Topic: Cryptsy Ticker API with Bid/Ask Price? (Read 1022 times)
It looks like the asks and bids are ordered already. Together they make up the order book, all of which are unfilled. To get the market price, you could just take the latest order.
I'm trying to figure out the best way to implement a ticker using the Cryptsy API. I specifically want bid/ask prices and volume if possible.
The nearest thing I can find is this which retrieves market data (for LTC-BTC in this case)...
http://pubapi.cryptsy.com/api.php?method=singlemarketdata&marketid=3
This gives me a whole ream of stuff (below). But buried in there are "buyorders" and "sellorders". Am I correct in thinking that I must extra maximum/minimum prices myself to arrive at bid and ask prices here?
Is there a simpler way to do this?
Cheers
