Hi PotHead,
No Standard Deviation is NOT the same as Mean Deviation, although with the correct numbers they would come out the same. The STD would never be a negative number, whereas the MD could be a negative value.
This might help a bit:

And yes, i can't find an STD function either - weird that it doesn't have it. So alas you are probably stuck doing it the hard way by doing the calc yourself. Having said that, I don't recall seeing a square-root function either so if that is missing you would be SOL.

Hi RandallSell ,
Thank you for the comment. It seems I cant calculate standard deviation in jstock. Jstock editor lacks many math function like square root, log, exponential etc. Now i have to find another way :(
Once more thanks man for the quick info 💯
