Some firms like EchoTrade and Bright Trading require a series 7, that usually takes about 3 months to study for and the firm has to sponsor you to take it.
Other firms, like almost all of them that I have listed on my page, do not require a series 7, and as long as you put up a "security deposit" you can trade with them.
Barriers to start trading are very low. You can learn how to trade if you join a good firm, by just trading small and taking your time, and don't abuse buying power and try your best to learn and stay dedicated.
You could probably get set-up at a firm in less than 2 weeks (although lately it's taking me so long to get negotiations going between firms)
It's risky to trade at a prop firm though. If you have 20 to 1 buying power and you lose 20k on that trade, you will be responsible for it. So that is why you have to be able to stay in control of yoruself when you day-trade at a firm.
Just think of prop firms this way:
They loan you money to trade equities. You are required to put up a security deposit incase you lose money of theirs. All profits you make (at most firms) you will keep. Losses will come out of your security deposit. The firm will send you a check at the end of the month for all the profits you made. And you do it over and over again basically.
If I'm trading 500 shares of a stock, I'm aiming to not let it go against me 5 cents or $25. But aiming for the stock to go maybe 10 cents in my favor or gain $50. Stuff like that.
You control your risk. If you join a prop firm you set a limit to how much you can lose in a day before you stop (some firms have this ability set into the software to cut you off if you are performing badly) and you trade. No PDT rule to deal with.
It does have it's risks, but a good amount of the successful traders on ET are probably at firms trading.
That's why I ask what style of trading do you think you'd want to do.
Would you want to place a trade once a day and essentially swing trade. Hold equities overnight? Or would you be making a few trades a day, more intra-day swing style . Or would you be making many trades a day and want to keep your risk low but make more trades to try and gain profits.
Cy Group Trading has advertised that they don't really care how often you trade, plus I have a friend that trades their, and the firm seems awesome, because they cover the software fees as well. I don't personally have any experience with them, but I think it's a pretty safe firm to join.
But there are a ton of options, and it just depends on your style, how often you want to trade, and if you are willing to take the risk and accept the fact that it is estimated that 90% or more that attempt to day-trade for a living just can not do it. So it's probably better to trade at a prop firm and lose 1 or 2k instead of funding a 30k account and blowing all that instead. Although losing the 30k might have a better lesson behind it, the financial blow might not be worth it
