Have there been any independent tests to validate the Quantopian backtester and compare its results to those obtained by other platforms, such as Tradestation for example? With all respect I'm asking because I would not like to invest time, which means money, to learn something and later discover that there were some bugs in the backtester and my results were not correct.
Maybe this question: Who developed the Quantopian backtester algorithm? Is it part of TA-lib? Has TA-Lib been validated?
