In photography, they say that your 1001 photo will start to show that you are "improving".
I went broke over 10 times as a trader before improving .....
Want to know everything about photography ? Thousand of web sites, blogs, books, forums.
You can say the same about trading.
I should come out with a book (empty content) with the title "Paper trade 1000 stocks" before testing the markets ; you then can fill the empty pages with notes, comments, etc.
Photography has simple rules in order to shoot a basic photo (ISO, Aperture, Shutter).
So why do experienced photographer go nuts when they see a sudden event in front of them, forget their rules, and shoot in autofocus ?
Traders, with years of experience, will go nuts on a single stock if the "story" is amazing (forgetting the basic entry levels, stop loss, etc)
Good photos can be made when you take the time to compose ; meaning ? You plan the light, the object, the scene, etc ....
Good traders take the time to follow specific stocks, (or ETFs), plan the entry, focus, and wait like a sniper.
Great photos often are the work of snipers willing to wait .....
1) Find the target
2) Plan the trade (or photo)
3) Think like a sniper
