I have some questions regarding what happens to positions when an artificial price spike happens (that may be due to computer error rather than an actual market event). I am specifically referring to this spike and this event :
Time : 7:13am AEST (Melbourne time) 23/4/2020
Index : FTSE 100 Cash
Description : at 7:13 am FTSE 100 suddenly fell from 5764 to 5263 within 40 seconds. Then it retraced its entire fall suddenly.
What happens to my long positions in FTSE 100 when this occurs?
Will my long position stop losses be suddenly unnece
