MartinG's Martingale

/*////////////////////////////////

MartinG's Martingale, is just a classic martingale strategy that makes it
really easy to configure.

Just tell it what streak protection you want (maxLossStreakPerRound) and how
much you can afford to loose if there is a streak (costOfLoosingRound).

Also you can set the desired cashout.

There is no need to calculate the base bet or multiplier.

NOTE: Base Bet will be printed in console. If your base bet is less than 1 bit,
that probably means your costOfLoosingRound is too low or your
maxLossStreakPerRound is too high.

var cashout = 1.35;
var maxLossStreakPerRound = 3;
var costOfLoosingRound = 500;

// No need to change anything below this line

var baseBet = 1;

var p = baseBet * (cashout - 1);

var losses = 0;
var lostBits = 0;
var nextBet = baseBet;

function loose(_lostBits, _nextBet, _losses) {

		if(_losses >= maxLossStreakPerRound) {

			return _lostBits;

		} else {

			_lostBits = _lostBits + _nextBet + p;
			_nextBet = (_lostBits + p) / (cashout - 1);
			return loose(_lostBits, _nextBet, _losses + 1);

		}

}

baseBet = costOfLoosingRound/loose(0,baseBet,0);
p = baseBet * (cashout - 1);
nextBet = baseBet;

console.log("Base Bet: " + baseBet);

var playing = false;

engine.on('game_starting', function(info) {

	engine.placeBet(Math.floor(nextBet)*100, Math.round(cashout * 100));
	playing = true;

});

engine.on('game_crash', function(data) {

	if(!playing) {
		return;
	}

	playing = false;

	if(engine.lastGamePlay() == 'LOST') {

		losses = losses + 1;
		lostBits = lostBits + nextBet + p;

		if(losses >= maxLossStreakPerRound) {

			losses = 0;
			lostBits = 0;
			nextBet = baseBet;

		} else {

			nextBet = (lostBits + p) / (cashout - 1);
