Well, I don't really know about these stuffs but with my little knowledge I think these things have different use for example the positive and negative feedback.
The positive feedback will likely count when maybe you make a post and then someone goes through the post and likes the post for the fact that it was useful and helpful to him, then you are likely to get a Positive feedback count from that person the same thing goes to the negative feedback, you are likely to get a negative feedback in a case whereby you make a post and the post was not useful or important, or maybe the post even goes against the rules and regulations of the forum then a negative feedback is possible but for the trade count I really don't know about it.
