Interesting discussion about margin = risk. I never agreed with the argument. %risked / pip stop / 10$ (100k contract/pip value) gives the necessary contracts per individual risk tolerance (assuming you don't trade around news). Margin really has no bearing on the issue. Personally, I trade with ultra tight stops and need high leverage to make my strategy fly (nothing higher than 1%). Tight stops = higher risk might be the only argument against offering high leverage. But that decision should really be left to the traders discretion and not some arbitrary determination by brokers playing big brother. This is an adults game. If fools rush in, what concern is that of traders? None, really - assuming you're not pulling the trigger.
Retail Forex Brokers Retail forex brokers or market makers handle a minute fraction of the total volume of the foreign exchange market. According to CNN, one retail broker estimates retail volume at $25-50 billion daily, [2]which is about 2% of the whole market. CNN also quotes an official of the National Futures Association "Retail forex trading has increased dramatically over the past few years. Unfortunately, the amount of forex fraud has also increased dramatically." All firms offering foreign exchange trading online are either market makers or facilitate the placing of trades with market makers. In the retail forex industry market makers often have two separate trading desks- one that actually trades foreign exchange (which determines the firm's own net position in the market, serving as both a proprietary trading desk and a means of offsetting client trades on the interbank market) and one used for off-exchange trading with retail customers (called the "dealing desk" or "trading desk"). Many retail FX market makers claim to "offset" clients' trades on the interbank market (that is, with other larger market makers), e.g. after buying from the client, they sell to a bank. Nevertheless, the large majority of retail currency speculators are novices and who lose money [3], so that the market makers would be giving up large profits by offsetting. Offsetting does occur, but only when the market maker judges its clients' net position as being very risky. The dealing desk operates much like the currency exchange counter at a bank. Interbank exchange rates, which are displayed at the dealing desk, are adjusted to incorporate spreads (so that the market maker will make a profit) before they are displayed to retail customers. Prices shown by the market maker do not neccesarily reflect interbank market rates. Arbitrage opportunities may exist, but retail market makers are efficient at removing arbitrageurs from their systems or limiting their trades. A limited number of retail forex brokers offer consumers direct access to the interbank forex market. But most do not because of the limited number of clearing banks willing to process small orders. More importantly, the dealing desk model can be far more profitable, as a large portion of retail traders' losses are directly turned into market maker profits. While the income of a marketmaker that offsets trades or a broker that facilitates transactions is limited to transaction fees (commissions), dealing desk brokers can generate income in a variety of ways because they not only control the trading process, they also control pricing which they can skew at any time to maximize profits. The rules of the game in trading FX are highly disadvantageous for retail speculators. Most retail speculators in FX lack trading experience and and capital (account minimums at some firms are as low as 250-500 USD). Large minimum position sizes, which on most retail platforms ranges from $10,000 to $100,000, force small traders to take imprudently large positions using extremely high leverage. Professional forex traders rarely use more than 10:1 leverage, yet many retail Forex firms default client accounts to 100:1 or even 200:1, without disclosing that this is highly unusual for currency traders. This drastically increases the risk of a margin call (which, if the speculator's trade is not offset, is pure profit for the market maker). According to the Wall Street Journal (Currency Markets Draw Speculation, Fraud July 26, 2005) "Even people running the trading shops warn clients against trying to time the market. 'If 15% of day traders are profitable,' says Drew Niv, chief executive of FXCM, 'I'd be surprised.' " [4] In the US, "it is unlawful to offer foreign currency futures and option contracts to retail customers unless the offeror is a regulated financial entity" according to the Commodity Futures Trading Commission [5]. Legitimate retail brokers serving traders in the U.S. are most often registered with the CFTC as "futures commission merchants" (FCMs) and are members of the National Futures Association (NFA). Potential clients can check the broker's FCM status at the NFA. Retail forex brokers are much less regulated than stock brokers and there is no protection similar to that from the Securities Investor Protection Corporation. The CFTC has noted an increase in forex scams [6].
