Lets say you have 1mil of shares and the pps moves up and down by .001 that would means $1000 per tick. Now you have a R/S of 20/1 that makes out of your 1mil shares 50k. Now .001 X 20 is .02 (or two cents). 50k of shares x 0.02 is still $1000. If of course the ups and downs are by lets say 2 cents.....
