I've mainly traded UK shares for the last 15 years. I'm doing more indexes at the moment. If I have £1 point guaranteed stop 300 points on Wallstreet the margin requirements is £1060.71. What does this mean if I hit the stop? Usually, I would assume loss of £300 plus stop premium. I haven't noticed anything extra where stops have been hit, but in extremis i.e. index lock up for 15 minutes leading to a gap down, would I lose the £1060.71? if not, should I be taking any notice of the higher figure on guaranteed stops?
Thanks in advance
