Are you speaking of thoseNBT traders who often successfully hedge with NBT and drain money from Nu?
They don’t need to have a tight spread.
The guys who just want to buy and sell some NBT need a tight spread, not the whales.
Parametric order book was made for that.
In the future there might be a very tight ALP with not very much order volume, which can be provided cheaply and bots run by Nu, which offer bigger volume at much higher spreads.
This way the big traders pay some money for the service Nu offers.
I have no intention to move the wealth of Nu to traders by offering big volumes at low spreads.
As I run the NuBot with Nu funds, I will of course follow each order that is given by motion.
I can only recommend to keep the orders close to the mid price small.
The current ALP scheme is not really matching that vision.
