For sometime I am using this java API http://xeiam.com/xchange/ for building bitcoin trading robots. Today I got a bit stuck and I wanted to see if somebody had the same issue before.

I call the order books like this:

OrderBook orderBook = exchangeMarket.getExchange().getPollingMarketDataService().
                                getOrderBook(CurrencyPair.LTC_BTC, new int[] {20});

My problem is that the orderBook object contains 100 asks and 100 bids. I just want 20. Does anybody know why this is not returning the amount I pass in the second parameter? BTW, if I try 150, it also returns 100. I don't know how to modify the amount of returned elements.

  • The xchange docs say that the meaning of getOrderBook's second argument is exchange-specific. Does the exchange you're polling support limits? Do they support them in the manner that you're using them?

  • @Nick ODell I am interested in the exchanges Cryptsy and BTCE, but I am not sure how to find if they support limits. Also if they do support, how do I pass the parameter? I tried different things like new Integer[]{20,20}... but nothing worked, I would like to confirm that indeed there is no such support in those exchanges.
