Holding a position open over a weekend when the markets are closed carries an undefinable amount of risk... who are we to say that come sunday the price doesnt gap against us 1000 pips.
Just my idea about it...
Do you agree with the random walk in markets hypothesis? If you google random walk, you will see it. What I learned at a trading desk 2 years ago was that we are all just coin flippers like you say. And we can simply hope for the best.
So does that make manually executing and evaluating L2 almost useless? Unless you have an algo written to trade based off of very minute changes in the order flow?
I used to travel to Switzerland from NY at least once a month just to enjoy while trading. Skiing in the alps while waiting on your returns was pretty fun :D
definitely doable, go for it, and send us some pictures!
