Help with finding update of swing

[YevhenShynkarenko]

Hello to all!
Having next trouble:
I want to have only one enter from current Swing indicator. Only once when my condition is accepted. And if it will be accepted on this Swing again - I need to do nothing and skip it. How can I do this?
F.e. I have next code:
swLow = price of the current Low Swing

if(trendup == true)
                {
                    currentLow = Low[0];
                    enterLongPrice = swLow;
                  
                    if(currentLow < enterLongPrice && hadEnterFromThisLong == false)
                    {           
                            priceInLongD = true;
                    }
                    if(priceInLongD == true && currentLow > enterLongPrice)
                    {
                        orderLong = EnterLongLimit(enterLongPrice, "Long Limit Order");

                        hadEnterFromThisLong = true;
                    }

What I need to add? And it doesn't matter will I have enter or not - I need to use the condition of currentLow < enterLongPrice only once. And I need to wait only when the next Swing will be plot, and only then I want to repeat this code.
Please, help!
Thanks!

Hello YevhenShynkarenko,

Thank you for your inquiry.

I would suggest comparing the current swing value to the previous swing value. If there is a change, the new swing value should be different. If it's the same, there wasn't a change. So, here's a quick example to do this. Please note that this is only an example. You'll need to change any variables as needed:

private double prevLowSwing = 0;
private double currentLowSwing = 0;

public override void OnBarUpdate()
{
     if (prevLowSwing == 0)
          prevLowSwing = Swing(5).SwingLow[0];

     currentLowSwing = Swing(5).SwingLow[0];

     if (currentLowSwing > prevLowSwing || currentLowSwing < prevLowSwing) // check if there is any change
     {
          // do stuff
          prevLowSwing = Swing(5).SwingLow[0]; // set prevLowSwing to the new swing value as the value has changed
     }
}

Please, let us know if we may be of further assistance.
