As I stated before on 12.17 post, I was sitting on paper profit of about 4% on 12.16, the day before the earnings report on Friday. It closed on 10.07.
Friday morning, it opened at 9.20, about 8.7% drop.
Besides the reason(s) behind its drop, it was WAY past the sell trigger, which was 9.84. I put the sell ticket at MARKET right away, taking about 5% loss on the position.
Painful? Yes. Necessary? You bet.
It is important to point out that BBRY ended up closing at 10.4 on Friday. That means, had I not sold my position and sat on it, I would have been ok.
I have to confess. After all these years of trading, things like this make me crazy still.
HOWEVER, I have to close the position. I have to follow the trigger every time it is signaled. You cannot question your system when the market opens. From 6:30 am to 1pm(Pacific Time), I execute the rules relentlessly. Thinking comes later after the close when you are examining the system.
That's when you have an open position. What about when you want to open a position and the open price went past the trigger?
I open the position at the open price anyway.
I do not have a reason. Based on my research, my spreadsheet always tells me to open it.
One thing I do differently is I reduce the size of the position because the gap between the open price and the trigger that would close that position is now bigger.
For example, AAPL buy trigger was 101 and sell trigger was 99 and last night's close was 100. How much I am willing to lose on this position if I open is $1.
If AAPL opened at 102, which is $1 more expensive than my buy trigger. What do I do? I buy less so the amount of loss that would incur when I sell at 100 stays the same.
Frankly, this happens rarely. Because I know my algorithm is a profitable strategy, I want to put as much as possible when I open a position. Therefore, I would still buy the same amount at 102, but would raise the stop loss price to 101 instead.
Again, the research shows me that it is more profitable to do this than sit and not buy just because it is now more expensive.
I realize what I described above is very uncomfortable for many to even think about executing. Like I said, I am still uncomfortable doing this as well. In fact, it makes me angry the market opened that way so that I am forced to make this kind of decision.
But sometimes, you just have to take what the market gives you. It will get only easier if you lose money. Therefore, I hope it gets tougher for you.
