Backtest
You have a masterful strategy. How do you know it works?
Our backtest simulates running your strategy over years, and in a few minutes will give you a very clear idea how your strategy would have done in the past. We’ll show you 20 years of history, including the dot-com bubble and crash, the Great Recession, and the PIIGS Euro-crisis of 2011. We include delisted stocks in all of our simulations to prevent survivorship bias.

How Backtesting works
Imagine you’d read in a book to look for some strategy that claimed that growth was key. You put it in our system, and you get this:
Disappointed, you almost throw the book away. But then you start tweaking, and get something that actually outperforms.
If you’d read a newsletter selling this strategy below, you might be happy with the performance.
Presented with a graph, and the backtest by time, and you see that the performance is not so good recently.
So you make some more tweaks and arrive at this:
This is clearly what the doctor ordered (yes, we know it may not hold up in the future!). It outperforms almost every year.
And we run the numbers for you, so you can compare it against others.
