Why Odds and Edge?

Anyone that has ever been to Las Vegas can see the money that the casinos spend to lure the gambler into their casino. The casinos make their money, an enormous amount of money, by maintaining their edge. In the collection of all games that a casino runs, they still maintain around 4.5% edge. That means that out of every dollar that is brought in to the casino, 4.5 cents stay there. Some people hit the jack pots, some people lose everything they have, but the casino, on average, makes 4.5%. For the casinos, it is not gambling, it is a game of odds, probabilities and they know their edge. The more gamblers come in, the more money they bring with them, the more the casino makes, as long as they maintain their edge.

In trading, the trader runs their own casino. If a trader wins 80% of the time, makes $200.00 every time he wins and loses $100.00 every time he loses, on average the trader makes $140.00 per trade. As long as the trader maintains his ratios, his edge, he will make, on average, $140.00 every time he executes a trade.

This is a very important statistic for a trader. Being aware of these numbers allows traders to weather draw downs, stick to their system, eliminating hesitation and managing their trading correctly.
