Formula to be used for the purposes of Article 9(d)
Own funds requirement = – min (0,PC-DE)
where
PC (‘Price Change’) is the sum of price changes of the options with the same distinct underlying type understood in the manner described in Article 5(3) (negative sign for losses and positive sign for gains) and corresponding to the relevant scenario determined in step (c) of Article 9;
DE is the ‘delta effect’ calculated as follows:
DE = ADEV × PPCU
where
ADEV (‘aggregated delta equivalent value’) is the sum of negative or positive deltas, multiplied by the market value of the underlying of the contract, of options that have the same distinct underlying type understood in the manner described in Article 5(3);
PPCU (‘percentage price change of the underlying’) is the percentage price change of the underlying understood in the manner described in Article 5(3), corresponding to the relevant scenario determined in step (c) of Article 9.
