# Which is the most important stat to you?

Discussion in 'Strategy Development' started by TradeNYSE, Aug 1, 2007.

Working with my current trading strategy and trying to optimize the system. Assuming there is one variable that can directly affect the number of trades, profit/loss, which is most important to you and why?

For ex. (just to clear up)
Let's say if 1x was used as the variable the results were (YTD):

Wins = 1731
Losses = 1304
Win % = 57%
Avg Win = 1.79%
Avg Loss = -1.60%
Avg Win/Avg Loss = 1.07
Total Buying Power Required for all trades for entire year = \$60,740,000
Profit = \$102,611

Now the variable is 2x:
Average profit/trade = .51% (+.17% higher than 1x)
Wins = 1061 (less trades triggered)
Losses = 719
Win % = 60% (+3%)
Avg Win = 1.99% (+.20%)
Avg Loss = -1.68% (-.08%)
Avg Win/Avg Loss = 1.19 (+.12)
Total Buying Power Required for all trades for entire year = \$35,600,000
Profit = \$90,529 (roughly -\$10k)

My question becomes...are you more concerned with the bottom line (where 1x profits more than 2x), or are you more concerned with another ratio/number? What ratio/number/stat would you focus on (I do not have a statistics background, so I am sure I probably left out some very crucial calculations that could help me...that is where I need some input).

I mean from a common sense standpoint, I can look at this and say that 2x is a much better/efficient way b/c you lose \$10k in profits, but you risk almost half the money in buying power over the year. But What if I have 50 different variables and want to pick the best one?

Hips, waists, and breast?

On a more serious note though, I tend to be more concerned with my drawdowns. How large are they vs my upswings. How long does it take to recover from a drawdown? How much of my return depends upon the market? Things like that are important to me. Plus Hips, Waists and Breasts.

Thanks Brandon...but looking for something more statistical and not discretionary.

I use Vince's Weighted Geometric Mean as my primary stat along with SDevRatio and a few distribution stats.

Have a good idea of how and why the largest losses occur. This will reveal the biggest flaws of your method and keep you from being on an unnecessary roller coaster ride.

Ok let's try this again:

System 1
TOTAL PROFIT \$154,626
WIN 1632
LOSE 1068
WIN % 60%
AVG WIN \$220
AVG LOSS -\$192
WIN/LOSS[abs value] 1.15
RETURN (profit/capital used) 0.29%

System 2
TOTAL PROFIT \$166,573
WIN 2130
LOSE 1484
WIN % 59%
AVG WIN \$206
AVG LOSS -\$184
WIN/LOSS[abs value] 1.12
RETURN (profit/capital used) 0.23%

Which would you choose and why? Are there other calculations you would want to compare that are not listed that would help you decide?

Didn't answer my question, but thanks for the input.

None of the above. I like to look at sharpe/sortino ratios. This gives you a good idea of the risk/reward.

Can someone help me with what I need to do with my data to get the numbers required to calculate the sharpe/sortino?
