In there, I corrected two minor errors, and added a calculation and representation of the standard deviation of the estimation of the box-counting dimension. The two minor errors were the following:

– At line 199:
Instead of : for( iteration=0; iteration < g_period_minus_1; iteration++ )
It should be : for( iteration=0; iteration <= g_period_minus_1; iteration++ )

– At line 213:
Instead of : fdi=1.0 +(MathLog( length)+ LOG_2 )/MathLog( 2 * e_period );
It should be : fdi=1.0 +(MathLog( length)+ LOG_2 )/MathLog( 2 * g_period_minus_1);

Here is what it looks like on a daily chart for EUR/USD, the lower window represents the original fractal dimension by iliko, and the moving average is the FRASMA I published earlier:
