Whenever I try to save my current layout (I save whatever I'm working on as "Latest"), it gives me an exception, and fails to save. The layout has two strategies plus the Signal Hub and Debug Log panels. Here's the first part of the exception message:

From TASC May 2016 - Backtesting A Mean-Reversion Strategy In Python

APR: 7.89% • WIn Rate: 72.76% • Sharpe: 2.04

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.

APR: 25.75% • WIn Rate: 37.78% • Sharpe: 0.65

In the last few weeks, I've been playing around with my custom universes. I noticed that when I have a model open and I change some symbols in the models select universe, the changes are not applied. I first have to close and reopen the model, so that the modified universe is adopted. Can this be fixed?

I've been a mac user for the last decade or so, but three months ago bought a Dell laptop just for running Quantacula and other trading software. Last night I came home and opened up the machine to a black screen. I did everything I could find to do, sought help from longtime friends who fix such machines, nothing worked except the last straw: Reset This PC. It saves your personal documents, but deletes apps and reinstalls windows.

Request to choose, whether an Equity Chart will be shown in logarithmic or linear scale. Would make sense, specially for a long term equity curves when position size is driven in percentage.
Is this feasible?

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.
