Sorry if this question is noobish. I thought I had the maker/taker fee mechanism figured out (already existing question at Maker taker fees - can somebody explain in plain english?); apparently I was wrong. Yesterday I put an order to sell LTC at EUR 45 on Kraken, while the market was still at about EUR 44.27. Today my order was filled. However, I was charged the taker fee instead of the maker fee for this transaction.
Why is that the case? I thought for a transaction to be charged the maker fee, the selling order only has to be higher than any of the buying orders that existed at that time? When I put out my order, wasn't it higher than all the buying orders on the market?
Is it because somebody before me already posted a selling order at EUR 45 and I was only adding volume to that already existing selling price, so I was charged the taker fee?
Or is it because when my order was finally filled, the most recent market price actually went above (bypassed) EUR 45, and then went down again?
EDIT: Actually somebodyI got the following response from Kraken replied to me on Redditbut I'm still confused:
Without selecting "Post Only Limit," the order will fill at your Limit as either a Maker or Taker order. The Limit is the only condition that was set. Even if you set the order hours ahead of time, other orders can exist on the order book that would predate your own. Especially at round numbers, like 45.00. You could try 44.99, and might have better luck.
I thought that I would only have the taker fee applied if there were already buying orders at the same price, and asked me to openthen I placed a ticketselling order, thus “taking away” the already existing buying order. I did it and would waitHowever, this response seems to see what they sayimply that the taker fee would also apply if there were previous selling orders at the same price when I placed my order. Does that make sense?
