Why can't I see the signal's trade that I copied in my 'Activity' page?

The activities page will show a copier the trades of the signals they are copying/following.

It will show the trades a signal has made in the past or trades they currently have open. However, the trades will appear in the time zone of the signal so may appear different to a copy trade.

The number of trades shown is dependent on the signals trading volume; high volume signals won't always have all their trades appear on your activity page.
