The week the TWAP guard earned its keep
15 blocked actions are now in the ledger. Here is what each of them was refusing to do.
A price guard is a cost until the day it isn't. Ours fired repeatedly this week during a thin overnight window when the GME pool printed a spike that the 30-minute reference did not corroborate. Each time, the rebalance aborted rather than resetting the range around a price that reverted within minutes.
The forgone fees from those missed resets are real and small. The alternative — placing a fresh range around a spike and holding it as the pool snapped back — is how a managed position converts a temporary dislocation into a permanent loss. We would rather publish the refusals and explain them.
Every blocked action carries its deviation figure in the detail column, so the trade-off is auditable rather than asserted.
