Share a few obscure trading arbitrage strategies 1. Weekend arbitrage Traditional market making teams exit on weekends, and the BTC/ETH per basis and spot prices often widen on Sunday nights; After the market opened on Monday, the large funds quickly converged and returned to the market to pull back the price difference. On Sunday night, check the price difference and open the exchange to compare spot prices and perpetual contracts (PERPs) If PERP is more than 0.8% more expensive than spot, it means a gap has emerged. Choose a platform that can handle both spot and contract transactions: Binance, OKX, Bybit, or any other platform. At the same time, open a short position on PERP and buy an equal amount of spot goods, so that the price fluctuations offset each other. Only bet that the 0.8% price difference will converge. If the price difference falls below 0.2% on Monday, close the position on both sides. 2.
