Do not think I have lost money due to the bug, since it normally only
affects what happens with a number of bars. But it might make it harder to
find working patterns since DMI (amongst others) comes out different
compared to what it should become.

I did not understand plot2 being lower than plot1 in TS PRO. Plot1 is fixed,
so it is as I expected the same bug in TS PRO if plot1 plots the same on
both of them. 

But plot2, how can it differ? The part included does not contain any
accumulator, that comes later in the original code. Could it be that you are
looking at different dates or got different scales? The plot2 value is just
a difference between highs (mainly) and should return the same values in
both versions.
