 - `CONSECUTIVE_FILTER_MATCHES` - How many times in a row pool needs to match the filters.
   - This is useful because when pool is burned (and rugged), other filters may not report the same behavior. eg. pool size may still have old value
+- `CHECK_IF_MUTABLE` - Set to `true` to buy tokens only if their metadata are not mutable.
 - `CHECK_IF_MINT_IS_RENOUNCED` - Set to `true` to buy tokens only if their mint is renounced.
