I'm currently deciding which backtester to use for testing stragies on trading cryptocurrencies.
So far, I like backtrader a lot, but I still got one question.
One of the characteristics of cryptocurrencies is, that one can buy only a fraction of a coin. With a relatively low capital,
buying partial coins is very interesting.
How can i accomplish that with backtrader? Do I have to write a sizer for this or does one already exist?
