comment Intraday Data - Stylized Facts?
Here is one: Currencies trade 24/5 and equities are traded from market open till market close. And not even that is a stylized fact, take a look at the Hong Kong equity market and you will encounter numerous unannounced (sometimes multi day/weeks) trading halts. Or consider the many locked markets or stocks in opening auctions that can last hours if not throughout the whole session (see Tokyo stock exchange for plenty examples). In summary nothing is stylized which is why risk taking approaches need to be dynamic and adaptive.

comment Why most of apple stock price since 10years have been gained overnight?
What is your question? The simple answer to the question in your header is that more price impacting news hits the wires after market close and before market open. Also, Apple derives most of its revenues and earnings from outside the U.S. Whats so surprising?

comment Why would there be a positive risk-free rate?
It would be nice the next time you almost entirely change your question to let a little bit of time pass before choosing an answer so everyone gets a chance to adjust their answers. What you ask now is very different from the question you initially asked.

comment Why should we expect geometric Brownian motion to model asset prices?
Sure it is, with weeks/months delays which I consider fast in terms of lost IP but long enough in terms of being able to capture some alpha before the rest of the street catches on.

comment Why would there be a positive risk-free rate?
Your point is another academic anecdote that unfortunately floats around way too often. a) Treasury bills are not risk-free. US Government debt is not even triple A rated anymore. b) I explained that depending on utility certain market participants are not content with generating 2% per annum, no matter the risk incurred. c) leveraging such "investment opportunity" is an urban myth: You assume the interest you pay on a loan to purchase risk-free assets is lower than the yield on such instruments -> certainly not true in most cases. Also, bidding such instruments pushes down yields even further

why models allow for it to be only positive?

comment Hedging future USD cost using different IR and forwards
What is the exact question? I suppose it is how many euros you need to pay 6 months hence in order to receive USD 2500? That would be 1/1.30 EUR/USD * 2500 USD = EUR 1923.07. No need for anything else. You look to hedge spot fx risk. This provides the hedge. Keep in mind there does not exist one single hedge in the universe of finance that does not expose you to any risk. It all comes down to which risks you specifically do not want to be exposed to and which risks you can accept exposure to.

comment What software should I use for forex arbitrage?
What do you want to arbitrage? I suggest it may be a little late to the game (around 5-10 years to be honest) when you could broker arb in the fx world or meaningfully make money from triangular arb. Also, given you are dependent on json feeds which are inherently "slow" you will not benefit from a system architecture that is faster than your weakest link. Please elaborate on your question because it is very unclear what you actually want!
