IMO
you have too many trades and not enough traffic
you need to lose the first click to gallery
you should get rid of the bonuses
you should lower your return cap ratio to 140 and set your main ratio to 10
you should be buying a lot more than 30hits/hr to feed a site
there's also other settings in TP that aren't shown on this page that can help or hurt your site like
are you using the anti-cheat
are you using the multiple page feature for non unique visitors
what are your traffic weights
what are your out settings
also, why to you have different ratios for different trades?
are you trying to out-think the traffic script?
last thought... I've seen several posts like before and I think your asking the impossible of a traffic script with such small trades, because it has nothing to work with. The more traffic it has, the better choices it can make in returning traffic.
Hope that helps, don't give up
