formula.rule entry description
The [formula.rule] entries follow this format : formula.rule.sensitivity.riskClass
-
sensitivity field, lowercase.
-
riskClass field, lowercase and the spaces are replaced by -.
-
The sensitivity field can contain the sensitivity metric name (sensitivity_kind) or the sensitivity provided name (sensitivity_name).
The lookup order is the following :
Order | Lookup |
---|---|
1 | formula.rule.sensitivity_name.riskClass |
2 | formula.rule.sensitivity_name.* |
3 | formula.rule.sensitivity_kind.riskClass |
4 | formula.rule.sensitivity_kind.* |
note
For the dividend metric, the lookup is first on sensitivity_kind and then on sensitivity_name.
The formula value has the following entries separated by commas: formula,priceFactor,derivativeOrder,interpolation,shift
Entry | Position | Meaning |
---|---|---|
formula | 1 | The keyword defining the used formula. |
priceFactor | 2 | A scale applied to the sensitivity ( sensitivity * priceFactor). |
derivativeOrder | 3 | A number defining the derivative order or the sensitivity, 1 for delta, 2 for gamma. |
interpolation | 4 | true means interpolation of market data is allowed. |
shift | 5 | A shift that is added to the sensitivity ( sensitivity + shift ). |
The following formulae are available:
Formula | Meaning |
---|---|
Absolute | $$ pnl = sensitivity \cdot \frac{ \left ({(quote_T \cdot priceFactor) - (quote_{T-1} \cdot priceFactor)} \right ) ^ {derivativeOrder}}{ derivativeOrder!} $$ |
Relative | $$ pnl = sensitivity \cdot \frac {\left (\frac{quote_T \cdot priceFactor}{quote_{T-1} \cdot priceFactor} - 1 \right ) ^ {derivativeOrder}}{derivativeOrder! } $$ |
DHS | $$ pnl = sensitivity \cdot \frac {\left (\frac{quote_T \cdot priceFactor+shift}{quote_{T-1} \cdot priceFactor+shift} - 1 \right ) ^ {derivativeOrder}}{derivativeOrder! } $$ |
FXRelative | $$pnl = sensitivity \cdot \frac {\left ( 1 - \frac {quote_{T-1} \cdot priceFactor}{quote_T \cdot priceFactor} \right ) ^ {derivativeOrder}}{derivativeOrder!}$$ |
