Riven Grid

/wfm rivengrid

Like the riven inventory, you can create the same grids based off the listed rivens on a warframe.market profile.
These grids will contain information regarding grades and prices.
In cases where multiple variants of a weapon may be able to grade, only the first variant's grades will show.
SP: Starting Price
BO: Buyout Price
You may see the order of variants by running /rinfo.
