My opinion. Do it. But don't open your account with 1000.00. Expect, FULLY EXPECT to LOSE everything you deposit. So if you only have 1000.00, you should deposit 50 bucks with Oanda into a MICRO account. That way you can trade LIVE, not DEMO from the get go and risk a minimal amount of money. You screw up and lose it all, you get to start over again 20x's. If you can take the 50.00 to 100.00 consider repeating that a couple times before you can even consider putting any money up front.
People always say you need a lot of capital to start. I disagree on the basis that if you TRULY know what you're doing and are consistently successful you should be able to grow any amount of money into any amount of money. The difference is starting small requires MUCH MUCH MUCH more discipline and consistency over the long run to make any appreciable growth.
You don't need 20k to start if you are a consistently profitable trader. Its not about the capital in my opinion, its about the consistency. Does more capital = more "buffer" room before your out looking for a job again? Sure. But you don't need to 20k to buffer your losses if you're already good enough not to make them. And if you're not good enough to not make them then you've got no purpose to be trading with 20k in your trading account.
Deposit 50 bucks. Learn. Lose due to YOU (not your method) screwing up. Repeat until step 3 is absent. Go from there.
Just don't DEMO. There is so much talk about demo trading, we tell everyone new to trading to DEMO DEMO DEMO. Then they do with their 50k practice account, they make 2-3k a day and think they got it all figured out and the Ferrari is gonna be in the garage by the end of the month. Then they go live with their 5k and its wiped from their account faster than they can say "I Don't know what the hell i'm doing". Much of this is due to the psychological aspects of trading, fear of loss, greed, anger, all of it. And it surfaces as soon as you put real money on the line. So what you need to do is never take the easy route and Demo. Use live money from day one so your actions ALWAYS have a consequence and you don't get to write off stupidity as "oh, well at least it was only a demo account".
Go out and buy Trading in the Zone by
Mark Douglas. Read it twice before you place a trade. It would've saved me thousands if I had read it prior to trading. It is all about the psychological / emotional aspect of trading. That is what will be the hardest thing for 99% of trading to master. A trading method is easy. Pulling the trigger, managing a trade without emotion, and taking profit without fear or greed entering into the equation is the hard part.
Hope this helps!
