I cant figure out how many points would drop in day trade period, but i suppose if the index be dropped down to 19350 and break it down, maybe drop more and more.
nah, host who can control everything include raise, drop even immovability. On the basic side, they can make the good news to be bad news, bad to good. And the Technical side, include the huge type of this, RSI, MACD, SVC, OBV, but this probably base on something has been happened, so its meaningless.
You are absolutely right, luck is the most important in the trade, and ur life too.
