Limit orders

[sktrader1]

Hi I am trying to place 2 limit orders (one buy, one sell) and control them differently. Also I would like to control the longs and the shorts differently (independent of each other like different trades with different parameters).
Now I have noticed the following which may be a bug. When I have the following code

EnterLongLimit(X[0], "L");
EnterShortLimit(Y[0], "S");

only one of the two works. Only the first one in particular. So if I comment the top one the orders I get are always short but if I leave them as above I get only long (!). Why is that?

Hello Sktrader1,

You are running into our internal order handling rules. Can read these at the bottom of this page.

The one that you're seeing is highlighted in bold below.


Methods that generate orders (excluding market orders) to enter a position will be ignored if:

• A position is open and an order submitted by an exit method (ExitLongLimit() for example) is active and the order is used to open a position in the opposite direction
• A position is open and an order submitted by a set method (SetStopLoss() for example) is active and the order is used to open a position in the opposite direction
• The strategy position is flat and an order submitted by an enter method (EnterLongLimit() for example) is active and the order is used to open a position in the opposite direction

With our upcoming version 7, we have introduced unmanaged orders which will allow both of these submitted at same time. Version 7 is in public beta and you can download it here.

See here for information on unmanaged orders in version 7.

I see. That is very limiting. I downloaded ninja7 but somehow when I apply the strategy to the chart it doesnt work. I will investigate further.

[NinjaTrader_RyanM1]

With version 7 there is an additional step needed once the strategy is applied to chart.

You must set Enabled to true: Either through the Right Click > Strategies screen from chart or the strategies tab of the control center.

Thanks that did work. So what am I looking at? Is it the unmanaged approach?

[NinjaTrader_RyanM1]

Yes, the unmanaged approach is needed if you would like to submit limit orders in both directions at the same time.

There will be different order submission methods for this approach. An introduction to this is found at this link.

I try the following

In the variables section:

private IOrder entryOrderL = null;
private IOrder entryOrderS = null;

and in the main



if (entryOrderL == null)
{
entryOrderL = SubmitOrder(0, OrderAction.Buy, OrderType.Limit, 1, X[0], 0, "", "Enter Long");
}

if (entryOrderS == null)
{
entryOrderS = SubmitOrder(0, OrderAction.SellShort, OrderType.Limit, 1, Y[0], 0, "", "Enter Short");
}

it seems to enter only the first short.
Nothing on the long side. Is there something obviously wrong?

Sktrader1,

Tested this over here on a real time basis and it submitted both orders. To test on Real Time only add if (Historical) return; to OnBarUpdate() method and set Minimum Bars required to 0.

You will likely need to reset your IOrder objects when orders are filled or canceled.
