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=3This 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
