[amibroker] I need your input on an Optimisation issue

I am currently optimising a trading system over 1 year of data, and 
sorting the results by Gross Profit Made.

What I am finding is that the system has long periods of small losses 
then one big gain. Although over a year this provides a good return, 
drawdowns in the interim are bad - and I am looking for regular 
cashflow with lower drawdowns rather than the largest gain made over 
a year.

Can anyone think of a way to optimise results for maximal cash-flow 
each month rather than Gross Profit Made in a year? Is there a 
mathematical formula I can use?

I tried using a average of x bars, but this still doesn't solve the 
problem, eg:

Week 1: $40
Week 2: $40
Week 3: $8000

averages $2693.33

whereas I would like more:

Week 1: $900
Week 2: $1500
Week 3: $2000

(this is a very simplified example but illustrates what I am after).

Many thanks,
Alex
