A “bull” market is, in short, a market on the rise. It is characterized by a great deal of investor confidence, which can carry on for an indefinite period of time. When a currency breaks its resistance level, it is expected to continue rising, to move with a singularity of purpose. This is much like the way a bull is characterized. Additionally, it triggers herd behavior, as more and more investors will join in and invest more. The term “bull market” is therefore a good definition of a market behaving confidently.

“Bear” markets, on the other hand, are the exact opposite of bulls. Where prices fall and the investor mood is negative, the support level may be broken and the price will continue to fall. The most common explanation for the terminology here is that when a bear attacks its prey, it tends to do so by striking downwards. For a true bear market to be declared, a majority of currencies need to fall, however a single currency can be described as behaving “bearishly”.
