#套利交易策略 When operating USDT, I mainly use cross-exchange arbitrage trading strategies. Due to occasional slight price differences of USDT between different exchanges, I monitor prices in real-time through API tools. When I find a price difference of over 0.2% between, for example, Binance and OKX, I simultaneously buy on one side and sell on the other to lock in risk-free profits. This type of arbitrage usually requires quick reactions and sufficient funds in both accounts, while also paying attention to withdrawal speed and transaction fee costs. Although the profits are not large, they accumulate to a quite considerable amount and are one of the stable low-risk quantitative trading methods.
