While the google download script now indeed no longer causes a crash, there is a large discrepancy in the test results of the Z8 system with the google data. The drawdown is more substantial (The previous test was made with the 1.58.0 beta version, whose result I fortunately still had in the log directory), AR was about 18% with leverage 2 and now it is down to 13%. Is googles data adjusted for dividends, splits etc.?
