Using the definition of ROC in the Wiki,
"ROC(bar) = 100 * ( ( Pricebar / Pricebar - period ) - 1 )"

Is there a difference between

"ROC(Close,5)" and "100 * Close / (Cose >> 5) - 1" ?

If not, is there a strong reason to prefer one over the other? Which one?

Finally, is there a way to access a single bar value of ROC without creating a new data series?


TIA

Yes, the ROC.Value method.

There should be no difference and you can use any version but the correct version of your code would be:
