I am not sure if this has ever been discussed or implemented. I'd like to explore the possibility to establish a union and define its goals in this thread, if you could help me to do so. First of all, do not have any bias. I am not a communist/socialist but a capitalist who employ myself. What is the primary goal of a union. I think it is to protect the members from harms such as being out of jobs. Unions monitor, negotiate, and fight in situations that the majority of members are mistreated. The counter parties of traditional unions are usually the employers of the members. There may not be the case for a trader union since independent traders are thought self-employed. However, these traders are exposed to extreme non-market risks imposed by regulators, exchanges, brokers and special interest groups, which are likely to be the counter parties of a union that it would like to monitor, negotiate and fight with. A logical unit of a union may be voluntary traders coming from a same prop/retail broker. But it can grow virtually unlimited larger. Sure, there are many different interest of members, like small traders vs. large traders, scalpers vs. momentum/swing traders. But I am sure there must be some common interests as the base to unite traders in some degree. The thought is a work in progress. Any opinion is highly appreciated. Thanks.
