Now, I think the question you are also asking is why the % holding for the 8th is 0%? Which is why your previous value on the 9th is showing as 0% and not the value from the 7th. The reason it is showing as 0% is because, taking the Shin-Etsu Chemical Co Ltd holding as the example, you have uploaded a positions file on the 8th which does not contain this asset but your uploads on the 7th and 9th do. Rapptr takes this as though you have sold out of the position and hence have a holding of 0%. If you upload the asset on the 8th as well, this 0% will update to the correct value (assuming you had not sold out the position then). I have noticed this dropping to 0% has happened frequently in the result history for Shin-Etsu Chemical Co Ltd, so I suspect all are for the same reason.
