limit hit but trade didnt close?

[Guest willif]

 this morning i put on a trade set my stop and limit as i had to leave my computer.

 

i came back to check my trade and unfortunately was stopped out. after looking back at the trade the market actually went 0.3 points over my limit at this point i would of thought my trade would close and i would of made a profit as it has done on the past days, but the trade did not close and the market went the other way until it hit my stop.

 

If anyone can help me on the reason it didn't close i would be very grateful??

 

Thanks Will

Hi ,  It was the spread. If you go to options > price and toggle between ask and bid you will find one hit and the other didn't. To reduce the chances of this happening again set the price to mid.
