I can't place limit order!

I have the following code:

var tradeResult = PlaceLimitOrder(nextTradeType, Symbol, nextTradeAmount, nextTargetPrice, PositionLabel, nextStopLossPips, nextTakeProfitPips);

var PositionLabel = "testLabel";
var nextTradeAmount = 1000l;
var nextTargetPrice = 1.12897d;
var nextStopLossPips = 10d;
var nextTakeProfitPips = 10d;
var nextTradeType = TradeType.Buy;

var tradeResult = PlaceLimitOrder(nextTradeType, Symbol, nextTradeAmount, nextTargetPrice, PositionLabel, nextStopLossPips, nextTakeProfitPips);

            if (tradeResult.IsSuccessful)
                Print(
                    string.Format(
                        "Placed limit order. Volume: {0} | Symbol: {1} | Trade type: {2} | Target price: {3} | Stop loss: {4} | Take profit: {5}",
                        tradeResult.PendingOrder.Volume, tradeResult.PendingOrder.SymbolCode,
                        tradeResult.PendingOrder.TradeType,
                        tradeResult.PendingOrder.TargetPrice, tradeResult.PendingOrder.StopLoss,
                        tradeResult.PendingOrder.TakeProfit));
            else
                Print("Error placing limit order: " + tradeResult.Error);

The result the the following:

I start a backtest on 26/08/2016 and the order is filled directly, even though the price is wrong!

What is happening?!
