This is the actual model originally described as the Golden Cross with the Death Cross as a sell and reverse trigger which is my own take on the strategy and note this is a time period 50 small sma periods and 200 large sma periods that has also been featured numerous times by technicians using a 10% of equity position size and as of the date I published this using my own custom watchlist I see one lucky long with triple digit returns and the rest plus or minus mid single digits so compared to the past results regardless this is not a good strategy and just here to test your money management skills and ability to program.

Could be an interesting System which was presented in TASC May 2019. I was astonished because there was no Quantacula sample code available, so I analyzed it in Ninja and SQL. Stocks which exhibit this behaviour for at least 15 years: ADBE AFG APC AROW BDX CASY CBSH COO ECL GATX JJSF KEX MCD MDT MKL MSFT OTTR ROK

The Simple Moving Average indicator calculates the average of a series of values using a specific lookback period. The result is a line that moves along the data, representing a smoothed version of the source.

I thought this would be easier. I haven't yet taken a deep dive to try and figure out how to create a Historical Data Source just to read a CSV file... but is that really what it takes? This feels like overkill. Am I missing something? Is there example code for a simple way to read a darn CSV file of prices?

The WealthSignals Adapter is a Quantacula Studio Broker Adapter that lets you submit trading signals to one of your strategies. WealthSignals is a site where traders can publish their trading signals, either from a mechanical trading system, or their gut, and garner subscribers who pay a monthly fee to receive the signals. If you have a system too good to divulge, consider running it on and earn some extra profits!

How it Integrates

You'll see the WealthSignals Adapter in the list of "brokers" in the Quantacula Studio Signal Hub. Log in using your WealthSignals credentials.

You can associate your Quantacula Studio model with a strategy in one of two ways:

  1. Name your model the same name as your strategy.
  2. Add the text WSCode=XXX in the model's description in Quantacula Studio, where XXX is replaced by the WealthSignals's Strategy Code. You will see a list of your strategies and their accompanying Strategy Codes when you log into the WSAdapter.


Submitting your Signals

Simply select the signals you wish to submit in the Signal Hub and then click the "Place Signals" button. If the submission was successful, the signals' status will change to Published.

While we're (well, I'm) on the subject of missing indicators, how about interest in the Hurst exponent, a trend indicator of sorts.? Lots of references to it out there.
