Most widgets (Stress Test, Risk Attribution, Backtest) can display information either from all the positions in the portfolio or alternatively only a subset of securities to emphasize the contribution of the subset to the whole.
A sophisticated filtering language controls what is displayed in the widgets. Widgets that have been pre-processed with a filter have the name of the filter on its title. For example, a stress test that has been pre-processed with the exposure filter will have the filter expression available as you move your mouse over the word Filter (see figure below).
The following basic filters are currently supported:
| filter Name | Example | Explanation |
|---|---|---|
| currency | currency(‘foreign securities’) | This filter extracts different currency related buckets. The choices are: ’foreign securities’,’domestic securities’,’currency hedges’,’non-USD currencies’. |
| exposure | exposure(‘short’) | The choices are: ’long’, ‘short’. This filter extracts securities that represent long exposures (including long calls and short puts) and short exposures (including long puts and short calls) |
| type | type(‘equity option long delta’) | Retrieves different types of securities. The choices are: ’equity option long delta’,’equity option short delta’,’future option long delta’,’future option short delta’, foreign equity long’,’foreign equity short’, ‘us equity long’,’us equity short’,’fx’ |
| liquidity | liquidity(‘0-5%’) | Retrieves different securities according to their liquidity. The choices are: ’0-5%’,’5-25%’,’25-50%’,’50-100%’, ‘100-300%’,’>300%’ |
Filters return only the IDs of the selected securities for further processing. Furthermore the basic filters above can be part of more complex logical expressions.
