I guess we all have our addictions/obsessions. Mine is the ticker tape for trading the stock market.
It's hypnotic, it's exciting, it's heartbreaking, too. You can never pick the absolute tops or the bottoms of stocks. The trick is to "know when to hold 'em and know when to 'fold em". You can't trade with fear, greed, or hope. A little luck does help and intuition :) (i.e., research)
Stocks were traded in fractions when I first started learning to trade and only the symbol for the stock was displayed - "MSFT". They switched to the decimal system in the Spring of 2001 and just last year, CNBC added the company name in addition to the stock symbol to the ticker - "Microsoft (MSFT)". It's so much more user friendly now for beginners and those of us that don't want to look up the symbols to find out the company name OR calculate in fractions. For awhile, CNBC's ticker tape didn't show the volume and that was awful. I really depend on the volume of trading to determine where the action is. Now, CNBC's ticker displays the volume of shares currently trading, again. It's like the pulse of the world market. I remember when the market reopened on September 17, 2001. Blinking Blood Red.
On my computer I have a full screen of streaming real time tickers for my selected stocks. It is totally fascinating (for me) to watch the bid and ask and volume of each exchange - all those flickering red/green lights. Yes, I am a small pototoe stock market junkie. I stay in touch with that ticker tape Monday through Friday for many years now. Even in a restaurant, I ask if they'll change the channel to 28. I don't need the volume, just the ticker streaming by. Of course, I like to pick the places to eat breakfast or lunch that let me watch CNBC. You'd be surprised how accommodating Tico folks are here. My dream was to live in Costa Rica and trade the market for a living.
I'm still learning to trade while I'm living the dream.
