Is this what you are looking for ?

RateOfChange = ( ( C-ref(C,-1) )/ref(C,-1) )  - ( ( ref(C,-1) - ref(C,-2) )
/ref(C,-2) );

Subject: [amibroker] rate of change/acceleration


I am trying to find a way to find out whether, and how much, a chart 
has accelerted over the previous period. This is not ROC, but more 
true 'rate of change' in a differential calculus sense. 

IN other words - if diff between close today snd  close yesterday > 
close yesterday and the day before, then the close prices are 
ACCELERATING up over the last 3 days.

Can anyone think up a general way to code this?
