Computer system and method for securing market profits of financial instrument investments

A computer system for securing market profits of financial instrument investments comprising:

• a storing mechanism configured to electronically store a yield target for a purchased financial instrument species;
• an acquisition mechanism configured to electronically acquire a current rate of the instrument species;
• a calculation mechanism configured to calculate a yield of the purchased financial instruments and to compare the calculated yield to the yield target,
• wherein the calculation mechanism is configured to:
• implement, if necessary, one or more recalculations and recomparisons with rates respectively newly acquired by the acquisition mechanism until the calculated yield is higher than the yield target;
• store, given a first-time and every further occurrence of this case, the calculated yield target as a new yield target in the storing mechanism and, if necessary, implement one or more recalculations until the calculated yield is lower than a respective, new yield target and does not lie within a tolerance value;
• the computer system further comprising:
• an output configured to provide an instruction to sell the instrument species when the calculated yield is lower than the new yield target and does not lie within a tolerance value.
