scaling out

I have a simple strategy:

Question 1:
When I go to strategy analyzer/charts, why do I sometimes see the occurence of 1 long(Long 1a), instead of the expected 2 longs as usual (Long 1a + Long 1b). I noticed it happens when system exits half the position. So looks like the system trigers 1 new long (Long 1a) after profit taking and returns to the allowed 2 longs (Long 1a + Long 1b).

Question 2:
In the code above, where do I add this code below to ensure that once the price is greater than entry price by 12%, I want to take profit by closing the Long 1a, and for the Long 1b set the stop loss to breakeven (level where I entered with both Long 1a and Long 1b)

protected override void OnBarUpdate()
{
            // Resets the stop loss to the original value when all positions are closed
            if (Position.MarketPosition == MarketPosition.Flat)
            {
                SetStopLoss("", CalculationMode.Percent, Stop_Loss, false);
            }
            
            // If a long position is open, allow for stop loss modification to breakeven
            else if (Position.MarketPosition == MarketPosition.Long)
            {
                // Once the price is greater than entry price by 12%, set stop loss to breakeven
                if (Close[0] > Position.AvgPrice * 1.12)
                {
                    SetStopLoss(CalculationMode.Price, Position.AvgPrice);
                }
            }
    
    // Condition set 1

Question 3:
Do I need all the conditions in this second code or just the one with if (Close[0] > Position.AvgPrice * 1.12)?

Question 4:
How do I set a different profit target (say 4%) ONLY for Long 1b?

Question5:
Finally, is the second code correct?, I mean would it do what I want it to do in question 2? I amended the code slightly, then went to the chart to check the result and could not see if it was actually working.


MANY THANKS

Hi ionaz, thanks for the post.

1. This likely happens as you're not entering only when you're in flat state for the strategy, so currently if your first target has filled and the condition occurs again, you would see a partial entry again.

2. The code for the stop adjustment would be in your OnBarUpdate() method as well. This is called on every bar, historical as well as realtime then.

3. You would need the reset condition as well, as noted in our example -

http://www.ninjatrader.com/support/forum/showthread.php?t=3222

4. You would add another call in Initialize() to a SetProfitTarget tied to signal Long1b that would be targetting your 4% exit then.

5. The code would only adjust the stop loss once your profit trigger is reached, it would not take any partial exit.

To know and understand what your code would be exatly doing, we would suggest working with Print statements, here's a tip that would explain this helpful deubbing technique deeper - http://www.ninjatrader.com/support/f...ead.php?t=3418

Thank you very much for your input Bertrand

Let me follow-up
1. So how do I code that I'm entering only when I'm in a flat state for the strategy? What's the code for that?

2. thx
3. thx
4. thx

5. So how to code to integrate all goals successfully:
i) take partial exit once the profit (12%) is reached,
ii) set profit target to 4% for Long 1B,
iii) exit Long 1B once 4% target is reached (after 12% was reached by Long 1a beforehand).

Thank you

ionaz, you can check the strategy position with the MarketPosition property -

http://www.ninjatrader.com/support/helpGuides/nt7/marketposition.htm

You would now need to combine the elements we discussed into your final script and let it then run with the EntryHandling set to .UniqueEntries :

Thanks Bertrand

Did everything as per your suggestion. I believe I did, compiled OK.

However, where it doesn't behave as expected is:
Long 1b closes before Long 1a (I can understand why - because its profit target comes first - 4% vs 12% for Long 1a).

As I said, I want it occur in exactly this sequence:
1) take partial exit once the target_1a (12%) is reached = exit Long_1a,
2) set stoploss to breakeven
3) exit Long 1B once 4% target is reached (after 12% was reached by Long 1a beforehand).

Please help!

ionaz, your NinjaScript / C# Code will always be logically processed and evaluate according to your set logic – this can of course lead to unexpected results at times, thus we would suggest to simplify and debug your code to better understand the event sequence it would go through - unfortunately we cannot offer such debug or code modification services here, but please see the provided resources below to help you proceed productively :

First of all you would want to use Print() statements to verify values are what you expect -

http://www.ninjatrader.com/support/forum/showthread.php?t=3418

For strategies add TraceOrders = true to your Initialize() method and you can then view valuable output related to strategy submitted orders through Tools > Output window - http://www.ninjatrader.com/support/f...ead.php?t=3627

It may also help to add drawing objects to your chart for signal and condition confirmation.

Also to consider: would the EntryHandling set allow multiple entries for your script?
