For two nights in a row I sat glued to the big screen watching the tennis. Congratulations Barty & Djokovic. Watching those two great champions, the difference in their body language and facial expressions when playing to their off court personalities so very different. They appear to go into a completely different zone, call it white line fever, or any other name you care to give it.
I've read a number of posts on HC over the years from a few posters whom I have admired, and they too have stated that when they are trading everythig else is totally irrelevant, nothing else exists, just them and the market.
