I have seen a lot of people are discussing the pro. trading firms. now I will just put some of my ideas to some of the firms. First, what I want to mention is I am just talking about equity trading firms, so it is not including those option trading firms. Top firms: schonfeld securities, First New York Securities, Heartland Securities: They are top firms. Working there, you don't have to put your capital down. Absolutely, as I understand, that is meaning employment. I like that. 1) Schonfeld securities is the largest firm among all of the short term trading. It is one of the largest market maker in NYSE and NASDAQ. And it is also a top program trading company. So working there, I think that you will learn a lot. Because of the bad situation at present, they have changed some of their policy. But I think that they are still the best if you want to do prop trading. 2) FNYS and Heartland. I don't have too much to say about those two firms. But they should get respect because they give you salary although it is just during the first year. To tell the truth, I have no idea whether they are really good at this field, since I cannot find too much about them when I search their names from google or MSN. But their salary policy did give them chance to get the better quality people. But before you choose firms, don't be just lured by that. you have to check the trader quality and training program too. not top firms: worldco, ETC, generic, and so on... 1) worldco. I think that a lot of people talked about this firm on this board before. I don't personally like this firm because of its hiring policy. I had some bad experience there. But they are still not bad compared with other firms since they are seld-clearing. But most of them trade NYSE, if you want to trade NASDAQ, you will have to pay high commission... Regarding this, Schonfeld does not have this problem. 2) ETC, no capital needed. I really don't know too much. But I heard that you need sign two-year contract, which is not very good. 3) others, such as generic, Liongroup, and so on. Most of them need your capital. In my idea, this is not a real professional trading company. Anyway, this is some of my idea. I can talk more, but just want to open a new thread to get more discussion. In the future, people want to know about pro. trading firms, they can refer to this resource. Thanks.
