Mentioned securities account held derivatives also. Derivatives are especially futures, options and ETF funds that invest a substantial portion of its own assets in futures and options. Furthermore, the work describe how it is possible in the forensic practice prove the "control of trader over customer account". It is also discussed the issue of calculation of indicators (esp.
