Hi AegeanFutures,
Thank you for sharing your algorithm with the community.
In the above, the indicator would have wrong values as it would be updated twice as the helper method(self.ATR(), self.EMA())  already registers the indicator for updates.
Best,

Thanks for sharing, i'm curious about the futures bit.  Does this effectively trade continuous futures? Versus a single contract?

I don't live trade any algo's currently .ekz, I use the platform here to backtest ideas I use for discretionary futures trading. In backtesting it is the industry standard in many cases to use continuous futures contracts, particularly if you are doing any kind of long/short trend following system. If I were to setup a shorter term algo to day trade akin to the one above I would always use the contact with the most traded volume currently. I posted the code above to show others a way they can implement oco orders as I was having trouble finding a useful example for myself. If you would like to use the code take Farads suggestions and implement 

self.ema = self.EMA(self.crudeoilwti.Symbol, 20)
self.RegisterIndicator(self.crudeoilwti.Symbol, self.ema, timedelta(days=1))
       
self.adx = self.ADX(self.crudeoilwti.Symbol, 20)

self.RegisterIndicator(self.crudeoilwti.Symbol, self.adx, timedelta(hours=1))
       

instead using this format-

self.ema = ExponentialMovingAverage(20)

self.RegisterIndicator(self.crudeoilwti.Symbol, self.ema, Resolution.Daily)

Hope you found this helpful, Best Regards 

Thanks for the reply AegeanFutures. 

I realize now that my question was not entirely complete/well-worded.

For additional context: Most futures algos that I've seen in the forums trade individual contracts – I'm yet to see an example with continues futures, much like one would trade a stock symbol with technical indicators. It seems that is what you have here.

Varad Kabade : is the above a good implementation of a continuous futures strategy? Would you advise using this as a template?

.ekz, what I posted was just to show people how to place oco orders when entering with a market order. The examples I'd found only showed the adding of stop and take profit orders in the onorderevent handler and when entering with market orders this did not work for me. Here is the standard template for using continuous futures. If you use a trend following system and your broker offers continuous contracts this would be a good idea to use for trading pin order to reduce fee's when rolling to new contracts imho.

Hi .ekz.,

It must be because I see that thread pop out every other day but (re-)check 

😊

First algo, second algo with SMAs, etc.

They look like they trade continuous futures.

Fred

Got it. thanks AegeanFutures and Fred Painchaud !
