No really. Think about it, do you think any ECN will accept your micro-lot ? if no one wants it how does it get filled then ? it gets filled because the broker takes it. He knows 85% of the trades will be losers so if he takes the other side, he will have an 85% win/lose ratio

secondly the platform is in the complete control of the broker. There is no such thing as "regulation" is the forex market. Let's look at share prices, for instance. If the price of say 1 lot of PBB is say $15.10, it will be $15.10 with every share broker in the country. That is what regulation means. This ensures a level playing field for everyone. If you look at forex prices, you can see that for the same cross, there are tons of prices, all of them different

why do you think that happens ?

it's because there is no regulation. Even if they say they are "regulated" by whoever, it just means that they are registered. The authority knows who they are, so they can't close shop and run away. It doesn't mean that they won't go bankrupt, it doesn't mean that they can't put an unauthorized trade on your account, it doesn't mean that they will honor your stop, it doesn't mean that they won't raise the spread to 500 pips during news time. It doesn't mean that a sudden glitch in their charts won't lead to your making the wrong decision. How do you prove that you never made that trade ?
Which brings me to that very interesting point that a lot of these forex trainers use, that you're participating in a very liquid market. It's true that forex is a very liquid market, it's just not true that you're in it

if you're in it, then no matter what broker you use, they should all have the same prices, right ?

why don't they, then ?

hm..if i'm not mistaken, brokers (e.g. fxcm, odl, etc) get their profits through spread, just like those "registered" money changers. Regulated broker (if not mistaken again) is just being registered through a body (basically they need a large sum of money). Basically, brokers has nothing to lose. Either traders profit or lose in their trades, brokers still gain, cause they're profitting through the spreads that are applied. With the margin required, it will safeguard the broker, and sometimes the traders, preventing from being in debt.
