What was the stock sold at? Ave price...
Looks like you had a stop loss set 3c below as a the gap up open would have dragged your SL from 16.5 to 19.5 or 20. After the gap up it would have auto triggered a take profit on retracement. Your dealing with pros I hope you realize.
Don't take this the wrong way but if you don't know how different types of stop losses or take profits work you really need to sit down with someone who can explain this to you and as soon as you can. The bots working a stock will hunt you with ease.
If you are new to iress I suggest learn the different types of trading orders available. I don't even understand them sometimes as if your broker has Chi x and ASX duality your stop losses can get sucked into the dark pools.
Hope this helps and good luck.
