skipAuctionThreshold should be less than preferAuctionThreshold.
In StabilizerNode._triggerSwingTrader, it starts auction when purchaseAmount <= preferAuctionThreshold.
If skipAuctionThreshold >= preferAuctionThreshold, purchaseAmount <= skipAuctionThreshold always holds.
So in _startAuction, it will never starts an auction and does nothing. So the stabilize will not work in this case. It is recommended to check if skipAuctionThreshold < preferAuctionThreshold when skipAuctionThreshold and preferAuctionThreshold are set by the admin.
