I think, scalper and the day traders should close their
trade positions before the major announcement! But, no problem for the long
time traders since they trade with wide SL levels.
I also avoid trading on Monday . I just see market and that day’s trading moves. Only some times I open positions on Monday . I fear That trend is not clear after Monday market set its position. ne can judge better what will be the next mood of market either it will go up or down. For trading You should fully watch market so that you avail good time and situation.
