With immediate effect,all new orders with delivery date from August 18th (including the date of August 18th ) will be executed according to the new price; the confirmed contracts before August 18th (excluding the date of August 18th) will be executed according to the original prices stipulated on the contracts.

简释：
1."由于镍价上涨,上游原料行情紧张,为及时反映市场动态" 之句为了简洁起见缩略为一句话“由于原材料镍价持续上涨”.
2.后面的具体执行办法则尽量详细,并在括号内写出新订单（包括8月18日）执行新价格,老订单（不包括8月18日）执行老价格.这个一定要写清楚,否则会引起不必要的纠纷.
