Quote from DHOHHI:
I really don't think it's tougher today. I started in 1996. Back then we had 1/8 and even 1/4 spreads. Commissions were $25 each way minimum. More with ISLD, INCA, other ECN charges. If I made a teenie on 1000 I netted about $10. Today I'd net closer to $50 on the same trade. Commissions today are minimal, next to nothing.
Sure, I've learned a lot in that time which has helped me. But if one is willing to adapt to what's facing them they can continue to succeed as a trader. Some burn out. Others aren't motivated enough. Still others never had adequate trading capital. Many reasons people leave trading.
