I had the same problem and Tomasz told me to add
SetBarsRequired(100000,100000);
to the top of the code. Apparently the charts do not use all the
data while explore does, therefore a difference in results. The
above function will force charts to use all the data and the results
should then be the same. See if adding that to the code fixes your
problem.
