So I've found the right script for FreeBitCo.in
Check it bellow.
var minValue = 0.00000001;
var maxLoss = 0.0000001;
var aimedProfit = 0.000005;
var maxOps = 50;
// Don't touch anything after this
var endResult = 0;
var ops = 0;
// Bets a given amount on a given button and returns the value ot the callback
var bet = function(value, button, callback) {
var buttonName = button ? 'lo' : 'hi';
// We use site's api
$.get('?op=double_your_btc&m=' + buttonName + '&stake=' + value + '&multiplier=2&jackpot=0', function(result) {
var splittedResult = result.split(':');
// We update the account balance, as we have it juste there
$('#balance').html(splittedResult[3]);
// We finally call the callback
callback(value, button, splittedResult[1] === 'w');
}
);
};
// Main Martingale's method
var martingale = function(value, button, result) {
// We apply Martingale algorithm
if (result || (value >= maxLoss && maxLoss !== 0)) {
button = !button;
newValue = minValue;
}
else
newValue = 2 * value;
// We compute new final result
if (result)
endResult += value;
else
endResult -= value;
// We start over (and log misc data)
console.log((result ? '+' : '-') + value);
ops++;
if ((ops < maxOps || maxOps === 0) && (endResult < aimedProfit || aimedProfit === 0))
bet(newValue, button, martingale);
else {
console.log('Martingale finished in ' + ops + ' operations!');
console.log('Result: ' + endResult);
}
};
// Init operation
martingale(minValue, false, false);
