Combination Charttrader and Ninja-script stops

[TheChingachgook]

Today I attended the chart trader seminar and there I didn't really get an answer about the following question:

I would like to perform semi-automated trades...

that means, I would like to enter (open) trades via the chart trader but the stop should going to be a self-coded Ninja-Script stop strategy.

In the webinar I was told, when I want to use Ninja-script I have to switch off the chart trader!!!??

so... is it anyhow possible to perform a combination of manual entered trades and self-coded stops?

many thanks for your help

>> but the stop should going to be a self-coded Ninja-Script stop strategy
Unfortunately this is not supported, since a NS strategy only can manage order/position triggered/entered by itself.

ooops.... does that mean, that it is also not possible to use ... for example ... an indicator like a Parabolic SAR, or a Bollinger band or what ever as a trailing stop when the charttrader is activated??

Sorry, I'm confused. Is this about indicators (no problem there) or about NinjaScript strategies where you can not exit a position entered manually e.g. by chart trader?

What I want to achieve, that after I get a signal based on a certain chart constellation, I want to manually place an order (stop- or market ) into the chart.

As soon as the order gets filled, the system - in form of an indicator, strategy or what ever - should take control about the trade.

So if you can show me the way how I can use - in combination with the chart trader - an indicator (common or self coded) as a automated stop-strategy, I would be absolutely happy.

many thanks for your help

Indicators can't manage orders/positions only strategies can -> unfortunately what you wanted to achieve is not supported

Dierk,

If a position is opened manually by an ATM order, can't a strategy be created with utilizes the GetAtmStrategyMarketPosition() function, and then use some logic from within to close such an order?

Dierk,

This is not possible since you need to have a id reference to the ATM strategy. You can only provide a id reference by programatically spawning an ATM strategy.

OK ... I think I have to accept, that it is not possible to combine the chart trader with Ninja-Script strategies....

let's try with a fully automated system ....

... is it on the other hand possible to press all my signals into a strategy and whenever a signal occurs I get decision-popup (yes-no decision) where I can decide to perform the order or not

Order confirmation for strategies are currently not supported.

If you're using MBT then yes, you can finagle it a littl bit.

You can set the MBT confirmation quantity threshold below however many lots your order consists of, this way the MBT order confirmation window comes up and to confirm that you want to allow the order to be processed.

OK guys ... here I found a solution to confirm orders in a Ninja Script strategy:

quantity = orderHandler.GetQuantity(Instrument);

....
....
using System.Windows.Forms;
......
......


if ( positionCounter != 0)
quantity = (int)Math.Round(quantity / (double)Math.Abs (positionCounter), 0, MidpointRounding.AwayFromZero);
int isLong = (int)myBollBandReversal.GetIsLong();


direction = isLong == 1 ? "Long" : "Short";


DialogResult dialogResult = MessageBox.Show(Instrument.FullName + ": " + strategyName + direction + "-Order ausführen?", "Achtung", MessageBoxButtons.YesNo, MessageBoxIcon.Question);

if ( dialogResult == DialogResult.Yes ){

if ( isLong == 1 ) {
pendingOrder = OpenLongOrder(quantity, entryPrice, pendingOrder, strategyName);



that means, whenever I get a signal, a messagebox appears, where I can select wheter I want to perform the order or not.

... as easy as that ...

Well, it's not that simple (and that's why it's not supported). Here are some hints (but not getting into deeper discussions on windows concepts):
- a modal dialog will block your app. Not sure if you could afford that
- NT7 will come with multi-threading on NinjaScript objects. It no longer is guaranteed that your code would be executed in the app's main thread -> any UI related code could fail and even crash the app (see windows API docs for details)
