COMPUTING THE CURRENCY CONVERSION FACTORS

  Computing the "currency" conversion factors to apply to the USD,CNY volumes before combining all 
  prices into a single mean price.
  
    rundate="2015-02-20" # Nominal date of experiment.
    make_and_plot_currency_factor_file.sh "${rundate}"
    
  To compute the average CNY:USD exchxange rate, pipe the 
  relevant segment of the file out/2014-11-29-01d-gox-full-ccf.txt 
  through the script
  
    gawk \ 
      ' /^20/ { 
          ccf = $14; 
          if (ccf > 0.0) { y = log(ccf); swy += y; sw += 1; }
          next;
        }
        END { 
          printf "%8.4f\n", exp(swy/sw);
        }
      '
    
TO DO:

  Combine the daily prices, unsmoothed, using the currency conversion factors obtained above.
  Is it necessary to ignore the small bumps and dips in the factors, that are due
  to China being ahead to the West during the 2013-04 and 2013-11 bubbles?  Maybe not.
  Using those variable factors will give more weight to the Western prices, which seems
  OK.
