Facts:
1) Commission fees are always a part of a trading system.
2) Commissions are individual for every subscriber.
3) When a developer created a trading system, he/she certainly counted with some concrete value of commissions and subscriber fees.
Suggestions:
a) Commission fees must be included in a system description just like subscription fees are.
b) Developer should fill this parameter as his/her suggestion for subscribers in system details page.
Everybody can see it in public as a system’s parameter.
If there will be zero in commissions (the developer did not fill the parameter, it can be taken as a warning for subscribers.)
The changes in developer suggestions should have a history just like the change of trading system has.
Ideally the concrete broker should be mentioned. (= another trading system parameter)
c) Commissions are individual for every trader. “Typical commissions” is a nonsense.
Everybody should have a possibility to apply his/her commissions. (This is probably possible already.)
d) Thumbnails without commissions.
