Overview
Historic price data are fetched daily via the Marketstack and CryptoCompare APIs, and converted to CSV format using Python; each currency pair is then analysed in C++. Finally, the table below is generated using the trade summary.
Profiling
The C++ code is profiled using gprof and visualised with gprof2dot and graphviz.
