time spent watching charts.
To send emails from code, the user must first configure an email (SMTP) account in TWM and then call SendMail in scripts.
Configure SMTP in Options
1. Open TWM and click on “Tools” (1) and then options (2)
2. Click on “Email” to access the email settings
3. In the Email panel, fill in:
- Host: SMTP server of the email provider.
- Port: SMTP submission port, usually 587 (TLS/STARTTLS) or 465 (SSL).
- Username: Full email address or login name used for SMTP authentication.
- Password: Account password or app‑specific password, depending on provider security.
- Test email: Any destination address for a quick test.
4. Click Send (4) to verify the configuration; only proceed if the test email arrives successfully.
Provider examples
Email providers uses their own settings, always verify the details with the mail provider, here are some examples:
- Microsoft 365 / Outlook
Host: smtp.office365.com, Port: 587 (TLS), Username: user@yourdomain.com
- Gmail / Google Workspace
Host: smtp.gmail.com, Port: 587 (TLS) or 465 (SSL), Username: full Gmail or Workspace address
When 2‑Step Verification is enabled, the user must create an app password in the Google Account and use that as the SMTP password.
- GoDaddy mail
Workspace Email commonly uses smtpout.secureserver.net; Microsoft 365 plans use smtp.office365.com
Port: 465 or 587, Username: full mailbox address, for example alerts@yourdomain.com
- Fastmail
Host: smtp.fastmail.com, Port: 465 (SSL) or 587 (TLS), Username: user@fastmail.com
Sending emails from code
Once an SMTP account is configured and the test email works, the user can send emails from scripts with:
SendMail("receiver@address.com", "subject", "body");
Debug Window
Use the clear debug command to clear the debug window located in New -> Debug at any time.
Autoscale
Both strategy and indicator plots can be assigned to an autoscale parameter globaly or individually. Autoscale allows the chart to zoom in/out the plot object automatically when the A button at the top of the Y-Axis of the chart is enabled.
public override void OnStateChanged()
{
if (State == State.SetDefaults)
{
// Will set autoscale for the entire indicator
IsAutoscale = true;
}
}
private void AddIndicators()
{
_maSlow = EMA(Low, PeriodSlow);
// Will set autoscale only for this specific plot
_maSlow.Plots[0].IsAutoscale = false;
}
Drawing Arrows
You can draw arrows pointing in 4 directions. ArrowConnector property defines the point of the arrow that should be attached to the Y property which is in the example below is defined by High and Low prices of the current bar.
The tag property should be unique for each drawing object. If you place an object with the same tag, the old object with the same tag will be overwritten.
if (_enterShort)
Draw.Arrow(this, ArrowDirection.Down, CurrentBar + "Short", 0, High[0], ArrowConnector.End, Brushes.Red);
if (_enterLong)
Draw.Arrow(this, ArrowDirection.Up, CurrentBar + "Long", 0, Low[0], ArrowConnector.End, Brushes.Green);
public enum ArrowDirection
{
Left,
Down,
Right,
Up
}
public enum ArrowConnector
{
Start,
End
}
Coloring Bars
You can conditionally color any bar from code.
if (High[0] > High[1] && Low[0] < Low[1])
{
BarBrush = Brushes.Blue;
}
Adding Custom UI
It is possible for users to add custom UI to chart trader panel to be used from within the strategy/indicator code.
private Button _button;
private Button _button2;
public override void OnStateChanged()
{
if (State == State.SetDefaults)
{
// You might want to complete this line:
// e.g., Name = "YourScriptName";
}
else if (State == State.Configured)
{
Chart.ChartControl.Dispatcher.Invoke(() =>
{
var grid = new Grid();
grid.ColumnDefinitions.Add(new ColumnDefinition() { Width = new GridLength(1, GridUnitType.Star) });
grid.ColumnDefinitions.Add(new ColumnDefinition() { Width = new GridLength(1, GridUnitType.Star) });
_button = new Button
{
Content = "Test2",
Height = 24,
Margin = new Thickness(2)
};
_button.Click += Button_Click;
grid.Children.Add(_button);
Grid.SetColumn(_button, 0);
_button2 = new Button
{
Content = "Test3",
Height = 24,
Margin = new Thickness(2)
};
_button2.Click += Button_Click2; // Now this uses the second handler
grid.Children.Add(_button2);
Grid.SetColumn(_button2, 1);
Chart.AddControl(grid);
});
Chart.ChartControl.MouseLeftButtonDown += MouseClicked;
}
}
private void Button_Click(object sender, System.Windows.RoutedEventArgs e)
{
MessageBoxWindow.Show("Ok from Button 1");
}
private void Button_Click2(object sender, System.Windows.RoutedEventArgs e)
{
MessageBoxWindow.Show("Ok from Button 2");
}
//don't forget to unsubscribe from all events
public override void OnDisabled()
{
Chart.ChartControl.MouseLeftButtonDown -= MouseClicked;
_button.Click -= Button_Click;
_button2.Click -= Button_Click2;
}
Get Price on Click
It is possible to get the price value from chart at the point where the mouse is clicked, see below example.
public override void OnStateChanged()
{
if (State == State.SetDefaults)
{
SetDefaults();
SetParameters();
}
else if (State == State.Configured)
{
ClearDebug();
AddIndicators();
Chart.ChartControl.MouseLeftButtonDown += MouseClicked;
}
}
protected void MouseClicked(object sender, MouseButtonEventArgs e)
{
try
{
var price = Chart.FormatPrice(Chart.GetCurrentPrice());
MessageBox.Show(price);
}
catch (Exception exception)
{
Print(exception);
}
}
Disabling Plot Parameters in Optimization
During optimization the chart object gets disabled for faster execution. Therefore if you do set any plot parameters inside your OnStateChange method in your strategy you need to disable that for the optimizer.
private void InitializeIndicators()
{
_shortSMA = SMA(Close, ShortSMAPeriod);
_longSMA = SMA(Close, LongSMAPeriod);
if (!this.DataCalcContext.IsOptimization)
{
_shortSMA.Plots[0].Color = ShortSMAColor;
_longSMA.Plots[0].Color = LongSMAColor;
}
}
Addressing Date Time Issues
You can use our custom TWMProperty to create a more user friendly time picker for your parameters.
[TwmProperty]
[TwmTimeProperty]
[Display(Name = "Trade Start 1", GroupName = EntrySettings, Order = 14)]
public DateTime TradeStart1 { get; set; }
Below is an example of how to create a time filter in your TWM indicator or strategy with background coloring effect.
private const string TimeWindowSettings = "Time Settings";
[TwmProperty]
[Display(Name = "Trade Window 1", GroupName = TimeWindowSettings, Order = 56)]
public bool TradeWindow1IsOn { get; set; }
[TwmProperty]
[Display(Name = "Trade Start 1 (hour)", GroupName = TimeWindowSettings, Order = 57)]
public int Trade1StartHour { get; set; }
[TwmProperty]
[Display(Name = "Trade Start 1 (min)", GroupName = TimeWindowSettings, Order = 58)]
public int Trade1StartMin { get; set; }
[TwmProperty]
[Display(Name = "Trade End 1 (hour)", GroupName = TimeWindowSettings, Order = 59)]
public int Trade1EndHour { get; set; }
[TwmProperty]
[Display(Name = "Trade End 1 (min)", GroupName = TimeWindowSettings, Order = 60)]
public int Trade1EndMin { get; set; }
Trade1StartHour = 9;
Trade1StartMin = 30;
Trade1EndHour = 16;
Trade1EndMin = 30;
private void ColorInsideTimeWindow()
{
if (!TradeWindow1IsOn)
return;
var timeNow = ToTime(DateTime[0].Hour, DateTime[0].Minute);
var timeStart = ToTime(Trade1StartHour, Trade1StartMin);
var timeEnd = ToTime(Trade1EndHour, Trade1EndMin);
if (timeStart < timeEnd)
{
if (timeNow >= timeStart && timeNow <= timeEnd)
{
BackBrushAll = Brushes.DarkCyan;
}
}
else if (timeStart > timeEnd)
{
if (timeNow >= timeStart || timeNow <= timeEnd)
{
BackBrushAll = Brushes.DarkCyan;
}
}
}
private bool IsInsideTimeWindow()
{
if (!TradeWindow1IsOn)
return true;
var timeNow = ToTime(DateTime[0].Hour, DateTime[0].Minute);
var timeStart = ToTime(Trade1StartHour, Trade1StartMin);
var timeEnd = ToTime(Trade1EndHour, Trade1EndMin);
//Print("Now: "+ timeNow + " Start: " + timeStart + " End: " + timeEnd);
if (timeStart < timeEnd)
{
if (timeNow >= timeStart && timeNow <= timeEnd)
{
return true;
}
}
else if (timeStart > timeEnd)
{
if (timeNow >= timeStart || timeNow <= timeEnd)
{
return true;
}
}
return false;
}
private int ToTime(int hours, int minutes)
{
// Combine hours and minutes into an integer
int result = (hours * 100) + minutes;
// If the time is midnight (0000), return 1
return result == 0 ? 1 : result;
}
