martingale -
Doubling up gambling scheme.
Risk management theory | Masterclass | Financial | Inside Edge UK
At this point I'd like to introduce the martingale. This is a technique that involves increasing stake size as a run of losses
extends. Classically, the martingale comes into play with gambling games like blackjack or roulette, where a stake is doubled after
every sequential loss. When a win is made, the player gets back his losses and earns a "one-unit" win; the stake size is then reset. In
theory, with infinite money you'll always end up winning in the end. The martingale and its many permutations are popular systems for
trading. However the model is flawed as, in reality, you are liable to run out of money before your luck turns. Bad luck simply happens
with greater regularity than the capital required to fund the operation. I've actually witnessed red come up 23 times successively on a
roulette table. If I'd been running a martingale, it would have cost me Ј4 million to win back my Ј1 -- and even if I had Ј4 million, the
table limit would defeat me.

Didn't take me long to find out that the martingale is one of the classic gambler's ruin betting systems. I overlooked the fact that I'd need an infinite amount of money to be sure I wouldn't go broke. Hell, if I had an infinite amount of money, I wouldn't need a betting system.
