You very clearly haven't thought this idea through, or you don't understand equities.
* If a trader has a small stake, the information in his portfolio won't be worth sharing. It will constitute random noise in a business famous for the level of random noise.
* If a trader has a large stake, publishing his portfolio and his moves will have nothing but advantages to him, and nothing but disadvantages to his followers.
Consider Berkshire-Hathaway. The reason Berkshire-Hathaway does better than the DJIA year after year is because of all the uneducated fools who follow its moves -- too late for them to benefit, but just in time for Berkshire-Hathaway to benefit (because the latter already has a position before news of its trades becomes public).
To put it simply, publishing one's trades is only advantageous to the publisher, never to the reader. Experienced investors know this, so they won't bother to subscribe. Inexperienced investors don't know this, so they might subscribe, until they realize their mistake, then they will bad-mouth the enterprise.
Bottom line: before embarking on this plan, you need to learn how equities work.
