Thank you @Mercury, I am a perfect example of someone who is not willing to take small loss and eventually lose big chunk of their trading account. I kept moving stop loss further down in a hope that Dax30 would bounce back but it never happened since August 2018. It is never a good idea to 'keep moving your goal post' but if you do, you will learn a lesson the harsh way.
I will take some time off and will be back next year. Good luck with all your trading, have a nice xmas and happy new year to you all in advance.
