How to Manually Pause a Strategy?

[givemefood]

Hi,

I have a simple strategy to which I would like to add a button on the right like shown in the screen shot. The button is to pause/unpause a strategy. This will allow me to let the strategy run but only enabled when I want it to execute trades. Are there code samples you can share that I can start with?

Please assist.

Thanks.

Hello givemefood,

I am not aware of anything that I could link to which shows that but really you are just asking about using a bool variable here. A button can toggle a bool variable which your strategy can use in its conditions to know if it can trade or not.

Can you point me to any reference material I can use to add the button? I can add a bool variable within the code based on the action taken on the button. Thanks.

Hello givemefood,

You can find an example of adding buttons to charts in the following links.

With someone's help I got the following code built. But I get many errors. Can you please check what might be wrong with it?


// Declare a bool variable to control the strategy
bool strategyPaused = false;

protected override void OnBarUpdate()
{
// Check if the strategy is paused, if it is, exit the method and do not execute any trades
if (strategyPaused)
return;

// Strategy logic goes here
}

protected override void OnRender(ChartControl chartControl, ChartScale chartScale)
{
// Define the button width and height
int buttonWidth = 100;
int buttonHeight = 30;

// Define the button position on the chart
int buttonX = chartControl.Bounds.Width - buttonWidth - 10;
int buttonY = 10;

// Draw the button on the chart
if (GUI.Button(new Rect(buttonX, buttonY, buttonWidth, buttonHeight), strategyPaused ? "Resume" : "Pause"))
{
// Toggle the strategyPaused variable when the button is clicked
strategyPaused = !strategyPaused;
}
}

Hello givemefood,

What errors are you seeing?

From the code you provided that is not valid so that would not compile. OnRender is also not where you would add buttons.

Did you try the help guide sample that I previously linked which adds buttons?
