Answered all of my own questions, if anyone needs the info

If you trade and then tt forward it completed your item instantly

Yes, you can go back over dates the same day (ie; 4th, 5th, 6th, repeat repeat etc)

If I go forward by weeks sometimes I can get the sparkle, it’s hit or miss but worth a try.

Hope this helps.
