Simple script I made for bustadice. It bets on 2x, doubles the bet amount on a loss and divides the bet by 4 if it's greater than 8 times the base bet otherwise by 2. It's not a set&forget script, it's risky but more profitable than plain martingale and it's manageable at a slow bet speed.

LD2WD4.js

var config = {
  baseBet: { type: 'balance', label: 'Base Bet', value: 128},
  betSpeed: { type: 'number', label: 'Bet Speed', value: 800},
  maxBet: { type: 'balance', label: 'Max Bet', value: 10000 }
}
Object.entries(config).forEach(c => window[c[0]] = c[1].value);
var s = t => new Promise(r => setTimeout(r, t));
for(let b = baseBet; ;b=Math.max(baseBet, b)){
  if (b > maxBet) break;
  await this.bet(Math.round(b / 100) * 100, 2).then(r => {
    b = r.multiplier >= r.target ? b / (b > baseBet * 8 ? 4 : 2) : b * 2;
  }).then(() => s(betSpeed));
}
