There is an actual solution - full memory encryption on recent Intel/AMD CPUs.

The default is an unencrypted computer. Microsoft is trying to improve that default without requiring yet another password.

European fridges also have a freezer, while remaining single door. Top half fridge, bottom half freezer.

I wonder if EU fridges are smaller because people buy food more frequently, but in smaller quantities. Because the grocery shops are closer.

Fast memory is very expensive.

Which is why you only use it when you really need it - on a GPU/AI accelerator.

And Microsoft/Apple/Facebook sells stuff in Europe through a company incorporated in Ireland. Does that make those companies Irish?

Algotrading has two parts - analyzing data to find strategies and executing the strategies.

Numba is for the first part, where you might need to process billions of messages to extract signals.

Sometimes you just need a plain old "for" over your pandas dataframe, to do a more complicated aggregation (variable window size, conditionals, ...)

You can try twisting numpy/pandas into a solution, but it might be much simpler to just write a dumb numba function which will be easier to maintain since the logic will be very clear.
