Well done brewski.
If I were in your shoes, I'd struggle not to close out the trade. However, you are clearly made of sterner stuff - bits of you are brass - according to c_v's graphic at least! I don't suppose this will help much but, FWIW, this little exercise might assist psychologically with whatever you decide to do. Old school salesman refer to this as the
Abraham Lincoln Close or the
Balance Sheet Close. Applied to trading, it works like this: take a sheet of paper and draw a vertical line down the middle making two columns. In the left hand column write 'Close the trade' and in the right hand column write 'Let the trade run'.
Close the trade
In this column, write all the reasons for closing it out now. If you do this, you'll bank around £10k and be delighted. With good reason - great trade. However, the most important point to list is how you will feel if you
don't close it now and the market reverses and takes out your stop. Will you be happy, pleased that you stuck to your plan or will you feel gutted that you didn't close it when you had the chance to cash in your £10k profit?
Let the trade run
In this column, write all the reasons for not closing it out now and letting it run. Needless to say, the most important point to list here is how you will feel if you
do close it now and then the market takes off for a huge Santa Rally to end the year of fresh highs?
Once you've listed everything you can think of in each column, weigh each of them up to see if you're inclined to go one way or the other. Given that you'll never know when the top comes, it's reasonable to assume that you're going to have to take a draw down hit at some point. In your shoes, I'd be inclined to leave the trade as it is and hope the stop isn't hit before December. If you can last that long then, statistically, a Santa Rally occurs 70% of the time. IMO, the conditions under which one occurs are as favourable this year as they ever have been. Namely, low interest rates, strong borrowing, strong GDP and strong institutional equity investment coupled with a strong TA picture.
Good luck with your decision - I look forward to seeing how you play it!
Tim.
