Is there a way to turn this off?
It dramatically distorts all the numbers and I can't seem to get it to work correctly.

This is the only thing I can think of, since I have one trade that shows under the individual stock result as +1.5% and held for 1 days but it says my return is ~450%, and a 7% return held for 9 days as ~300%.

Also, if it drops 1% in 1 day then I get out, it will be counted as a 450% (or so) loss.  I constantly "take" 3-5k losses and gains, according to stockfinder.  While this is kind of entertaining, it definitely does not help me in the slightest to refine my trading.  Thanks in advance.

While you can ignore it, there is no way to disable the Annualized Return per Trade in BackScanner (it is overstated in StockFinder 5).

So I have to manually go through and add up all the returns from the individual stocks to get an accurate total return, accurate drawdown, etc.. ?

Annualized Return per Trade isn't used at all in calculating any of those things. The best available way to determining overall performance of a strategy in BackScanner is to use the Equity Line.

BackScanner isn't a trading simulator. It doesn't have any money or portfolio management features at all. You are either all in or all out and your investment is evenly split between your trades. It is not going to show you how a strategy would play out if you were attempting to implement the strategy.

All it can do in its present form is to give you some idea of the strategy is good or not and allow you to have some basis to use when comparing one strategy to another (but not to the real world).

Well, I went through and manually did the math, which does in fact make sense.  Ugh-- there IS such thing as too much data :)

The Annualized Return per Trade in StockFinder 5 is overstated. Even if there were not the case, it is probably not a particular useful metric for comparing strategies. Very short trades will have dramatic influence on the results compared to longer trades with similar returns.

Divide the annual return by 3.69 for daily backscans to get a reasionalble approximation.. The boneheaded calculation is daily using time in the market of 6.5 hours instead of 24. A bug since day 1. Pretty pathetic that it has never been fixed. 24/6.5 = 3.69
