Traders will not be able to trade with the AMM for options with deltas outside the specified cutoff for a given asset, including closing trades. For example, imagine that the delta cutoff range for an asset is 15-85 delta. A trader might open a trade buying a 50 delta call, if the price of the underlying asset rises and the option becomes 90 delta, the trader will not be able to close with the Lyra AMM unless it falls back below 85 delta. Note that if an option falls outside of the delta cutoff range, and then returns to the tradeable range, the option will once again be tradeable with the Lyra AMM.
