Hello ClauTrade, and thank you for your questions. While we may only answer questions about how Ninja operates, and while direct development and debugging are outside of the scope of the support we may provide, I may answer some of the questions you have. Should you require more in depth development and debugging help, please let us know so we can help put you in touch with a NinjaScript consultant.

With respect to the 9.99... x 10^-5 numbers, and the 0.0001 + ε numbers, you can filter and convert these to 0.0001 with this code :

Code:

[FONT=Courier New]// publicly available C# documentation
// https://msdn.microsoft.com/en-us/library/system.math.round.aspx
Print("... | DIFF. PRICE = " + Math.Round(entryOrderBuy.StopPrice - GetCurrentAsk(), 4));[/FONT]

To your second question, the 2nd argument to Math.Round is the number of decimal places to round to. You can pass 0 in here if you would like whole numbers.

To your third question, the trade desk makes the decision whether to PartFill an order or not, and for this reason I would recommend handling this state in OnExecution (NT8 OnExecutionUpdate) rather than OnOrderUpdate. This state is not related to whether an order away from the price is active. I recommend printing out your order states for debugging purposes. I also recommend reviewing the order state definitions here.

NT7 : http://ninjatrader.com/support/helpG...nt7/iorder.htm
NT8 : http://ninjatrader.com/support/helpG...n-us/order.htm

Orders away from the current price are usually in the Working state.

Please let us know if there are any other ways we can help.

Many Thanks Jessica, great exhaustive answers!

So, I confirm the code to convert/filter work fine, this is the new code:

Code:

protected override void OnExecution(IExecution execution)
        {
            
            
            if (entryOrderBuy != null && entryOrderBuy == execution.Order)  
            {
                if (execution.Order.OrderState == OrderState.Filled)
                 Print (Time[0].ToString() +"| LongStopOrder = " +  entryOrderBuy.StopPrice + " | ASK PRICE = " + GetCurrentAsk()+ " | DIFF.  PRICE = " + Math.Round(entryOrderBuy.StopPrice - GetCurrentAsk(), 4));
                
             }
            
            if (entryOrderSell != null && entryOrderSell == execution.Order)  
            {
                if (execution.Order.OrderState == OrderState.Filled)
                 Print (Time[0].ToString() +"| ShortStopOrder = " +  entryOrderSell.StopPrice + " | BID PRICE = " + GetCurrentBid()+ " |  DIFF. PRICE = " + Math.Round(GetCurrentBid()- entryOrderSell.StopPrice,  4) );
            }

This is the simply code in OnBarUpdate() to close the trades by strategy:

Code:

    
    //     EXIT BY STRATEGY
            
            if (Position.MarketPosition == MarketPosition.Long && TradeExit == 1)
            {
                    entryOrderBuy = ExitLong("buy order");
                    entryOrderBuy     = null;                        
            }
            
            if (Position.MarketPosition == MarketPosition.Short && TradeExit == -1)
            {
                    entryOrderBuy = ExitShort("sell order");
                    entryOrderSell     = null;                        
            }

I believe what is occurring is that the order is being closed with a market order. To know for certain what is happening, you may want to simply

Print(execution.order.ToString())

This will let you know exactly what kind of order is being processed, all of its price values, and many more things about this order.

If you could add this into your code, and then run it over the same time period in the Market Replay connection, if you then see any more unusual output please don't hesitate to reach out so we may assist further.
