Combining indicators continued

I am an X computer geek and I like rules.  You cannot write a computer program without rules.  Some stock systems allow you to implement trading rules....  If you have access to such a system then maybe you can use a rules based system real time.

I promised to show you the stock I used in last night's discussion of CCI/MFI combination.  Here it is:

If you examine the chart I think you will see this system would have captured a lot of the upsides (green horizontal lines) and avoided most of the dips (red horizontal lines).  I tried to test this on several stocks or ETFs.  How would it have worked on a bear ETF the past few months.  See for yourself:

Any help you can offer in testing this is much appreciated.  Also, if you have "rules" based systems you feel work please share.
