Different amount in operation and its effects

Question

I have a manage_offer operation (https://horizon.stellar.org/operations/70271497528152065) on the Stellar live network. It has amount=5.8869963 and price=0.4689155, so from the other side amount should be amount*(1/price)=12.55449286705174. This transaction has one effect (successful trade, https://horizon.stellar.org/operations/70271497528152065/effects) which has sold_amount=12.2645807 and it doesn't match.

Am I missing something?

Answer 1

I figured out that I had set a wrong price. Actually, it should have been 1/price=2.13258039028. Due to this mistake best matching order was completed.
