Need some help debuging my first basic strategy

[dr0832]

I am a complete beginner to programming. I am trying to create a basic ATM strategy in Ninjatrader 7 using the new strategy wizard. For some reason I am getting and error
which I have included in a jpg screenshot, on the following line below once I view the code. Can anyone help me out?

if (CrossAbove(T3(MyInput0, 3, 0.7), T3(MyInput1, 3, 0.7), 1)

hello dr0832,

I just took a look at the code you posted and couldn't find anything wrong. To be sure I recreated the startegy in the strategywizard and I get no errors when I compile, your code is fine.

Having said that the error must be from something else, like another indicator or strategy that failed to compile.Can you re-post an image of the error with all the left-side colums visible ?

Thanks for taking a look. Here is the screenshot you requested.

[marcow]

Thank you,

The error is indeed in your strategy and not somewhere else.

However, as I mentioned before, I duplicated the code you posted into a strategy, and it worked fine on my computer. I attached this stratgey (qqq.cs) including all the required indicators. I suggest you import this strategy, so we are using the same code for further dubugging.

Don't know if you're familiar with importing code into NT, so here's a howto:
In the control panel, go to File/Utilities/Import NinjaScript and select the attached file (which of course you first downloaded to your computer) Do not unzip !
A popup window will come up asking if you would like to overwrite indicators.I suggest you overwrite at least the T3 indicator. No need overwriting the system indicators - the ones with "@".
You will now see the strategy in your list named as "qqq.cs"

let me know if it worked.

The strategy worked this time. Thank you for your help. Can you suggest any guides on learning Ninjatrader programming?

[marcow]

that's because there is an error in your strategy. (Or another one )
In NT all indicators/strategy's are "linked" so if there is only one indicator/strategy with erros, nothing will work.

To resolve this issue, go to the directory where the strategy's are located:
C:\Users\marco\Documents\NinjaTrader 7\bin\Custom\Strategy (replace marco with your own windows-username ) and find your strategy ( I believe it's called myfirtsstrategy.cs ,was it ?)
Now temporarily rename it to myfirtsstrategy.aaa

Now you should be able to import.

The key to learning NT programming imo is understanding why things didn't work

Does your original strategy work now, or are you using the one I created (qqq.cs) ?
If you undo the rename of your original strategy -see my previous post- do you get the error again when compiling, or is it fine now ?

I deleted my original strategy and then everything worked. Now the only problem is I just tried to run a backtest on the NASDAQ 100 using this strategy on historic data and when the backtest finished running it showed all of the 100 symbols but all the stats just say 0.00 0.00 0.00 1.00 .000% etc. Why would this be?

Can you undelete your original strategy and check if it now also works, otherwise we will never know what was wrong ?
Are there any differences in code between your original strategy and the one I posted ? Can you post your original strategy so I can take a look at it ?

Now the only problem is I just tried to run a backtest on the NASDAQ 100 using this strategy on historic data and when the backtest finished running it showed all of the 100 symbols but all the stats just say 0.00 0.00 0.00 1.00 .000% etc. Why would this be?

I don't have experience with the Nasdaq100, I only trade futures. But shouldn't you run a backtest on each symbol individually instead of all 100 at once ?

[dr0832]

How do I undelete it? I think I created that strategy and then in the middle of t I tried to create two new strategies with the same indicators and since they are linked it somehow was preventing me from compiling the original strategy since the other two were not complete. I thought I was suppose to backest on a basket of symbols but maybe I am mistaken. I will try just one symbol and see what happens.

[marcow]

How do I undelete it

Unless you shift-deleted the file, in the windows explorer window rightclick -undo delete- ? Or maybe the file is still in the recycle bin ?

Very unlikely that was the cause of the problem.

Thanks for the assist marcow!

dr0832, are you able to compile your scripts well now?

For the backtesting, you can basket test on the whole index list or on a single symbol. If you test for example the NT inbuild SampleMACrossOver strategy on your data, would you get more significant results reported?

Thanks,

[dr0832]

Yes i believe I would get better results on a basket however I can't seem to get it to backtest correctly.

[NinjaTrader_Bertrand]

Ok, so what if you backtest our default shipped strategy 'SampleMaCrossOver' - any results seen on your dataset?

Thanks,

[dr0832]

The backtest works correctly when id that.
