Nodes.wavesplatform.com questions about transactions


#1

When looking at a transaction like:
https://nodes.wavesplatform.com/transactions/info/2QkyD2ga7XMtjSZbHzLt8qg3SwwrhDu5ecwcEuTArnRL

There is an amount and price for the transaction then also a buy and sell section with their own amounts and prices. I am struggling with understanding this. In this case those 2 amounts don’t relate to the total on the transaction which is also the amount that shows on the waves platform/wavesdex.

From this api result, how does one tell if the transaction was bought against a sell wall or sold against a buy wall?

I appreciate any help that you can provide in helping me understand this better.

Here is the data from the link above:
