I gave pomodoro a try years ago, but failed. It simply doesn't fit my personality, don't like deadlines and time pressure.
Instead, I put my tasks in a Moleskine notebook, mixed with other notes and ideas of mine. In front of each task I put a square box, to be checked when the task is completed in the future. Usually tasks are 1-2 hours long, they are for evenings, longer tasks are for weekends. It's crucial to keep tasks small, no longer than 1 day of work, so split big tasks into small. This is crucial, as abstract tasks lead to procrastination and make you lose focus. The checkbox gives satisfaction when done and remains in the notebook, so that you can see a lot of completed by reviewing your notes.
I use this technique for 3 years now and it works for me. Not sure if it's known by other name as I came to it myself. Hopefully, this can be useful for others as well.
It's 2 different things to have a to-do list and use the Pomodoro technique.
The first one is made to plan your day and clear your mind, whereas the latter is made to help you go through that list while being as productive as possible.
Again, it very much depends on the persona. All I need to be productive is a clear to-do list and no destruction, to focus on my work. No extra techniques, like Pomodoro, is necessary in my case.
If you can get past the washi tape and calligraphy brigade, and sprinkle a few reviews/mid-term plans, it’s actually pretty effective (at least I have found it so).
At first you pay taxes in the country the company you work for is registered (there might be b2b options, which might differ). Then you pay rest in the country where you have a tax residency.
In your example, at first you pay taxes in Germany and if Estonian taxes are bigger, you pay the difference there.
I am partly working for an Italian company from Germany. Billing is very simple. I invoice the Italian company according to the so-called reverse charge procedure: My invoice does not include VAT, but only the European VAT number of my and the customer's company. The customer must settle the VAT with his tax office. I only have to inform my tax office at regular intervals about the turnover with the individual companies, so that the European tax authorities can check whether the customer has declared his taxes correctly.
I invoice via my own company. But this is not mandatory. You can also apply for a VAT number as an individual and follow the same procedure. I did this before I set up the company.
In EU since Jul'23 cross-border remote work is free of extra taxes and similar obligation if done up to 50% abroad. One can come to Germany for 3 days and come back to his country to work for 2 days remotely and spend weekend.
Unfortunately this is effectively useless as you need to submit your employees one by one to get this exception. I know of an employer ($4bn revenue) who said this is simply not feasible.
Real historical data might not cover current market state.
For example, option price among other params depends on the interest rate. For the last decade interest rate was around 0% in Europe and slightly higher in US. If you train on that data only, there is no chance to "learn" option prices in the high-interest-rate environment which we saw for the last few years. Hence, you need synthetic data to learn that region of the market space.
You don't need fancy math to study financial modeling, like measure theory. Focus on market dynamic, like in physics try to model that with math and programming. Newton built solid models without advanced math of XX or XIX centuries. Of course, some advanced effects require advanced math, but those are built on top of simple theories, like General Relativity on top of the Newton theory.
Maybe it’s the course I’m taking but a lot of the results are surprising to me.
> such and such is a martingale so this term goes to zero
This is why I dug into stochastic calculus and from there to measure theory, because it seems even the rigorous treatment of Brownian Motion springs out of Kolmogorov’s extension theorem… and every section I’ve read on optimal stopping is over my head rn.
As already mentioned American / European / Bermuda / Asian options vary by features of option contracts. They don't belong to a particular regulatory regime. For some reason its names are associated to the geo locations. I'm sure there are people who can wrap that in a nice narrative. :)
