Arbitrage in the context of "Trader (finance)"

Jurisdictional arbitrage is the practice of taking advantage of discrepancies between competing legal jurisdictions. It takes its name from arbitrage, the practice in finance of purchasing a good at a lower price in one market and selling it at a higher price in another. Just as in financial arbitrage, the attractiveness of jurisdiction arbitrage depends largely on its transaction costs, here the costs of switching legal service providers from one government to another.

The lower the exit costs for leaving the jurisdiction (unrestricted emigration, cheap travel, liquidity of assets) the more desirable and feasible it is. Conversely, high entry costs into the more favourable jurisdiction are an inhibitor on jurisdictional arbitrage; certain tax havens such as Andorra grant permanent residency rights to immigrants only if they meet certain criteria. Jurisdictional arbitrage is a significant concept in modern free market anarcho-capitalism.

Fixed-odds betting is a form of gambling where individuals place bets on the outcome of an event, such as sports matches or horse races, at predetermined odds. In fixed-odds betting, the odds are fixed and determined at the time of placing the bet. These odds reflect the likelihood of a particular outcome occurring. If the bettor's prediction is correct, they receive a payout based on the fixed odds. This means that the potential winnings are known at the time of placing the bet, regardless of any changes in the odds leading up to the event.

Fixed-odds gambling involves placing bets on events with predetermined odds. Bookmakers aim to create an overground, where the sum of probabilities quoted for all possible outcomes exceeds 100%, ensuring profit. Imbalanced books can occur, leading to higher or lower payouts than expected. The advent of the internet and betting exchanges has led to opportunities for fixed-odds arbitrage actions and Dutch books.

Hand signaling, also known as arb or arbing (short for arbitrage), is a system of hand signals used on financial trading floors to communicate buy and sell information in an open outcry trading environment. The system is used at financial exchanges such as the Chicago Mercantile Exchange (CME) and the American Stock Exchange (AMEX). The AMEX is the only US stock market to permit the transmission of buy and sell orders through hand signals as of 2003.

Traders usually flash the signals quickly across a room to make a sale or a purchase. Signals that occur with palms facing out and hands away from the body are an indication the gesturer wishes to sell. When traders face their palms in and hold their hands up, they are gesturing to buy.
