I am pretty new to this but was hoping to break into the algo trading world. I am looking for a couple of mean reversion algo's written in python. I am looking to start on the EUR/USD, and then branch out from there. I was hoping for a pretty simple algo so that i can use that as a blueprint and expand it once I get more experience. Any help would be appreactiated.

I am having trouble doing these things in python
#finding the current price and making that a live variable
#finding the mean and making that a live variable
#deciding on the difference needed to pull the triger
#finding out how to do a buy Order
#finding out how to store the current price as a non-live variable
#finding out how to take profit and stop loss
#finding out how to do a sell Order

We can find the price of a given security anytime in the Securities object:
price = self.Securities["EURUSD"].PriceHowever, if we are at the OnData event handler, we are receiving that data:
# OnData(self, slice) price = slice["EURUSD"].ValueThe mean of a price series can be calculated using the SimpleMovingAverage indicator. The SMA helper method creates that indicator and updates it accordingly:
# Initialize # 30-day simple moving average with daily frequency self.sma = self.SMA("EURUSD", 30, Resolution.Daily) # OnData if price > self.sma.Current.Value: # Buy order, stop order and take profit order go herePlease checkout a working example below:

Thanks Alexandre! I'll take a look and try to make my own.

Hi Alexandre, thank you, I was followin your advice.
Is there a way to get the Bid or Ask price for a currencypair? I see this documentation for Options:
...but for FOREX I cannot find any reference in the documentation for "chain/chains". Any idea?
István Kürtösi
In the meanwhile I think I found the answer in other comments, so there are no Bid/Ask prices for FOREX:

When we access the data in the Slice object we receive in OnData(Slice), we can get the Bid and Ask like this:
// In OnData(Slice) // QuoteBar object has OHLC Bid and Ask var quoteBar = data[atmContract.Symbol]; bid = quoteBar.Bid.Close; ask = quoteBar.Ask.Close;Alternatively, we can use the Security object in other methods:
var symbol = atmContract.Symbol; bid = Securities[symbol].BidPrice ask = Securities[symbol].AskPriceIstván Kürtösi
Hi Alexandre,
thank you for your answer, so I was wrong above, sorry about it.
Also for others, probably it helps, here is an example of applying your code in Python:
quoteBar = slice['EURUSD'] bid = quoteBar.Bid.Close ask = quoteBar.Ask.CloseBill McCabe
