Re: New Measures
In this case, there was a 3 in 4 chance that MaxDD didn't exceed 42.3% (or following, a 1 in 4 chance that MaxDD is greater than 42.3%). The question remains: what do you do with the information that the probability of MaxDD greater than 42.3% is 25%? Does it boost your confidence in the system? Do...

How does VeriTrader handle stops?
Veritrader testing engine might not treat those stops correctly(No inside bar lookback). If on a given bar both the profit target and stop loss stops may have theoretically been hit, how does VeriTrader handle this situation? The worst-case (and safest) scenario would be to assume that on such days...

It is a great feature but most testing platforms don't provide it. I'd say it will widen the gap between VeriTrader and other platforms :D. It seems, however, Trading Recipes allows multiple currency tests: Q15: Can TRADING RECIPES trade markets which are denominated in different currencies? A: TRAD...

To give a little detail about the system, it starts with FF and adjusts it down for capital, so as the account grows, you will still add contracts, but at an ever decreasing rate. So for the first trade, you might be risking like 8% (yep!) of account value, but when you add the next contract, you w...

While accounting for all possible tax rates and schemes may be difficult, if not impossible, I think it would be very easy to implement a feature that would allow you to reduce your equity at the end of each year by a user-defined tax rate, be it 10%, 20%, 40% or whatever. So if you paid a 20% capit...

Taxes
I wonder why no trading system backtesting platform that I know of accounts for taxes. Compounded annual growth rates are calculated as if taxes did not exist. I think taxes are a very important factor to consider. Why do platform designers think otherwise?

Closed-trade vs. open-trade drawdown
Hi traders and researchers, Which drawdown figure do you prefer to use when evaluating a trading system: closed-trade or open-trade drawdown? For systems trading multiple markets I prefer open-trade DD calculated every day on the close. I found that closed-trade DD often distorts the reality. For ex...

How to define low and high volatility?
In testing different systems for the Polish FW20 stock index future, I liked to use the 2*ATR stop loss and 5% risk per trade to determine my position size. This is the standard % risk model by which your position is bigger when the volatility is low, and it is lower when the volatility rises. Then ...

[...] Now, 1 year later and you are building a continuous back adjusted series. - There is a 10 point gap between sep02 and dec02. - Dec is 10 points below sep. - The splice requires the sep02 series to have 10 points deducted from all data points so as to align with the dec02 relative level. - Rem...
