Adding to position

[nysetrader]

How can I add to existing position to manage them as one position?
For example I bought 100 shares at 30$, then I bought 100 shares at 31, so I have a position 200 shares with average price 30.50$. But all I tried in NT creates second position so I have 2 positions at 30$ and 31$ 100 shares each and I can manage them separately, but I need to manage them as one position.

Hello nysetrader,
You can use the Position class to do it.

Position.AvgPosition will return the average entry price and the Position.Quantity will return the total quantity of the strategy.

Please refer here to know more about it

Please let me know if I can assist you any further.

I did it, but when I use SetTrailStop it closes only last position I have.

Hello nysetrader,
To assists you further may I know, have you assigned unique names to your orders?

What are the exact Entry and the Set() codes.

I look forward to assisting you further.

        protected override void OnBarUpdate()
        {
			if ((Bars.GetDayBar(1) == null))
			{
				return;
			}
			Quantity = 100;
			if(Position.MarketPosition == MarketPosition.Flat)
			{
				if (CrossAbove(Close, CorrelationSPY(deviation).UpLine, 1))
				{
					EnterLong(Quantity, Instruments[BarsInProgress].FullName + " long");
					SetStopLoss(Instruments[BarsInProgress].FullName + " long", CalculationMode.Percent, StopLoss, false);
				}

				if (CrossBelow(Close, CorrelationSPY(deviation).DownLine, 1))
				{
					EnterShort(Quantity, Instruments[BarsInProgress].FullName + " short");
					SetStopLoss(Instruments[BarsInProgress].FullName + " short", CalculationMode.Percent, StopLoss, false);
				}
			}
			else
			{
				if(BarsSinceEntry()>5)
				{
					if(Position.MarketPosition == MarketPosition.Long)
					{
						if(CrossAbove(Close,Position.AvgPrice*(1+0.01*Position.Quantity/Quantity),1))
						{
							EnterLong(Quantity, Instruments[BarsInProgress].FullName + " long");
						}
						SetTrailStop(Instruments[BarsInProgress].FullName + " long",CalculationMode.Ticks,	(int)((MAX(High,BarsSinceEntry())[0]-Position.AvgPrice)*0.3), false);

					}
					if(Position.MarketPosition == MarketPosition.Short)
					{
						if(CrossAbove(Close,Position.AvgPrice*(1-0.01*Position.Quantity/Quantity),1))
						{
							EnterShort(Quantity, Instruments[BarsInProgress].FullName + " short");
						}
						SetTrailStop(Instruments[BarsInProgress].FullName + " short",CalculationMode.Ticks,(int)((Position.AvgPrice - MIN(Low,BarsSinceEntry())[0])*0.3), false);
					}
				}
			}
        }

The idea is to add to position every 1% of move and to exit at 30% trail stop on the whole position. So I count how many ticks was MAX profit and set stoploss to 30% of its value.

Hello nysetrader,
If the strategy is a multi-timeframe strategy (and not multi-instrument strategy) then the order names for the 2 entry are the same. The internal order handling rules will reject the order (unless Entry per direction is set to 2 or more).

Also you cannot use the SetStopLoss and SetTrialStop in the same strategy unless unique names are assigned to each orders.

Please make sure you assign unique names to the orders and check if it works or not.

Please let me know if I can assist you any further.

Entry per direction is set to 30. How should I code adding to position?
The first entry is made by simple condition, then I'm adding to position every 1% of move. As I understand you I cannot use same ID for orders when I'm doing adding. How should I code SetTrailStop for the whole position? without any ID? Can you make a sample for it?

[NinjaTrader_Joydeep]

Hello nysetrader,
Yes, do not assign any names to the entry orders and just set the SetTrialStop code in the Initialized section of the code.

Unfortunately we do not have any sample codes on this line.

Please let me know if I can assist you any further.

[nysetrader]

SetTrailStop in Initialize section is not suitable, because I need to use it only after adding to position. I've tried entries without any names, and it closes only last position, not the whole.

Hello,

You have you use either SetTrailStop or SetStopLoss in a strategy you cannot use both.

In the case that you needed auto trail be did not want SetTrailStop or wanted a more advanced auto trail then what SetStopLoss delivars you would need to program the stop loss move up yourself.

Please see this guide here that should help show you how you would do this in your strategy.
