1. Open a auction on vakantieveilingen.nl
2. Change the maxBid to the value you want to maximum spend. (whole euro's only)
3. Open the developer console in your browser (how do i do this?)
4. Paste the code in the console and hit enter

script.js

//-- Change this value to the maximum value that you want to pay
let maxBid = 20;
let lastPlacedBid = -1;

let bidBot = setInterval(function(){
  let countdown = document.getElementsByClassName('timer-countdown-label');
  let currentBid = parseInt(document.getElementById('jsMainLotCurrentBid').innerText);
  let nextBid = currentBid +1;
  if (nextBid <= maxBid && currentBid != lastPlacedBid) {
    if (countdown.length == 0 || parseInt(countdown[0].innerText) > 3) {
      console.log('🕰 waiting for last 2 sec to place bid');
      return;
    }
    
    console.log('💰 Placing new bid of €'+nextBid);
    document.getElementById('jsActiveBidInput').value =nextBid;
    document.getElementById('jsActiveBidButton').click();
    lastPlacedBid = nextBid;
  } else if (nextBid > maxBid) {
    console.log('🙅‍♂️ Current bid €'+currentBid+' exceeds your maxBid value (€'+maxBid+') you can update the max by `maxBid = 20;`');
  } else {
    console.log('🎉 We are the higest with €'+currentBid);
  }

  if (document.getElementById('jsActiveBidInput') == null) {
    if (currentBid == lastPlacedBid) {
      console.log('🎉 We won with €'+currentBid +'🎉🎉🎉🎉🎉');
    } else {
      console.log('🙅‍♂️ We lost the bidding 😡😡😡😡😡');
      setInterval(function(){location.reload()}, 3500);
    }
    
      clearInterval(bidBot);
  }
}, 200);
