Besides trading simple PCIs from single instruments, a trader may create and trade portfolios from several instruments.
In case of portfolio trading, the base and quoted parts of a synthetic instrument consist of portfolios (stocks of hi-tech companies, precious metals, currencies, etc.).
For example, having created the portfolio from the stocks of hi-tech Apple, Google, Facebook companies against the stocks of Exxon Mobil and Chevron oil companies (AAPPL_GOOG_FB/XOM_CVX), a trader may make a comparative analysis of the two most important industries of the US economy and reveal trends on the basis of which he will develop his trading strategy.
Such analysis can be carried out on PCI too, comprised of stocks of any energy company, as the base asset of the PCI pairs with Brent oil, which is the quoted asset.
A more complex personal composite instrument may be created, which will include the combination of stocks of major energy companies in the base part and Brent oil in the quoted part, and its analysis is made in the similar way.
Having created a portfolio personal instrument, a trader may trade it as any other financial instrument during the trading hours of all the included components.
