It would also mean that in order for you to scale up and bet 200 your account balance would have to double. Therefore, by using this system you would be betting with 100 in a market with low risk but also in a very risky market. Since it is just an arbitrary number this system takes no account for what the market is like, instead it treats every market equally. This method is fairly common, both in sport and financial trading, but it is not a very good one. So, for each trade you would bet with 100 until you reach a bank of 2,000, then you can bet 200. You can decide to risk a certain sum relative to your capital, for example 100 per 1,000 in your account. So, we have established that in order to be profitable in the long run we must have a position sizing strategy that increases the bet size when we win and decreases it when we lose. If you play the roulette wheel or any other game in the casino, the house will always win but if you trade on Betfair, you trade against other traders and you can be profitable in the long run, if you apply the right positions sizing strategy. You increase your bet when you are on a role and not when you are in a slump. There is no doubt which is the riskier system, and which will give you a chance in the long run.Īs any gambler worth his beacon knows, Anti-Martingale is the way to go. With Anti-Martingale, we have only risked a total of 31 compared to 2,051. Not only that, but the risk is much lower as well. Here, Martingale outperforms by 35% to 0,2% and that’s significant! Not much perhaps but it is nearly double and look at the return on Total Bets. With five winning trades, Anti-Martingale outperforms Martingale with a return of 9 to 5. With Anti-Martingale the risk is smaller. In the first scenario with three losers followed by one winner we would now be down 1 instead of up one. So our new strategy is now to continue to bet 1 if we lose, and double when we win. This will move the market and you can no longer get the price you need.īut what if you did the opposite and doubled you bet every time you won, what would happen then? You could pick matches with slightly better odds than 2.00 to compensate for this, but that would change the probability of winning to below 50% in the long run.Īnd, no matter how good your guru status is, eventually you will run into a string of losers that will break your bank or be forced to place such large bets that there will be no one left to take your bet. On Betfair, you will have to pay commission on your winnings, usually 5%, and that alone will kill your strategy. In practice, however, you will run into problems. If you are, then you have a winning system, in theory. Perhaps you are a football guru and think you can pick the winner in matches priced at 2.00 more than 50% of the time. You could make the argument that in sports you can use your skill, which is something you cannot do in roulette. As long as there is someone willing to take the opposite side of the bet, you don’t have to worry about limits. ![]() On Betfair, a 50% chance of winning is the same as odds of 2.00, and it is possible to employ the Martingale system here. If you gamble online with an ordinary betting company you would also run into limits, but not on Betfair. If you were playing roulette in a casino you would most likely never get this far, you would simply run in to the table limit and would be forced to start over. Our actual bet is 2,047 since that is the total amount we have put down over eleven rounds to achieve our profit of 1. To bet 1,024 for 50% chance to win 1 is not a good profit to loss ratio, but it gets worse. ![]() Your total winnings are now 1 since your win on the last bet of 8 was 16 and your total bets were 15 (1+2+4+8). It would look like this, you bet 1 and lose, so you bet 2 and lose again, you bet 4 and lose and then you bet 8 and win. The ultimate Martingale system is to double your bet every time you lose on a game that gives you a 100% return on each win, like roulette. A Martingale system is simply a system where you increase your bet every time you lose in order to make up your losses. You may have heard of the Martingale system before. Learning how to apply a position sizing strategy is something anyone can do. With a good position sizing strategy, it become less important to predict the market. Position sizing is the second most important variable to a profitable system after an understanding of trading psychology.
