What is the cut off for FRAX?

Could you elaborate on the cut-off point for FRAX? As a cryptocurrency investor, I'm interested in understanding the parameters that affect the liquidity and stability of FRAX, a decentralized stablecoin. Is there a specific threshold or level that FRAX aims to maintain in order to ensure its peg to a fiat currency like the US dollar? Understanding these cut-off points would help me in making informed decisions about my investment strategies. Could you provide me with a clear and concise explanation of FRAX's cut-off mechanism?
