Limit number of calls some function in JS

Ok, I have little script which run in loop mode. It's for gambling. This is idea: I flip coin infinity times (loop) and i have chance 50/50 for both sides. But, in some point I will get 5 times in row "Number side": ...,head, number,head, NUMBER, NUMBER, NUMBER, NUMBER, NUMBER,... And I need to limit script to call function if get 5 times in row "number side". In my case, I have function multiply() and that function was call sometimes. So, I need to limit number of calls multiply() functions for eg. 5 or 4.. So, if script call function multiply() 5 times in row, it will do something (eg. show alert or something). This is script:

var startValue = '0.00000001', // Don't lower the decimal point more than 4x of current balance
            stopPercentage = 0.001, // In %. I wouldn't recommend going past 0.08
            maxWait = 500, // In milliseconds
            stopped = false,
            stopBefore = 3; // In minutes
     
    var $loButton = $('#double_your_btc_bet_lo_button'),
                    $hiButton = $('#double_your_btc_bet_hi_button');
     
    function multiply(){
            var current = $('#double_your_btc_stake').val();
            var multiply = (current * 2).toFixed(8);
            $('#double_your_btc_stake').val(multiply);
    }
     
    function getRandomWait(){
            var wait = Math.floor(Math.random() * maxWait ) + 100;
     
            console.log('Waiting for ' + wait + 'ms before next bet.');
     
            return wait ;
    }
     
    function startGame(){
            console.log('Game started!');
            reset();
            $loButton.trigger('click');
    }
     
    function stopGame(){
            console.log('Game will stop soon! Let me finish.');
            stopped = true;
    }
     
    function reset(){
            $('#double_your_btc_stake').val(startValue);
    }
     
    // quick and dirty hack if you have very little bitcoins like 0.0000001
    function deexponentize(number){
            return number * 1000000;
    }
     
    function iHaveEnoughMoni(){
            var balance = deexponentize(parseFloat($('#balance').text()));
            var current = deexponentize($('#double_your_btc_stake').val());
     
            return ((balance*2)/100) * (current*2) > stopPercentage/100;
    }
     
    function stopBeforeRedirect(){
            var minutes = parseInt($('title').text());
     
            if( minutes < stopBefore )
            {
                    console.log('Approaching redirect! Stop the game so we don\'t get redirected while loosing.');
                    stopGame();
     
                    return true;
            }
     
            return false;
    }
     
    // Unbind old shit
    $('#double_your_btc_bet_lose').unbind();
    $('#double_your_btc_bet_win').unbind();
     
    // Loser
    $('#double_your_btc_bet_lose').bind("DOMSubtreeModified",function(event){
            if( $(event.currentTarget).is(':contains("lose")') )
            {
                    console.log('You LOST! Multiplying your bet and betting again.');
                   
                    multiply();
     
                    setTimeout(function(){
                            $loButton.trigger('click');
                    }, getRandomWait());
     
                    //$loButton.trigger('click');
            }
    });
     
    // Winner
    $('#double_your_btc_bet_win').bind("DOMSubtreeModified",function(event){
            if( $(event.currentTarget).is(':contains("win")') )
            {
                    if( stopBeforeRedirect() )
                    {
                            return;
                    }
     
                    if( iHaveEnoughMoni() )
                    {
                            console.log('You WON! But don\'t be greedy. Restarting!');
     
                            reset();
     
                            if( stopped )
                            {
                                    stopped = false;
                                    return false;
                            }
                    }
                    else
                    {
                            console.log('You WON! Betting again');
                    }
     
                    setTimeout(function(){
                            $loButton.trigger('click');
                    }, getRandomWait());
            }
    });

I need this to stop losing points more and more if get 5 times in row "lose" because script always multiply by 2 if lose. And script must multiply if lose, it's rule for gambling :)

Create Global variable:

var startValue = '0.00000001', // Don't lower the decimal point more than 4x of current balance
            stopPercentage = 0.001, // In %. I wouldn't recommend going past 0.08
            maxWait = 500, // In milliseconds
            stopped = false,
            stopBefore = 3, // In minutes
            multiplyCalls = 0; // <--- Added this global

Add to variable and If to test value

 function multiply(){
            if(multiplyCalls <= 5){ // test multiply
                var current = $('#double_your_btc_stake').val();
                var multiply = (current * 2).toFixed(8);
                $('#double_your_btc_stake').val(multiply);
                multiplyCalls++; // increment
            }else{
                console.log('you lost');
            }
    }

Reset your variable on game reset

function reset(){
    $('#double_your_btc_stake').val(startValue);
    multiplyCalls = 0; // reset value
}

Ok, I find solution:

        stopped = false,
        stopBefore = 3; // In minutes
        multiplyCalls = 0; // <--- Added this global

var $loButton = $('#double_your_btc_bet_lo_button'),
                $hiButton = $('#double_your_btc_bet_hi_button');

});

Thanks @patrick murphy

SO, I increment counter in "lose" and reset counter in "win" section. Thanks all :)

You can simulate a c-style block scoped static variable like this:

function foobar() {
    this._callCount = this._callCount || 0; // static scoped variable
    if (this._callCount++ >= 5) {
        // reached over 5, exitting.
        return;
    }
    // do something else
}

Can't you just create a global variable for function call count and increment it every time the function is executed? Plus add some conditions in the function what shall happen when you reached the limit.
