Price ticks are now internally stored in a different format that used less memory for large high-resolution backtests, but reduces the test accuracy by discarding the open and close prices of a tick (only high and low are stored). Set the EXTRADATA flag for storing also the open and close prices. (V 1.47.7).

Yes - this is the reason for the difference between both versions (at least concerning this script). That means from now on we have to set the flag EXTRADATA always to receive results as accurate as in former versions?
