So ... Will they allow the market to free fall like John Mayer?
No. Circuit breakers activate @ -7%, -13%, and -20%— a 15min halt goes into effect. This for the daily session; crash can continue the next day. Most likely won't happen today but good to know in case your chart "freezes".
Many propfirms ban trading below 5%. Which we are way below now. Careful. ⚠️ SPYQQQES1!NQ1!TSLA
