If I have financial data with prices as the first column and I create an array of integers from 1 to the length of data to use as a time axis am I correct in calculating deltaT
Which gives me a new array of singles. How would I then proceed to calculate specific values of ∆t such as ∆t=1 and is it possible to relate this to prices in that. I wish to plot d1(t) in that.
for x prices
