Hey guys, I've been using your tools for several years now and I have to say thanks for making this such a good product! I'm looking forward to the multi-core support!! :-)

I ran across something in the performance review tab that I haven't seen before and was wondering if this is an bug or a user training issue.

Basically, how can you have avg positive profit of 11% (in percent) while the avg profit (in dollars) is negative?

Thanks!

Thanks for the good words Derek. I have an explanation for this phenomenon:

Average profit ($) is simply = net profit $ / number of trades e.g. ($715) divided by 54.

Average profit (%) is calculated differently. Wealth-Lab loops over each position, summing up their net % profit, then divides the sum by the count and subtracts trading costs.

Not sure if it's right or wrong but considering that your wins outnumber the losses by a wide margin, I can imagine a positive number being produced.

Here's a simple example to demonstrate it. Ignoring commission, assume for Trade 1 you bought 100 shares of a $10 stock and sold it for a 20% profit at $12.00. For trade 2 you bought 1000 shares of another $10 stock and stopped out for a loss at $9.00.

You can make it work the other way too.
