There seems to be something wrong with the Done Deals/Recent Transactions tab classification of trades.
Since every trade has both a seller and a buyer, the coloring of the trade as green/red (purchase/sale) and the inclusion of the corresponding buy/sell icon on the left column only makes sense if it is used to discern the market maker from the taker--that is, who 'made' an offer to buy/sell that waited in the system until the other person came and 'took' it.
Usually I observe that the coloring/icon is used to indicate the taker's operation (buy/sell).
That is, if I had a buy order standing, and someone came along and took it (created a matching opposite order and therefore sold stuff to me), I would observe that the line in the market history tab in the item's page (the Done Deals tab) would be red (and with a currency icon on the left).
That is, taker sells --> it's a "sell" line.
[red line]Conversely, if I had a sell order standing, and someone came and took it (and bought from me), I would see a green line with the basket icon in the done deals history.
That is, taker sells --> it's a "buy" line.
[green line]The above assumes the currency paper note icon (and red colored line) means 'sale,' and the basket icon (and green colored line) means 'purchase.'
What seems to be wrong is that, assuming the mechanism above, I should not observe things like this:
I did not initiate (that is, I was not the taker in) any of these trades. All were standing sell orders previously issued by me that were executed when people came along later and issued matching buy orders. In all those trades I was the seller and the market maker.
So, why the differing colors?
