Very important how US indices will close today. All week long we had a non-stop selling , and if today we get the close at the lows (ideally close to support line), I would not be surprised to see strong follow through on Monday as well, even gap lower and limit down maybe.
Prices often continue trending on Mondays in the same direction as Friday close. So given it will be 1 day before most important and unpredictable elections in recent history (and I am not even speaking COVID here), a lot of investors might decide to rush for the way out all at once, especially, if today is another ugly day in the making...
