If there is anyone thinking about starting a diary I would thoroughly recommend it. It doesn't have to be for anyone to read as you can set up a blog which is for your eyes only. I decided to make mine available to anyone as a way to help my discipline. I thought that making it public would make me think twice about making decisions as a losing blog is no good to anyone. It certainly has helped although I have a long way to go. Or why not do it the old fashioned way with pen and paper.
Whichever tool you decide you have to be honest with yourself. There is no advantage to be had documenting stuff that you would rather write down instead of what you actually should write down. If you find yourself continuously losing it will help you make the correct decision of whether to redefine your strategy or concede defeat and give it up.
I am relieved that after three negative days, I am back in profit. Yesterday I had totalled £99.43 but wanted to gain the 57pence needed to reach my century. I decided to lay the draw midway through the first half of Toronto v Kansas and exited midway through the second accepting a loss of £18.66. The game ended 0-0. The irony is that when I had checked my P/L the Horse market had been adjusted to show £100.55.
