南京市场方管价格下跌，成交一般。早盘螺纹钢期货低开低走。唐山方坯跌20元，现普碳方坯含税出厂3510元。从当地贸易商了解， 贸易战对市场心态影响较大，除刚需低价有所成交，大多仍处在观望。商家进少出多，以完成销售任务为主。钢厂库存尚无压力，不过价格下调较之前有所放大。综 上所述，预计明日南京市场或继续回落。

In Nanjing market, prices fell and transactions were normal. Early-trading threaded steel futures open low. Tangshan billet fell 20 yuan, and now ordinary carbon billet with tax is 3510 yuan out of the factory. From the local traders, the trade war has a great impact on the market mentality. Most of them are still on the sidelines, except for the bargain just needed at a low price. Businessmen come in less and go out more, mainly to complete sales tasks. There is no pressure on steel mill stocks, but the price reduction has been enlarged. In summary, the Nanjing market is expected to continue to decline tomorrow. 价格方面：截止发稿时，永钢、沙钢三级大螺纹4210元(吨价，下同)，跌50元。

Price: Up to the time of submission, Yonggang and Shagang three-level large threads 4210 yuan (ton price, the same below), down 50 yuan.
