hi, hab da mal ne frage zu dem beispiel: Hier etwas für einige Interessierte, aber leider nur auf englsich. The Foundations Of Trading Backing: If you are BACKING a participant (horse, team or individual) you want that participant to win the event. It is exactly the same as placing a bet at your local bookmakers’. The betting exchanges use decimal odds as opposed to fractions that the bookmakers’ use. The way to work out an actual price that is on the exchanges I just by deducting “1”from the price on the screen. If the price on the exchange is 4.0, then deduct “1” from the price and this means that the price is the equivalent to 3’1. Similarly, if a price is 11’4, all you have to do is divide the first figure by the second figure and then add 1 to the total. Let’s say that the bookmakers’ price is 5’2. 5 divided by 2 is 2.5 and then add the 1 giving a total of 3.5. If you BACK a horse at 3.75 (11’4) for £100, your potential winnings will be 2.75 TIMES your £100 stake PLUS your £100 stake back. Laying: If you are laying a competitor, you are effectively betting that a horse, team or individual will lose the event. You may decide that a horse will not act on the prevailing ground or that a team can’t win as their striker is out injured and hence you would LAY that competitor. If someone else on the exchange wants to BACK a horse in a race then the exchange must find someone to LAY or accept that bet. However what you must remember is that LAYING a bet is very different to BACKING. When you place a BACK bet, your liability is the total amount of the stake is. With a LAY bet, your liability (how much you will have to pay out to the backer) is the amount of the stake MULTIPLIED by the prevailing odds. If you have LAYED a bet of £100 at 3.5, then your liability is as follows: LAY price (3.5) LESS 1 = 2.5 multiplied by the stake, £100. So your liability is £250. If the horse loses, you win £100. If the horse WINS, you will lose £250! Be very careful when laying as you CAN get seriously burned! Trading: Trading involves both BACKING and LAYING the same individual and taking the margin in between the two prices. Let’s say that we have BACKED a horse at 2.50 for £200. The price contracts to 2.46. We could then LAY someone else’s BACK bet of £200 @ 2.46. This effectively gives us a free bet and the maths is as follows: A) If the horse WINS: BACK bet £200 @ 2.50: Potential profit of: £300.00 LAY bet £200 @ 2.46: Potential loss of: £292.00 Balance: £8.00 B) If the horse LOSES: BACK bet of £200 @ 2.50: Potential loss of: £200.00 LAY bet of £200 @ 2.46: Potential profit of: £200.00 Balance: £200.00 So, broken down like this you can see that, if the horse wins, we win £8.00, the margin between the BACK and LAY prices. But, more importantly, we have built a position so that, if the horse wins we WIN but if the horse loses, we don’t lose a red cent! Is that cool or what? Taking it a step further: We could actually take it a bit further by adding a further LAY to ensure that we win something on the race. The “paper profit” of £8 is divided by the LAY price (in this case 2.46) and this gives us a figure of £3.25 so we would LAY a total of £203.25 @ 2.46. This is the maths side of it: A) If the horse WINS: BACK bet of £200: Potential profit of: £300.00 LAY bet of £203.25: Potential loss of: £296.75 Balance: £3.25 B) If the horse LOSES BACK bet of £200.00: Potential loss of: £200.00 LAY bet of £203.75 @ 2.46: Potential gain of: £203.25 Balance: £3.25 soweit ist mir das eigentlich schon klar, aber auch irgendwie unlogisch. wenn ich 200€ auf 2.5 setzt krieg ja 500€ raus aber muss auch durch die verlorene laywette: 203,25 * 2.46 = 500€ zahlen. und hab keine 3.25 gewinn. kann mir das vielleicht jemand erklären mfg
