 读取./sql/08_trade.sql，完善trade_info_view视图逻辑，加入close_date和close_price信息。
+---
+读取./sql/08_trade.sql，然后多加一个子表，子表名叫trade_close_fee，子表逻辑字段为:
+id UUID DEFAULT gen_random_uuid() PRIMARY KEY，
+trade_id UUID NOT NULL,
+close_fee numeric(10,2) NOT NULL CHECK (price >= 0.00) DEFAULT 0.00,
+deleted BOOLEAN NOT NULL DEFAULT FALSE,
+created_at TIMESTAMPTZ NOT NULL DEFAULT CURRENT_TIMESTAMP,
+updated_at TIMESTAMPTZ NOT NULL DEFAULT CURRENT_TIMESTAMP
+
+完善trade_info_view视图逻辑，加入trade_close_fee信息。
