I have noticed that the Force Index on TC 2000 version 12.6 does not allow me to choose to make it an exponential indicator whereas on Stock Finder 4 it does.  I like to use a exponential Foce Index of 13.  Can you give me the formula for this so that I can make a exponential Force Index indicator on TC 2000? 

Happy New Year and thank you for your help. 

The Force Index uses exponential averaging in TC2000.  In StockFinder you could use different averaging methods but in TC2000 it only uses exponential as designed by Dr. Elder.

In SF I am using an EMA of the Force Index 13 and I am uisng Force Index 13 in TC2000.  Using the SPY daily chart the closing number in SF is -307.8568.   The figure for TC2000 is - 48.5.  Why the difference? 

Set the Force Index to 1 and the exp moving average of the force index to 13.

"a 13-Period Force Index is a 13-period EMA of the 1-period Force Index values for the last 13 periods"

ON both SF and TC2000 I am just using the index itself.  My settings on TC 2000 are smoothing 13.  That is the only setting.  On SF average type is exponential, and the moving average type is 13.  I do not use an extra moving average on the index.  However if I put the Force Index on 1 and then add an exponential moving average of 13, the two figures still are not same on SF and TC2K.  Somehow SF calculates the index differently. 

StockFinder reports volume in blocks of 100 shares while TC2000 v12/v16 reports volume using actual shares. This will affect the calculations as different volume will be used in each program.

Probably more importantly in that it makes it so you can't just move the decimal, StockFinder takes the square root of volume before multiplying it by the price change while TC2000 just multiplies the volume by the price change directly.
