Hi.
My expression imput is: when ES 03-12:Bid - (minus) ES 06-12:Ask - FDAX 03-12:Bid + FDAX 06-12:Ask > 50 (for example) then SELL FDAX 06-12:Bid and at the same time BUY ES 03-12: Ask.
thanks

Hi.
I'm a newbie and I'd like to write a new strategy
My expression imput is: when ES 03-12:Bid - (minus) ES 06-12:Ask - FDAX 03-12:Bid + FDAX 06-12:Ask > 50 (for example) then SELL FDAX 06-12:Bid and at the same time BUY ES 03-12: Ask.
Stop Loss in case the expression is > 200
Close Trade when expression is <=1
No Stop loss
Using only 1 lot for each future
Really need help
thanks

There are several problems with this idea:


The Tool

If you want to trade spreads, NinjaTrader is certainly not the platform of your choice. You should go for X-Trader or something else.


The Spread Formula

Your spread does not make sense. ES trades at around 1350, the FDAX around 6700. You would therefore need to calculate a spread from 5 contracts ES against 1 contract FDAX.


Total Return Index vs Price Index

FDAX is a future on a total return index while ES is future based on a price index. That means that you benefit from dividends if your are long FDAX 06-12, but that you are not credited dividends if you are long ES 03-12.

As FDAX is a total return index, this means that it is in permanent contango, as dividend expectations exceed the financial cost associated with current low interest rates. ES however, is in backwardation, and will remain there, as it is a price index. The spread that you have defined, will therefore never ever revert to 0. So you do not need to write a strategy for an event that will never happen.


Conclusion

You gave us a false formula for a spread, which will never revert to the mean and want to code a strategy by using a tool which is not suited for the purpose.

Don't you think you should start with something simpler? I hope you do not mind my comment....

The formula is not the exact one I'd like to use.
The idea is to trade the calendar spread between ES march and ES June (or other futures contracts - NQ, YM, etc) and buy Ask March / sell Bid June if the condition is true (Bid June - Ask March - Ask June + Bid March > 2) at the same time, then close if the formula =< 0

I agree about differences between FDAX and ES (lots 5 to 1 and price index/ return index), it was only an example
I hope this clarifies my idea.
thanks

If you want to do that type of arbitrage, you will certainly need

-> direct access to EUREX and CME via membership (seat)
-> fast connection lines
-> other software than a cheap retail package

I would say that it is an occupation, where the retail trader cannot compete. Before you even trigger the order, one of the other guys will have already closed the window.

But of course it is relatively easy to code a NinjaTrader strategy. Add a few data series, then make sure that you execute the back months first, as they are not very liquid. You could ask somebody to write a strategy for you. This would at least have some educational value.

Thanks for your reply.
Could you give me some info regarding guys that will help me to write this strategy? As you wrote, this could have some educational value and maybe give somebody else an input for a different and better strategy.
regards

Have you looked at things like the CQG spreader ?
