/* 
Twiggs Money Flow is a derivation of Chaikin Money Flow indicator, which is in
turn derived from the Accumulation Distribution line. 
However, Twiggs Money Flow makes two basic improvements to the Chaikin Money
Flow formula:
1-To solve the problem with gaps, Twiggs Money Flow uses true range, rather
than daily Highs minus Lows.  
2-And, rather than a simple-moving-average-type formula, Twiggs Money Flow
applies exponential smoothing, using the method employed by Welles Wilder for
many of his indicators.
