I just think that the "wall" that people are complaining about will always exist in that there are a lot of people competing for a fixed amount of demand, the people willing to go the lowest are the ones who make ANY return, and right now, you have people who are using the FRR in order to passively gain returns staying OUT of that competition at least some of the time (whenever there is a wall).
Do you understand the point of having a well-filled order book, In general? You don't seem to.
Margin traders should really be the ones taking you guys to task for this, since they're affected far more than lenders are. The issue is just more visible to lenders.
