说出你想怎么交易。NX80 把它变成规则，诚实地回测，并在你的账户上运行。

NX80 将执行的规则

strategy                = "funding_book_long"
pair                    = ETHUSDT   # spot
entry.when              = all of:
  futures.funding_rate  = < 0   # ETHUSDT perpetual
  book.bid_usd(1%)      = >= 2 × book.ask_usd(1%)
order.side              = buy
order.type              = limit @ best_bid
order.size              = 10% of balance
exit.take_profit        = +3.0%
exit.stop_loss          = −1.5%
check.every             = 1m

示例为预先准备。用你自己的话写：规则由 AI 根据你的描述生成——NX80 会展示这些规则，并说明暂时做不到什么，你在运行前进行核对。
