Is This Possible?

[yimbot]

I currently use a strategy that has discretionary entries (at least I can't imaging a way to code it...) but has purely mechanical exits based on indicators. As my exits have always been a weak point for me, I have found much greater success in using mechanical exits and stick to my entries which are quite good.
What I would like to build is a strategy that I can enter manually, but when I do, my position size is automatically calculated for me and entered and my exit is automatically taken care of also.
Does this sound like a pipe dream???

[yimbot]

Does anybody offer a coding service that could handle this type of thing??

[NinjaTrader_Ray]

No, this is not a dream however, this is not possible at the current time. This is on our list for future enhancement though.

Fantastic, can't wait!

If you know how to code your exits already, it is not that difficult to work around.

Instead of an automated entry, you could simply tell the strategy what position to start out at when you put it on the chart.

Let the strategy enter that position somewhere on historical data and it will simply perform a simulated entry, and from then on you can let it manage your real position.

Just take care to test what happens when you reload strategies on the chart. I always find this to be the time when most things potentially break, as a lot of internal variables get reset.

Thanks Gert74.
Sounds great, I could definitely work with that. I am not really sure how to set it up though, could you provide a little more info?

[NinjaTrader_JoshP]

I think what gert74 means is just have the strategy start up with an open strategy position that would match your manually entered position. The strategy would then proceed in all its calculations and exit the position whenever it deems necessary. When the strategy exits it will exit your real position too.

just have the strategy start up with an open strategy position

I'm interested in this as well, and was going to start a thread with the same question. I often enter positions manually and then would like the position "monitored" and exited when conditions are met.

What is a reasonable way to have the strategy start up with an open position that matches the actual account open position? Can the strategy be "seeded" with this information via user parameters? If not how can this be accomplished within NT?


Thanks,
Guy

This could be done however, there is not a simple approach. We would need to give this some thought on how a strategy could be coded and then deployed. Will add this to my list of reference samples. This will not happen in the short term.

Fundamentally, all you need are two parameters. One for the market position (using the built in MarketPosition enum data type will give you a nifty little dropdown) and quantity (your basic integer).

If you're a lazy programmer (like me), you could simply use a negative quantity for short positions, and then you would need only one parameter.

Now, your strategy will need to enter that position at some point before it can exit it again. What we want is for the strategy to enter the position somewhere on the historical part of the data series (so that it will be a simulated entry) and exit in realtime (to trigger a live order to the broker).

In theory you could enter at any point like the first bar of the chart. However, if you want you could add another parameter with a time or price point to enter at if you want to make it resemble your real entry for some reason.

That's the basic principle of it.

Just code your strategy to only look for your exit signal on realtime data, and you're good to go.

Thanks for all your feedback everyone, I appreciate the help.

I have had an attempt at creating a strategy, but it does not quite work as intended. Would anyone mind commenting on the code?

Perfect!! Thank you so much. I could have wasted days trying to figure that out...

[NinjaTrader_JoshP]

Great. Glad it worked out for you.

[yimbot]

Copied and modified the code for a short trade, but it does not exit the trade... any ideas?
