SmartQuant Discussion

Hi I am getting some strange results from my system so wrote a test system to find out the problem. Think I have isolated it can anyone explain how this it is possible to get an exit target order or stop order filled before the entry order when using OnOrderFilled:

using System.Drawing;

using OpenQuant.API;
using OpenQuant.API.Indicators;
using Indicators;
using Portfolio;

public class MyStrategy : Strategy
{

[Parameter("Quantity", "Strategy Parameters")]
double quantity;

Order targetOrder, stopOrder;

SMA sma;

public override void OnStrategyStart()
{
sma = new SMA(Bars, 10, Color.Green);
Draw(sma, 0);
}

public override void OnBar(Bar bar)
{
if (sma.Contains(bar.DateTime) && sma.Count>1)
{
if(!(HasPosition))
{
if (sma.CrossesBelow(Bars, bar, BarData.Close))
{
Buy(quantity, "Buy Entry");
}

if (sma.CrossesAbove(Bars, bar, BarData.Close))
{
Sell(quantity, "Sell Entry");
}
}
}
}

public override void OnOrderFilled(Order order)
{
//Cancel Position
if (order.Type == OrderType.Stop)
{
CancelExitOrders();
}
if (order.Type == OrderType.Limit)
{
CancelExitOrders();
}

//Target and Stop

if(order.Text == "Buy Entry")
{
targetOrder = SellLimitOrder(order.Qty, 10 + order.Price, "Target Sell");
stopOrder = SellStopOrder(order.Qty, order.Price - 10, "Stop Sell");
targetOrder.Send();
stopOrder.Send();
}
if (order.Text == "Sell Entry")
{
targetOrder = BuyLimitOrder(order.Qty, order.Price - 10, "Target Buy");
stopOrder = BuyStopOrder(order.Qty, 10 + order.Price, "Stop Buy");
targetOrder.Send();
stopOrder.Send();
}
}

private void CancelExitOrders()
{
if(!(targetOrder.IsFilled || targetOrder.IsCancelled))
{
targetOrder.Cancel();
}
if (!(stopOrder.IsFilled || stopOrder.IsCancelled))
{
stopOrder.Cancel();
}
}
}

Here are the results for this code based on QQQQ 5 min: This shouldn't be possible because an entry order has to be filled first. Also this system should only use OnOrderFilled so that we can be certain that the order has traded.

Thanks.

Solved use AvgPrice for the fill

Good to hear you've solved it yourself!
