I wonder how many people read that statement, and just breezed past it, without grasping the importance of it.
In order to answer the question, “How much capital is enough to start?”, you need to answer three other questions first:
(1) Do you know how to trade? As Mike (TalonD) put it: can you grow $10 into $20? And then double it again?
And again, and again, into the future?
(2) How much cash do you have for venturing into currency trading? This means cash you can lose, without affecting your life-style, without upsetting your family budget, and without causing you to lose sleep or develop an ulcer.
This is the question that Jay (Master Tang) addressed in his post.
(3) Can you adjust your trading to a size that is appropriate for the size of your account? This is the question that Mike answered (for himself) in the quote above.
To the Original Poster:
You haven’t given any indication that you know how to trade. Increasing your account by 0.5% per day doesn’t happen just because you have deposited a certain sum of money into a forex trading account. It happens because (and ONLY IF) you know how to trade. If you can’t answer question (1) with a “yes”, without any hesitation, then skip questions (2) and (3), and concentrate on training yourself to trade IN DEMO.
You have indicated that you have £2000 available for trading. Be honest with yourself, and make sure that your £2000 actually meet the criteria in question (2), and the criteria offered by Master Tang.
As for position size vs. account size, extrapolate what Mike said, to cover all of the available types of accounts:
To open a STANDARD ACCOUNT (lot size 100,000 units), $100,000 or £100000 is recommended.
To open a MINI ACCOUNT (lot size 10,000 units), $10,000 or £10000 is recommended.
To open a MICRO ACCOUNT (lot size 1,000 units), $1,000 or £1000 is recommended.
To open a NANO ACCOUNT (lot size 100 units), $100 or £100 is recommended.
To open an OANDA-type [I]non-lot[/I] account (min. trade size 1 unit), any (tiny) amount will get you started.
…and then, trade 1 lot (or 1 unit) at a time.
In other words, do as Mike does, and trade positions equal to the size of your account.
Those recommendations are strictly my own. I don’t happen to remember what the Babypips School recommends.
