How to Backtest a WatchList

I am totally confused by your interface and documentation. The software looks very powerful, comparable to AmiBroker in terms of capabilities and apparently easier to accomplish complex tasks with fewer and simpler commands. I understand and can program in AmiBroker which I considered the most poorly documented trading software ever. QuantShare has changed that opinion.

Let's start with a simple situation/question. I set up a watchlist of about forty ETFs (I think). I can find them via charting by typing in the symbol so I know they were added to my data although I am not sure the watchlist any longer exists. How do I find that? How do I backtest only those symbols?

I cannot imagine the dollars being lost in this process. I am not a newbie in terms of trading or trading software having used MetaStock, ThinkorSwim, AmiBroker, TradeStation, OmniTrader, TC2000 among others. I have programmed and backtested in MetaStock, AmiiBNroker and ThinkorSwim. Custom indicators have been written in more than these.

I might also add that I have a PhD in Finance (possibly an excuse for my ignorance). I have ten days left on my trial and have not been able to run a simple backtest. I have printed out your entire "manual" and attempted to make sense of it. (Would it be too much to have page numbers on the Table of Contents? Probably not, because even when I search the topic down it doesn't seem to make sense.)

In any case, in one last attempt to be enticed to purchase your software I send this. Again, I cannot imagine how many people are turned off via the documentation/learning process. If the software is as good as I think and others suggest, you are losing a lot of sales you should be getting.

ADD: I had to copy this from the "How to" section where I wrote it. When I clicked on SEND it did nothing but lock up the process. ??????

Hi Monty,

Wathlist is used to keep track and filter securities pretty much like the screener.
The backtester or simulator is a different tool. The formula you used in the watchlist to filter securities can be used in the backtester.

We have a lot of tutorials on how to create trading system. You should probably read this one (includes video)

I am sorry but I don't understand the first question.

Thanks for your response. I set up a static watchlist containing the ETFs of interest. That apparently added them and their data to the database I was using (NASDAQ). It would seem to me that there should be a simple way of running a simulation backtest on items both in the database and the static watchlist. That is, the backtest would ignore all items except those in the backtest. How would one achieve that?

I assume that a massive database of stocks (say 10,000) could be screened based on some criteria, added to a watchlist and then tested by the backtester. Perhaps that is not the case. For what I have done is added ETFs to an existing database without adding an identifier field. Thus, there is no way to screen them out of the database unless a watchlist can be used in the process.

Once you download data for your securities, you can create a new trading system and select the "Symbols & Dates" tab.
In the "Symbols" panel, you can add one or several conditions to select the securities to backtest.

Example:
Add "Custom Symbols" condition then enter the tickers you want to backtest
Add "Internal List" condition, click on the cell under "Values" then select "Watchlist -> Static Watchlist then your watchlist"
