I don't understand the contract, what does this fee -2.0 mean? Assuming I open 100u at 10 times, how does that work?

$BERA looks at the 15-minute line, both ends are slowly contracting, it's another domestic server scam, quantitative trading has already entered, brothers, withdraw, otherwise it will be a double kill for both long and short positions. Just a reminder, the overall trend is downward, but considering the short-selling costs, it's not worth betting on this slight fluctuation. If you want to trade, it should be in that range; buying high and selling low can still be profitable, but it can only be for ultra-short-term trades.
