Is it possible to download my account activity
yes, you can download your monthly activity in pdf format.
I was looking for a menu item but I see it appears on the timeline within the Activity tab at the end of each month.
That is a monthly statement showing your current holdings at that time, it’s not s report of your monthly activity as it does not show purchases, sales, top ups, withdrawals or dividends ,
You are right… a complete report would be so much better.
