Есть скриптик один (бот) для сайта-рулетки. Мне нужно сделать так, чтобы при ставке в 1000 бот останавливался. Как это сделать?

Здравствуйте! Вопрос есть выше. Вот сам скрипт Что нужно дописать?

var maxstrike =15;
var stoploss = 50;// %
var min = 49;
var max = 95;
//--------------------------
var minbet = 5;
var balance = parseFloat(document.getElementsByClassName("Numbers HighlightedText UserBalance")[0].innerText);
var basebet;
var profit = parseFloat($('#LastBetInfoProfit').html());
var bet;
var betid;
var chance = 93;
var startbalance = balance;
var sbalance = balance;
var tick = 0;
var betting = true;
var maxbet = startbalance*stoploss/100;
var b;
var i = 0;
  b = balance*stoploss/100;
  while(i<maxstrike){
    b/=4;
    i++;
  }
  basebet = b;
  if(basebet < minbet) basebet = minbet;
  bet = basebet;
  document.getElementById('BetSizeInput').value = (bet).toFixed(8);
  document.getElementById('BetChanceInput').value = chance;
  $('#BetLowButton').click();
  balance = parseFloat(document.getElementsByClassName("Numbers HighlightedText UserBalance")[0].innerText);
  profit = parseFloat($('#LastBetInfoProfit').html());
  startbalance = balance;
  console.log('Game started at balance ',(balance).toFixed(8));
setInterval("roll()", 1000);
function roll(){
  tick+=1; 
  if (betting && tick >=15 || betid != parseFloat($('#LastBetInfoSecret').html())){
    betid = parseFloat($('#LastBetInfoSecret').html());
    profit = parseFloat($('#LastBetInfoProfit').html());
    balance = parseFloat(document.getElementsByClassName("Numbers HighlightedText UserBalance")[0].innerText);

    if(profit < 0){
      if(balance-bet*4 > startbalance*stoploss/100)bet*=4;
      else if(balance-bet*2 > startbalance*stoploss/100)bet*=2;
    }else{
      if(balance > startbalance){
          i = 0;
          b = balance*stoploss/100;
          while(i<maxstrike){
            b/=4;
            i++;
          }
          basebet = b;
         if(basebet < minbet) basebet = minbet;
          bet = basebet;
        console.log('Current balance ',(balance).toFixed(8),' profit ',(balance-startbalance).toFixed(8),
               '  Session profit ',(balance-sbalance).toFixed(8),'  ',(100*(balance-sbalance)/sbalance).toFixed(2),'%');
        startbalance = balance;
        maxbet = startbalance*stoploss/100;
      }
    }
    chance = (Math.random() * (max - min) + min).toFixed(2);
    if(betting && bet <= maxbet){
      document.getElementById('BetSizeInput').value = (bet).toFixed(8);
      document.getElementById('BetChanceInput').value = chance;
      if(Math.random() < 0.5){
        $('#BetLowButton').click();
      }else{
        $('#BetHighButton').click();
      }
      tick = 0;
    }else{
      betting = false;
      console.log('Game stopped at balance ',(balance).toFixed(8),'  Loss ',(startbalance - balance).toFixed(8));
    }
  }
