I do not think that there is an average payout simply because there are an EXTREMELY limited amount of firms that do that. I would say that 50% is close to a sky payout; but I do know that the 30% is the standard. But if you have a good track record (and these places dont care how many trades you do) - you may negotiate some deal, I guess.
So, what you're saying is, there aren't many firms who don't charge commissions but instead take a % of your payout? At the firms that do this, 50% would be considered a 'high payout?' Lastly, how many shares do you have to be doing a day for a firm to consider you?
1. Yes, very very few. 2. Yes - 50% with 0 commission is extremely high (it's probably as rare as paying 0.001 a share with 100% payout trading firm capital) 3. That's the point - they dont look for traders based on how many shares they trade - they are not in the business of churning. The difference between these (0 commission) firms and the rest of prop shop - the only way they make money is if the trader makes money. They don't get any money for shares traded. Therefore - if you're numbers are good (P&L) share amount is irrelevant. I know of a place that is taking on traders now, the one the original poster asked about I think. The spreadsheet posted by WCOMtrader makes a lot of sense. For a beginning trader I think that paying no commission is great.
Well, I'm thinking that 300,000 shares a month is about what I might be doing ... I don't know if you've seen my other thread (IB cheap etc), but do you think on only 300,000 shares a month that some firm will give me better commissions than 1 cent for 500 and 1/2 cent for 500+?
