Volatility and envelope measures describe the distribution of recent movement; they do not set a maximum possible move. Parameter choices, timeframe and data quality can materially change the result.
Use in bonds, rates and macro markets
Rates volatility can respond abruptly to policy repricing and data releases, so historical bands should never be treated as hard limits.
Technical chart structures are context, not certainty. BondStats does not present a candlestick, drawing tool, indicator reading or chart pattern as a standalone investment recommendation. Where a concept depends on discretionary anchors or parameter choices, those choices should be made explicit.
