Wealthlab 2018 Update The SThere is no error message.Updating Provider Reuters news. It's a problem on your end. The provider is functioning absolutely correctly. The paper focuses on two questions.Eugene, It's not a problem with my internet connection because I can update the S&P 500 list without problems if I select Google News.Wealth-Lab Pro 6.9.17 can be downloaded from our software library for free. The most recent installation package that can be downloaded is 16.1 MB in size. The latest version of Wealth-Lab Pro can be installed on PCs running Windows XP/7/8/10, 32-bit.The bleak reality is that most back testing software is horribly bad. ClenowChoosing a good platform for strategy modeling, simulations and signal generation is critical. Endorsements for Following the Trend by Andreas F. There is no specific symbol which blocks the download.That’s not how you make real trading models. Non-coders need not apply.Forget about drag-and-drop system building. I’m often asked for my views on simulation platforms, and in this post I’ll show you my own perspective and choices.Some have it, but just as a horrible after-the-fact implementation they slapped on top of an old platform just to get Portfolio in as a marketing check box.The development architecture and environment is very important as well. They’re not for professional use.A big problem with these consumer grade platforms is portfolio level logic. They won’t let you do anything outside of that box. They assume that you want to do a minor variant of some standard system and nothing else. I value flexibility.Most consumer level platforms draw a very narrow box around you. This article is of course written very much from my own point of view. Just do it.What’s important in a simulation platform?We all value slightly different things. Not “C-style environment” or some other way to say that you have a closed scripting syntax which vaguely resembles a real language. Industry standard development language. I have a severe allergy against proprietary scripting languages and closed platforms. Download java for mac 1068I want to be able to change or add any functionality I like. Things that never even occurred to the people developing the platform. I want to be able to do absolutely anything. Extremely open architecture. Not necessarily because it’s best, but because it’s certainly good enough and if you’re in an all Windows environment it’s a great language to standardize on. The ability to back test trading models on thousands of instruments, as a real portfolio. This is rare in affordable platforms. New visualizations, data adapters, broker adapters, database connectivity etc etc. I want to be able to make and plug in dll’s for anything. Didn’t I just say that in the last point? Yes, but it’s worth saying again. Nobody puts Clenow in the corner. They can can both be extended and modified by plugging in your own DLLs. I like them because they are both based on CLR, which means that you write proper C# code. They are both pretty good, but my preference clearly lay with RightEdge. If you trade instruments across multiple regions, this assumption breaks down fast.I’ve mentioned WealthLab and RightEdge in the past. Most platforms assume there’s only one currency in the world. There are samples available that you can modify. Overall usabilityThe good news is that it’s quite easy to build data adapters for both platforms. Despite the apparent similarities, they are very different to work with. Every time you open a chart or run a simulation, your DLL will be bothered.RightEdge on the other hand has it’s own optimized data storage. WealthLab will ask your DLL for a fresh data delivery every time the application needs it. Easy.A key difference however is what happens to the data after your DLL provides it. There will be an interface similar to (pseudo code): Public DataSeries GetTheData(Symbol, StartDate, EndDate)and you just put your own code that to scurry off and fetch from your database or whatever source you prefer. The architecture of WealthLab is clearly not built for portfolio testing. It.Here we start hitting the first weakness of WealthLab. I do this with simple scripting, using a good old bat file.Writing your own data adapter does require some basic C# knowledge. That avoids issues of data duplication and discrepancies. Faster, more efficient, but could lead to data duplication and maintenance issues.My solution is to flush the data storage daily and replace with fresh data from my primary source (my in-house MySql). When a chart is requested or a sim is performed, RightEdge will get the data from there. This will likely shock programmers. How could it, since all instruments are not processed yet.WealthLab iterates bars in a for/next loop. It doesn’t know the current portfolio holdings or even portfolio value. It has the unfortunate implication that the trading logic itself is totally unaware of anything happening to other instruments. This is not how the real world works. WealthLab processes one instrument at a time, going over each day for that instrument before moving to the next instrument. For this simple calculation, you need to know the portfolio value. You just take the current ATR as a proxy for vola and size your position to have a certain portfolio level risk. Take the classic ATR sizing, Turtle style. Well, it is in WealthLab.Let’s say you want to do some simple portfolio level sizing algo. Building your own is not that difficult. And I don’t mean trading currencies, I mean currency attribution. No need for ugly workarounds, since RightEdge implemented the data engine right from the start.If you want to do serious simulation work, you need to account for currencies. I made a volatility adjusted position sizer a while ago and published with full source code here: So what about RightEdge? The same thing that needs to be done in a complex plugin DLL for WealthLab can be done in a single line of code for RightEdge. Yes, you are unable to properly change position sizes in the application and you have to program your own DLL in Visual Studio just to set position size. Ugly.In WealthLab you have to make your own position sizing DLL. At the time when your code makes a trade, it hasn’t processed other instruments and therefore the portfolio value is unknown.WealthLab first iterates all instruments as shown above, registers when we’re supposed to buy and sell, and first when it’s done with all of it, it goes back to figure out how many shares/contracts to buy or sell.
