SPDR S&P 500 (SPY)

[need luck]

today's gap down was easy money
easy and also fast (the trade was - buy the open until gap close)
it was a textbook case

I missed it as I woke up rather after the fact
the 2nd jolt was risky, I would've not taken it, kudos who did
I just watched a bit the market, the dinosaurs were tired so I stayed put

then I was away all along not that was much to see other than selling
just came back, do some stuff and have to run again

now monday is going to be interesting
I would think that the selling pressure is going to accelerate by the aforementioned margin calls

then is close the eyes hold the nose and buying?
