Trump canceled planned strikes on Iran after requests from Iran and other Middle Eastern states, CNN reported; sources said Saudi Crown Prince phoned Trump to express concern.

Leighton added that after five months of conflict Iran faces economic and military pressure, and any diplomatic pressure from Tehran may reflect an effort to buy time to preserve itself.

1、滬深兩市7月31日總成交量連增三日至2.55萬億，爲連續第十五個交易日低於20日均線（2.57萬億），不過正逐步靠近。 2、7月31日衡量A股槓桿水平的融資買入額佔A股流動市值之比降至7.60%，處於過去一年波動區間下限附近，年內一直圍繞着10%波動，5月以來波動明顯加劇。 -------- 注：1、兩市成交量反映了各大機構、遊資、廣大散戶對A股看法，高於均線代表總成交量升高，市場情緒偏樂觀，低於均線代表總成交量下降，市場情緒降溫。 2、2015年以來，A股槓桿水平大部分時候維持在6%-10%，槓桿率超過10%意味着市場活躍度較高，可能接近或者處於牛市。達到15%以上意味着市場有過熱風險，需要警惕風險。
