That's why I try not to have any position by Friday night or reduce my exposure. As from last few weeks by the time on Saturday morning when SPI closes I am in decent profit and when on Monday market opens, it opens with like 150-200 points in other directions and and there goes my profit and bit more. So now I don't take any positions over weekend.
Anyway, from last few weeks what market has done, if it does again the same thing then Monday will be closing in +ve. But I will wait for trend to set first and then Jump. Any long position will be small and short will be large.
Here is weekend trading, not as bad as I expected. Which may change by Monday morning.
