the history shows other movements witch you need to look into

i would explain whats with the compares

if this was the only movement in date then it would be a flat price and not a range

I can't make heads nor tails from any of the trades in this history

There seem to be gaps and the time the item (dis)appears does not match with the history entries in many cases.

The only other exchanges in your history are tradebacks, so this is the only sale.

Searing crones (125) + 30 = 155. You can resuggest at 155 flat.

Closing, feel free to resuggest according to my previous comment.
