Quote from scot.mcpherson:
Well there is one barrier. You need money. Anyone with half a brain knows that if you want to "Trade" rather than "invest", you need enough capital to surmount commisions and fees on trades. I'd say you want to target 1% or less in commisions and fees to make it worth while. More commissions and you are fighting your profits with the costs to do business. In most cases for bargain trading brokers, that's about $1000 per trade ($10 commissions and fees). Everyone can save $1000 in a couple month, I don't care who you are, but it requires you do put that money away and not think of it as backup money for something you will need or want. Its gone....
If I can do a trade and cover my commissions and increase my yield and capital, that will make me happy for now. I'd "daytrade" later when I have enough capital to produce an income from it without hurting my growth.
Beyond having initial capital, yes no barrier....
You need far more capital to make good money investing than by trading...
