I chased after it a bit and lowered the leverage ratio. However, overall it is a relatively safe option speculation, with a maximum risk exposure of only a few hundred units, and the potential returns are still rising. I will continue to exercise this order.. Actually, it's not that I bought too little, but the liquidity of options is generally poor. The selling depth of doomsday options is only one or two thousand units.. More people need to learn option arbitrage in order to contribute depth
