all you ahve to do is insert the values you want into the basic slope equation
example for a certain bar, or between 2 bars
Curve = MA(C,10);
slope = (Y2-Y1)/(X2-X1) = ( Valuewhen(barindex()==124,Curve) -
Valuewhen(barindex()==123,Curve) ) / ( 124 - 123 );
"calculate the value of a specific point on the MA, not the actual
close price of the stock at the corresponding time (i.e., close
price per bar)."
