In a market with negative atmosphere, even iif t rebounds very soon sellers will  reduce their goods thus pull down ithe ndex . Just like today.  

afraid in  the coming one week or so situation will likely be the same,

that is :
open high, close low or less high.
Open low, close low.

But large daily fluctuation is good chance for one-day sin trading.
And negative market atmosphere favours put warrant trading.
