iMA: What's the difference between shift and ma_shift??? - page 2

 
phy:

Shift is which bar the calculation is being performed upon. You should generally perfrom the calculation for each bar at least once.

ma_shift moves the resulting line into the future or the past, imagine grabbing the MA line on the chart and moving it left or right.

Perhaps the best way to find out the difference between ma-shift and shift is the scenario of these two params, why should we use the two params?According to phy: what is the meaning of grabbing the MA line on the chart and moving it left or right? many thanks for your prompt reply.
