Technical difficulties my a**. It's clearly the fear.
China is falling, Europe is falling,.. not a great day for trading..... unless you trade Bitcoin, of course

Actually it probably is a technical issue. The NYSE already has a process called "the curbs" that halt trading if the market falls more than 5% (could be less). It's meant to prevent a crash like what happened in 1929, so the market cannot just fall to zero or lose significant value (broadly) in a single day. The curbs were in the day of 9/11 for example and other dates that have caused negative turmoil to the markets.
I doubt they'd create some fake issue when they already have a regular process in place to address these issues.
LMAO I just cannot help but laugh about that 5% stop.. free market BAHAHAH no it's not. Where is the stop if it skyrockets 5% OH THERE IS NOT ONE.. fucking money pigs man.. such fucking pigs.
Still not completely against this isn't the start of a cyber war.. American airlines shutdown... NSYE... testing out their weapons perhaps..
I see you're side of it, but downside protection is good for anyone involved not just the pigs, as the saying goes "bears make money, bulls make money, pigs get slaughtered..."
If you're in it you get the downside protection too!
