XChange java Poloniex: Hot to set price for Limit Order

Question

I cannot figure out how to set the selling/buying price for my limit order for Poloniex Exchange using XChange java library.

Bellow is initialization and my method for placing Bids but there is not price for setting.

ExchangeSpecification exSpec = new ExchangeSpecification(PoloniexExchange.class);
exSpec.setApiKey(POLONIEX_API_KEY_PROP_NAME);
exSpec.setSecretKey(POLONIEX_API_SECRET_PROP_NAME);
Exchange poloniex = ExchangeFactory.INSTANCE.createExchange(exSpec);

//-- TRADE SERVICE.
TradeService tradeService = poloniex.getTradeService();

MarketDataService marketDataService = poloniex.getMarketDataService();
Ticker ticker = marketDataService.getTicker(CURRENCY_PAIR);

~

private static String placeBuyLimitOrder(TradeService tradeService) throws Exception {

    LimitOrder order = new LimitOrder(OrderType.BID, MAIN_IN_TRADE.divide(oldBid, 8, RoundingMode.HALF_UP).setScale(8), CURRENCY_PAIR, null, null, oldBid.subtract(Utils.SATOSHI));
    order.setOrderFlags(null);

    String orderId = tradeService.placeLimitOrder(order);

    return orderId;
}

This way sets my bid price equal to the highest bid in auction, but i would like to set i even higher. Does anyone know hot to set bid/ask price by myself?

Thanks.

Change:

LimitOrder order = new LimitOrder(OrderType.BID, MAIN_IN_TRADE.divide(oldBid, 8, RoundingMode.HALF_UP).setScale(8), CURRENCY_PAIR, null, null, oldBid.subtract(Utils.SATOSHI));

to :

LimitOrder order = new LimitOrder(OrderType.BID, MAIN_IN_TRADE.divide(oldBid + 0.005, 8, RoundingMode.HALF_UP).setScale(8), CURRENCY_PAIR, null, null, oldBid.subtract(Utils.SATOSHI));

if you want 0.005 higher
