[Order activated, but subsequently auto closed, even if price was higher than stop order]

Thank you so much for the prompt response and clarification Anda. 

I assume in case of a short position then, one has to change the chart to "ask", to avoid a similar misinterpretation.

Have a good day.

[Order activated, but subsequently auto closed, even if price was higher than stop order]

Good day all,

I am a new trader and have a question in respect of auto closing of a limit order, upon reaching a specific price. I placed and order on19 Feb (Sunday), for a long position to be activated when Copper ($5 Mini Contract) reaches a value of 9 900, which it did on 21 Feb at 12:44. The system however auto closed the activated order at 9850 on 22 Feb, even if the lowest price for the day was only at 9850.6. May I please request further clarity as to why this would've been auto closed. If it 

 

 

Thanking you in advance for your advice / guidance.
