stopAfterWin()  - Stop the Martingale Bot After Winning
*/
 
//Settings
var initialBet = "0.0000005";//CHANGE THIS TO YOUR START BET LEAVE EVERYTHING ELSE ALONE
var chanceToWin = "49.5";
 
//Your don't need to change anything below here
var payoutMultiplier;
var martingaleMultiplier;
var nextBet;
var bStopNow = false;
var bStopAfterWin = false;
 
function start() {
    payoutMultiplier = 99/parseFloat(chanceToWin);
    martingaleMultiplier = payoutMultiplier/(payoutMultiplier-1);
    nextBet = parseFloat(initialBet);
    roll();
}
 
function stopNow() {
    bStopNow = true;
}
 
function stopAfterWin() {
    bStopAfterWin = true;
}
 
function roll() {
    var hi_lo = Math.round(Math.random());
    if (hi_lo == 0)
        hi_lo = 'hi';
    else
        hi_lo = 'hi';
   socket.emit("bet", csrf, { chance: chanceToWin, bet: nextBet.toFixed(8), which: hi_lo });
}
 
socket.on("wins", function (data) {
    if (bStopNow || bStopAfterWin)
    {
        bStopNow = false;
        bStopAfterWin = false;
        return;
    }
    nextBet = parseFloat(initialBet);
    roll();
});
socket.on("losses", function (data) {
    if (bStopNow)
    {
        bStopNow = false;
        return;
    }
    nextBet = nextBet * martingaleMultiplier;
    roll();
});
socket.on("jderror", function (data) {
    roll();
});
