Could anybody please send/write the following indicator:
Stochastic Momentum Indicator (Index).

I have been able to find its formula only for metastock
Stochastic Momentum Indicator

100 * ( Mov( Mov(C - (.5 * ( HHV(H,13) + LLV(L,13))),25,E),2,E)/
(.5*Mov(Mov( HHV(H,13) - LLV(L,13),25,E),2,E)))

Any help appreciated. Thank you.
