The so-called arbitrage is to avoid risks while gaining profits through hedging.

If you expect to go up and then go long, it's not arbitrage. Gambling right wins, gambling wrong loses, high risk and high income.

During the bull market, the short-term increase can be greater than the long-term increase, so arbitrage can get more profits in the short term and short the risk of misjudgment in the long term. This is arbitrage.

The purpose of arbitrage trading is not high income, but low risk.
