Practically, there are two types of the sum of positive gain, 1
1/ Full Gain, at the KO day, you could take all the positive gains; 2
2/ Capped Gain, at the KO day, you could only take the positive gain capped;
Per the positive gain pre-decided, you could be showed as big figures (pips) or real amount.
Apart from the sum of positive gain as target, we also have the sumcount of positive gain timesoccurrences as target, say 3 times positive gain will be KO, whatever the real amount of gain is.
