Please, take a look at the attached screenshots below. There is something wrong when plotting the same data (AEXGR.AS) in two different accounts. It results in different percentages at the end of the time period. Notice the yellow markings…
I’m sure it’s a bug, also in fullscreen.
I’ve made two screenshots with the real values (click on it for enlargement), it only occurs with this index as you can see (29,72% vs. 27,7% same dataset, starting on 2nd of August)…
I estimate that you’ve choose Yahoo Finance as source to get historic and last price information
If so I assume that the quoted price in both files are slightly different, because as Yahoo provide the latest price without historical prices it’seems possible that you do not have the same information synchronised in both accounts due to different time slots. Did you have compared both files?
No, that’s also not the reason, AEX GR is also not fluctuating that much ;).
I solved the problem by adding the value for AEX GR at the start of the selected period (in this case 2019). I think there was a floating reference. Now, it’s strictly defined and the percentage is displayed well on both accounts. Thank you all for the given input.
