The way this question is framed suggests you might be hitting the same wall most people hit with market.
Let me work through the most likely causes from most to least common.
**Most likely culprit:** underpricing. This accounts for roughly 58% of cases I have seen.
**Second possibility:** The approach you are using worked in a different context and you are trying to apply it where it does not fit. small has specific conditions where it works well and conditions where it falls apart.
**Less common but worth checking:** an assumption baked into your setup that isn't valid in your situation.
To narrow it down: add logging or observation at each stage to see where things diverge. That will tell you which of these you are dealing with.
