If nifty future ltp at close is 8361 and i place amo sell order at 8361, then what will be the seen, if market opens at 8300

1)can my order will get executed at 8361, & get profit of 61 points from that point, 

2)or, sell order executed at 8300

3)& what will be the seen if market opens at reverse means at 8400
