Moving average crossover strategy is one of the popular strategies that lots of traders have paid attention to. The details of the strategy is described at Wikipedia. https://en.wikipedia.org/wiki/Moving_average_crossover
In a short summary of moving average crossover strategy, the trend of the security is going up when the fast moving average line cross over the slow moving average line from the lower area and it is a signal about long positions.
In the following example, the code calculates the moving average of 5 (fast moving average line) and 15 (slow moving average line) at 15:59:00 US Eastern time, 1 min before the market closes, on every trading day. It places an order of SPY, ETF tracking S&P 500, when the fast moving average line starts to cross over the slow moving average line and exits the positions when crossover happens in the opposite direction.
The code can be backtested at Quantopian.com because IBridgePy can run most of the strategies posted at Quantopian without any changes.

Hi!
The following message
AttributeError: module ‘pandas’ has no attribute ‘rolling_mean’
is displayed when running the code. Any ideas how to fix it? Thank you.
Try just importing pandas.rolling_mean at the top of whatever script your running

Hi,
Tried importing pandas.rolling_mean but got an error below.
ModuleNotFoundError: No module named ‘pandas.rolling_mean’
Any idea to fix it? thanks
Can I use only IBridgePy & TWS without Quantopian?
Your code, as presented, above “runs” error-free but no results.
Is there a complete example (single script) that does say MA crossover in Spyder(3.2.8) with Anaconda36_64 including connection to kernel?
thanks
I have the same issue “Your code, as presented, above “runs” error-free but no results.”
The trading decisions are made once a day. If you run the code for a few minute, it is very likely you won’t see any meaningful results.
I had a question what should I do if my algo gets disconnected due to some issue so all my information saved in context variables would lost what should I do if my algo gets disconnect and I reconnect all varible info is loaded again ?
If you hard-code information in context variables and run your algo again, they will show up again. If you save information to context variables during your code, you may consider to write to a csv file and read them in as needed.
what logic should one put to detect the algo has disconnected and when
what is in my mind keeping the iteration count of handle data and one the algo gets disconnected iteration count and then i start algo say 5 minutes later say algo got disconnected at 10:15 and i restarted algo at say 10:30 . and lets handle data is running every minute so in my variable where i was recording the handle data iterration count it would have 60 assuming market started at 9:15 and when i restarted the algo at 10:30 iteration count of handle data should have been 75 which is not so program would know the algo was disconnected and load information in context variables through CSV where I have recorded them do u think this is a good logic to loading a previous information in context variables when algo gets disconnected or can u give some suggestions
