well, as they say - there's never anough speed...
Linux, could it be - if "SMI" in SMI Ergodic - "Sto Momentum Index", than our Ergodic - osma of Stochastic (SMI)? hmm
ergo tsi = osma tsi
TSI = ds mom/ds abs mom
sto: (cl-ll)/(hh-ll); ds, (hh+ll)/2 etc - what it has to do with momentum? could it be they made mistake?
