I agree with you, Friday is a pretty chaotic market condition. because of market movements until Friday, the movement was very fast and chaotic. actually I just got a margin call on Friday. because indeed the market movement is very chaotic, so it is very difficult to analyze, but I was forced to trade. it made me suffer a big loss in my trade. and but it produces a technical trading style using graph operations on two ... and if that's the situation, then all we have to do is prevent trading days ... that there might be changes in the design of the design movement .... but I think there really isn't there are bad days for business ... many people say thursday and saturday are bad days to deal with it.
