Bustadice's default martingale script is less configurable than bustabit's so I made a bustadice version out of it. (this is for use on bustadice).

default-bab-mart-bustadice.js

var config = {
  baseBet: { value: 100, type: 'balance', label: 'base bet' },
  stopBet: { value: 1e8, type: 'balance', label: 'stop if bet >' },
  basePayout: { value: 2, type: 'multiplier' },
  stopPayout: {value: 20,type: 'multiplier',label: 'stop if payout >'},
  lossBet: {
    value: 'increase', type: 'radio', label: 'Bet On Loss',
    options: {
      base: { type: 'noop', label: 'Return to base bet' },
      increase: { value: 2, type: 'multiplier', label: 'Multiply bet by' },
    }
  },
  winBet: {
    value: 'base', type: 'radio', label: 'Bet On Win',
    options: {
      base: { type: 'noop', label: 'Return to base bet' },
      increase: { value: 2, type: 'multiplier', label: 'Multiply bet by' },
    }
  },
  lossPayout: {
    value: 'increase', type: 'radio', label: 'Payout On Loss',
    options: {
      base: { type: 'noop', label: 'Return to base payout' },
      increase: { value: 2, type: 'number', label: 'Increase payout by' },
    }
  },
  winPayout: {
    value: 'base', type: 'radio', label: 'Payout On Win',
    options: {
      base: { type: 'noop', label: 'Return to base payout' },
      increase: { value: 2, type: 'number', label: 'Increase payout by' },
    }
  },
  delay: { value: 100, type: 'number', label: 'Bet Speed' }
};

this.log('Script is running..');
var currentBet = config.baseBet.value;
var currentPayout = config.basePayout.value;

function roundBit(bet) {
  return Math.round(bet / 100) * 100;
}

function sleep(ms) {
  return new Promise(resolve => setTimeout(resolve, ms))
}
for(;;){
  const result = await this.bet(roundBit(currentBet), currentPayout);
  if (result.multiplier >= result.target) {
    if (config.winBet.value === 'base') {
      currentBet = config.baseBet.value;
    } else {
      console.assert(config.winBet.value === 'increase');
      currentBet *= config.winBet.options.increase.value;
    }
    if (config.winPayout.value === 'base') {
      currentPayout = config.basePayout.value;
    } else {
      console.assert(config.winPayout.value === 'increase');
      currentPayout += config.winPayout.options.increase.value;
    }
    this.log('We won, so next bet will be', currentBet/100, 'bits @ ', currentPayout + 'x')
  } else {
    // damn, looks like we lost :(
    if (config.lossBet.value === 'base') {
      currentBet = config.baseBet.value;
    } else {
      console.assert(config.lossBet.value === 'increase');
      currentBet *= config.lossBet.options.increase.value;
    }
    if (config.lossPayout.value === 'base') {
      currentPayout = config.basePayout.value;
    } else {
      console.assert(config.lossPayout.value === 'increase');
      currentPayout += config.lossPayout.options.increase.value;
    }
    this.log('We lost, so next bet will be', currentBet/100, 'bits @ ', currentPayout + 'x');
  }

  if (currentBet >= config.stopBet.value) {
    this.log('Was about to bet', currentBet, 'which triggers the stop');
    break;
  }else if (currentPayout >= config.stopPayout.value) {
      this.log('Was about to bet', currentPayout+'x', 'which triggers the stop');
      break;
    }
  await sleep(config.delay.value);
}

Appears to be working perfectly for me.. If you want to be more specific about the issue, I can check it out =]

Hi,

Would u like help with a bustadice martingale script which '+ bits' feature instead of 'x bits'

It won't be called martingale. For the same target adding bets after loss or win.
