Sounds like you're describing Collective2. Covestor used to do the same thing but they were bought by Interactive Brokers and I'm not sure what they are doing now.
If I was such a wildly successful trader, why would I wanna share my trades with anyone? Those who do openly share their trades with the public have an ulterior motive and should not be trusted.
Sounds like you should open a trading floor. My old job as a trade support clerk let me look at all the trader positions just by clicking on their tab. That was my chance to learn from very good traders but instead i just wasted my time buy sell my own account.
I know this will sound obvious. This is what I do...I'm an investor, not a trader. I look for good companies (industry leaders). They must have a "wide moat" (think Apple). They should/must have a bad quarter, but retain their dividend. You must figure out if it's a "one off", (deferred maintenance/planned layoffs) or a real problem with the company. Apple had many "one offs" over the years. Companies like AOL, Yahoo, GM have/had structural problems that could never be fixed... I don't go heavy into any one company...it's courting disaster. DO NOT DOUBLE DOWN...
