Before starting the current round of major backtesting, I evaluated several tools to decide which to use. This article shares the highlights of that endeavor and the main reasons for the outcome.
TradeStation was my incumbent. By 2007 when I made my last evaluation, I’d had a couple years of experience with it as a charting tool and a backtesting engine. I’d also used TradeStation Radarscreen to scan the market for opportunities, but found it awkward and slow. The backtesting had proved reliable but limited to running one stock at a time. Then TradeStation came out with two critical enhancements: a means to read in outside data for historical prices, and hooks to automatically process more than one stock per run.
Another favorite tool is Telechartwhich has been my top-down market analysis tool since 2005. It doesn’t have a backtesting engine. However, in early 2007 the Worden Bros who make Telechart had just come out with the Blocks Backscanner. I tried it out extensively and really liked the super support as well as the flexibility. Its strength is scanning through a huge list of stocks in incredibly fast run time. But as a very young tool, it didn’t yet have all the features I wanted like independent data sources. Plus, it was so new in 2007 that I often felt like a beta tester which is exciting but not what I was looking for to prove out trading strategies.
I didn’t get past reading the specs on other backtesting tools. Trading Blox seemed to locked into their own strategies, plus a very high price tag. I’d previously been exposed MetaStock, struggled with it back in 2004, and was not keen on revisiting it. I had heard good things about Wealth-Lab but didn’t want to get locked into Fidelity, and didn’t see all the features I wanted there either.
So basically my choice came down to the new Blocks or my old standby TradeStation. I came to the conclusion that the optimal way to proceed was to rely on each tool’s strengths. So I use TradeStation for backtesting because I can set up the large-scale, controlled software environment for it. This gives me a way to prove out a strategy which I do only once per strategy.
Once a strategy is proven and I’m ready to trade it, I usually want to scan the market for opportunities to apply it. I do this daily, after the market closes, using Blocks 2.0 because it is so very fast at scanning the market.
I recently attended a class on Worden Stockfinder 4.0. It looks promising — the Blocks program grown up and renamed. I’ll review my impressions in another post.
