Esignal automation......

[Bleemus]

It seems a lot has changed at Ninja since I last used it. I have the sim model now and am working on a new automation.

My old files don't work anymore due to the changes and I was hoping someone had some basic code to post to get me started.

What would be most helpful would be something like a simple buy or sell script based on a basic MA crossover. I don't need to do all of the cancel stuff just the checking to see if it is in a trade. Once an order is passed off to Ninja I want Ninja to handle it and avoid coding in Esignal to be changing orders, cancelling orders etc. The beauty of Ninja is that it handles orders better than anything out there and would rather use it's power than rely on Esignal generated stuff. I never need to manipulate an order beyond what Ninja can do once it has the order.

Does anyone have a basic MA crossover script that sends the buy or sells to Ninja that they can post to save me countless hours of testing and testing? This would be a great help as I can modify it for my particular strategy but the fine points of getting the OIF created and sent are causing me problems.

I spent about six hours on it today and have gotten nowhere.

Regards,

Please take a look at the eSignal sample script <install>\bin\AutoTrade\NtSample.efs.

Unfortunately I'm not enough an EFS expert to provide a real-world MA cross oever.

Anybody?

Thank you Dierk!

It appears that a lot has changed by going with a .dll instead of an .oif file. Looks like I have a lot to learn to get this working.

Checking the documentation on the site it appears that .oif is still supported. Is there any particular advantages of one over the other? I would think .oif is simpler while .dll is more powerful.

I am not a JS programmer by any stretch and when I last used Ninja I had a friend help me with the coding. Looks like he may be busy again.

Here is a simple EFS for a MA crossover with some ADX filtering made using the Wizard in Esignal. It is only Buy side. Just threw it together this morning in case you wanted to see it. I doubt you could make money with it!

DLL advantages:
- no file locking issues
- more features supported
- faster than OIF interface

Thanks, I will look into the .dll functions more when I return from golfing this morning and see what I can put together. I quickly patched the MA script together with the NT Sample script and it does connect to Ninja. Just have to start tweaking the code to get the orders passed along.

Beifall und gutes Handeln!

Also, there is not additional experience required to get your EFS to work with the OIF based format or the DLL approach. It's actually likely more easy since there are a bunch of eSignal functions built that wraps the DLL.

Ok, am learning it a bit. I do appreciate the help.Can anyone shed some light on the following.......

In my script editor I get the following syntax error.....


line 123: SyntaxError: missing formal parameter:
function NTCommand(PLACE, Sim101, BUY, 3, MARKET, "", "", DAY, "", "", YM, "") {

..................................^


Here is the code that surrounds the offending line......


function onAction1() {
drawTextRelative(0, low(-10), "Buy", Color.RGB(0,128,0), Color.RGB(255,255,255), Text.BOLD, "Arial", 10);
drawShapeRelative(0, low(-5), Shape.UPARROW, "", Color.RGB(255,0,255), Shape.LEFT);
Alert.playSound("C:\Program Files\eSignal\Sounds\YMbuy.wav");
vLastAlert = 1;

// Submits a NinjaTrader command.


function NTCommand(PLACE, Sim101, BUY, 3, MARKET, "", "", DAY, "", "", YM, "") {

return dll.call("Command", command, account, getSymbol(), action, quantity, orderType,

limitPrice, stopPrice, timeInForce, oco, orderId, template, strategy);
}

You might want to take a look at the strategy sample: <install>\db\AutoTrade\NtSample.efs: There you'll see how to declare dll function wrappers and how to call them.

Thank you Dierk. While I have sailed around the world, worked on a hedge fund trading desk, won the Doublehanded Transatlantic Race, shot 74 on a tough golf course, been scuba diving on Mellish Reef and raised two wonderful children I have yet to learn Javascript. I will keep trying or just go to Tradestation.

Appreciate the help.

>... I have yet to learn Javascript.

And it will still probably be the most frustrating, confusing and infuriating thing you ever do...
