When I run https://mtgox.com/api/1/BTCGBP/public/trades?since={trade_id}, I get the latest 500 trades since that {trade_id}.
Now I have for example these two trades returned:
Code:
Trade #1
{"date":1342135345,"price":"4.77728","amount":"5107.98029213","price_int":"477728","amount_int":"510798029213","tid":"1342135345801755","price_currency":"GBP","item":"BTC","trade_type":"bid","primary":"Y","properties":"market,mixed_currency"},
Trade #2
{"date":1342136454,"price":"4.78","amount":"0.02000488","price_int":"478000","amount_int":"2000488","tid":"1342136454726203","price_currency":"GBP","item":"BTC","trade_type":"bid","primary":"N","properties":"limit,mixed_currency"},
Note the different properties: "market,mixed_currency" & "limit,mixed_currency".
What is the difference between a market and a limit property? What do both mean? (I couldn't find it here https://en.bitcoin.it/wiki/MtGox/API/HTTP/v1)
And also: what does it mean for a trade to be mixed_currency?
