As far as I understood the task it is:
- take a random direction entry
- define your money management rules for a trade
- trade with this
The goal is to prove (or not) whether money management rules alone (and only MM rules) can be profitable if your direction is random. The base for this are those calculations which say for example that a CRV of 2% needs a hit quote of 33% to be profitable. (Which again means, if your theoretical chance is 50:50 – what it is by random definition – a good MM should be profitable.)
No question that there are other approaches which are based on chance optimization (all kind of indicators are based on the assumption that you need to have a better chance), but as far as I understood that was not the original task.
