IB or FCM?

There are a lot of misconceptions as to what the difference is between an IB (Introducing Broker) and an FCM (Futures Commission Merchant) and how those differences will impact the clients trading practices.  We would like to take this time to set the record straight. 

According to the Chicago Mercantile Exchange, and FCM is defined as an individual, association, partnership, corporation or trust that solicits or accepts orders for the execution of a commodity transaction on the pursuant to the rules of a futures contract market and which accept payment from or extend credit to customers.

The formal definition of an IB is a firm or person engaged in soliciting or accepting and handling orders for the purchase or sale of futures contracts, subject to the rules of a futures exchange, but not in accepting any money or securities to margin any resulting trades or contracts.  The IB is associated with a correspondent futures commission merchant and must be licensed by the CFTC.

An IB is essentially a “mini” brokerage firm that is in business for the sole purpose of soliciting accounts for an FCM.  In other words, an IB brings clients to an FCM and the FCM executes trades.   An IB doesn’t accept client money in its own name; instead all client monies are written directly to the FCM and deposited into a customer segregated fund held by the bank of the FCM.  For the most part, an IB relies on the FCM to handle operations such as customer service and technical support.  Although, a quality IB will be able to assist you in many of the day to day activities so you should always refer to your broker first and FCM second.

All customer statements and end of year tax reporting (1099’s) are issued directly from the FCM.  Without understanding what an IB and FCM are it can be confusing to look at a brokerage statement for a client that is trading with an IB.  The brokerage statement will have the name, and most likely the logo, of the FCM but will identify the IB in small text usually subsequent to the text "Business Introduced By". 

Understandably so, people assume that they have an account with the FCM when in reality they have an account with an IB that clears trades through that particular FCM.  Once again, any issues or questions should be addressed with your broker, the IB, first.  Only after you are unsatisfied with your broker's response or resolution should you escalate your concerns to the FCM. 

Additionally, your broker may choose to change FCM’s in which trades are cleared at any time.   Unless you specifically object, your account will stay with your broker and begin clearing trades through the new FCM; insiders refer to this as a "bulk transfer".    In other words, you are the client of the IB’s not the FCM unless of course you would like to change brokers. 

You may often hear brokers that are working directly for FCM’s insinuate that because they are clearing members of the exchange they can provide clients with more efficient fills.  Perhaps several years ago this was in some views accurate.  However, as online trade execution has become predominant this statement is no longer valid.  If you place an order to buy a mini-sized Dow at the market through an IB and through an FCM simultaneously there will likely be very little if any difference in the fill.  In fact, if there is a difference it is may likely due to your inability to trigger the execution simultaneously.   

Another myth regarding IB’s is that they aren’t capable of offering competitive commission rates.  An IB is essentially a “middle man” to the client and the FCM.  On the surface, relatively higher commission charged by an IB seems to be logical.  After all, there is an extra hand in the cookie jar.  First the FCM must be paid for executing and clearing the trade, then the IB must be paid for services rendered. However, a further look into the details reveals that IB’s may have the ability to offer lower transaction costs than many FCM’s.

This is largely in part to the common business practice of FCM's allowing full service brokers to set their own commission schedules within pre-approved boundaries and the fact that the commission payout to a broker working for an FCM is often far less than that of a broker that is either an IB or working for an IB.  In theory, the increased exposure and name recognition of being employed by an FCM will far outweigh the difference in payout but that is an argument that is well beyond the scope of this article and likely your interest.  In reality, brokers that receive a higher percentage of the commission charged are able to "afford" to offer lower rates to customers.  Thus, you may find that many IB's are very competitive in terms of transaction costs. 

In my opinion, there are no benefits to trading with an IB over an FCM or vice versa.  The true value is in finding a broker that meets your individual needs and will handle your account efficiently.

Discount or Full Service Specialization

There are firms that offer a blended array of services and others that specialize in either full service or online discount.  Being honest with yourself regarding your skill level, market knowledge,  your needs and your trading style is a must for choosing the type of brokerage firm.  If you don’t know yourself, how could you possibly be able to choose what services are best for you?

Once you have determined what it is that you are looking for, there are a few things that you should keep in mind.   Based on my observations, it seems like as you move down the commission scale (from high rates to low rates) the adage “you get what you pay for” becomes more and more appropriate.   In other words, don’t expect unrealistic service or trading results simply because you are with a firm that is charging $100 per round turn.  On the other hand, if you are paying 99 cents per side you will likely get what you pay for which is very little service.    That may not be a bad thing if you are an experienced trader with adequate knowledge of the trading platform that you are using to execute trades and have reliable technology at your fingertips.  If you don’t fit into this category, I strongly suggest that you seek services that may be a little more expensive in terms of commission but much cheaper in terms of trading mishaps. 

Imagine inadvertently entering a highly illiquid market and experiencing trouble offsetting your trade (exchanges will reject market orders if there isn't anyone to take the other side of your trade).  A deep discount brokerage is often staffed with less than experience brokers who may not have the knowledge or exchange contacts to help you through your predicament.   Similarly, what if your internet connection fails and you find yourself on hold waiting for a representative of a deep discount brokerage firm while the market may be going wildly against your position.  These are somewhat extreme circumstances and are not everyday occurrences but what I am trying to point out is that it may be worth paying slightly more in commission than "paying" far more in market losses.

Blanket Commission Structure or Variable

As a retail account you must understand that while all brokerage firms want business, each client account opened poses a significant risk.  This is due to the fact that in futures and short option trading it is possible to lose more money than is deposited in the account.  A negative account balance is psychologically devastating to a trader but is equally as stressful to a brokerage firm.  The brokerage firm is expected to cover any negative balance with the exchange immediately and believe it or not your individual broker is expected to cover your negative account balance with her commissions prior to you bringing the account whole again.  With this known, it is easy to see that any commission charged is partly attributable to the risk of a negative account that the firm is facing by taking you as a client.    Accordingly, clients that are deemed to be a relatively higher risk to a broker or brokerage firm will likely be charged a higher commission accordingly.  As with any other industry, risk are reward are highly correlated.  Thus, although a brokerage firm’s primary business is executing trades they must also think like an insurance company.

Insurance companies collect your personal data and characteristics in order to accurately assess the risk of issuing a policy and determining a premium accordingly.  Such a system ensures that each policy holder is paying for the coverage rendered, nothing more or nothing less.  Without such categorization, blanket premiums would be levied causing those with low risks of a claim to subsidize those with high risks of a claim.  For example, an avid smoker would be paying the same amount of money as an avid jogger for a health insurance policy with identical coverage.  The smoker would be paying less than he should be relative to the potential risk to the insurer, while the jogger would be paying more than he should to compensate the insurer for coverage.  This approach is clearly ineffective in rewarding positive behavior, consequently insurance firms use customer profiles to prevent such imbalances from occurring.

Efficient brokerage firms may look to the same logic when determining commission schedules.  While the determining characteristics aren’t quite as definable as they may be in regards to insurance, there are definite factors that should be considered in the amount of commission charged.  One of those factors is account size.  All else being equal, a trader with a large account poses less risk and is more valuable than a trader with a relatively small account.  Therefore, in most circumstances a trader with a larger account deserves a lower commission rate than one with a smaller account. 

Another component to determining commission should be trading style.  This is often something that may  be determined after the account has been open and trading.  For instance, a trader that has a well funded account and typically uses approximately half of the available margin on a given day is a relatively low risk client.  On the other hand, a trader that is constantly pushing the limits in terms of margin poses a substantial amount of risk to a trading firm. 

Understanding these basic concepts of commission and how brokerage firms assess risk it should be obvious that in most cases it is preferable to trade with a firm that offers a flexible rather than a fixed commission structure.

Trading Platforms

If you are a position trading using options or futures, trading platforms shouldn’t be a high priority.  For position traders, simply having the means of easily placing trades and monitoring the account is sufficient.  There is no need to complicate things unnecessarily. 

On the contrary, if you are scalping, or any other form of day trading, the front end platform that you will be using to enter trades becomes very important.  Not only must the platform be quick as well as easy to use and understand, it can’t be so quick and easy that mistakes are highly probable.  If you are a day trader you are most likely following products that are executed electronically.  If this is the case, most platforms are offered in live demo versions in which you can determine which is preferable to your needs. 

Floor Presence

Insiders often refer to a clearing FCM as having “floor presence”.  This means that they own a seat on the exchange and clear their own trades.  In theory, because they are privy to the action they may be able to provide clients with better execution.  However, the execution of electronic contracts will provide very similar results regardless of whether you are trading with a firm that is a member of an exchange.  Whether a firm does or doesn’t have a floor presence only comes into play should the client be trading open outcry products. 

For those that are trading open outcry options or option spreads I recommend using a full service broker that is experienced in this type of trading.  A broker that handles a lot of option business will have contacts on the trading floor that will be happy to execute trades for a small fee, often referred to as a give up fee.  Using a give up broker is preferable in many cases whether the firm  has a floor presence or not.  Thus, trading through give up brokers eliminates any benefit that a trading firm being a member of the exchange will bring.  Simply put, your execution may rely on the individual broker handling your full service account than the brokerage firm she works for.

Customer Service

Clearly, a customer service department is there to make your life easier.  They should be well informed of all back office issues and capable of meeting your needs in a timely manner.   Unfortunately, it is very difficult to determine whether or not a customer service department is efficient until after your account has been open long enough to experience its capabilities.  However, prior to opening an account you may want to browse the internet forums and message boards for ratings of the prospective brokerage.  Keep in mind, that if you are looking to trade with an IB you should be looking for information on the customer service department of the FCM not the IB.  Although, you will be primarily in contact with your IB and you should have a good idea of what type of service they are capable of offering.

Tech Support

With the growing popularity of online trading it is imperative that the firm that you choose have a well staffed and knowledgeable technical support staff.  Without it, you may find yourself in a very frustrating situation.  Imagine entering a market just before your trading platform “crashes”.  It is true that you would be able to quickly call your broker to offset the trade, nonetheless you would want immediate resolution to your issue.  It is difficult enough to make money in the markets, the last thing that you need is technical trouble and frustration over poor technical support. 

You may want to go as far as to ask your prospective firm approximately how many people make up the their tech support staff.  The answer may be surprising.  I have known relatively large firms to have two member technical support departments.  Depending on the size of the firm, this may not be enough to service the needs of the firm and may result in long hold times. 

In Conclusion

Your ultimate experience may be determined in large part by the individual broker that is handling your account.  Likewise, an experienced broker will be capable of delivering efficient execution and excellent service regardless of whether or not they are working for an IB or FCM.   With that said, when picking a firm to execute your trades and handle your account, cutting corners isn't an option.  Although it isn't' as fulfilling, you should be researching brokerage firms  and prospective brokers nearly as much as you research the markets.

Full Service or Online?

The decision to trade online or through a full service broker will undoubtedly make a large impact on your bottom line.  However, the impact may or may not be what you had in mind.  If you aren’t ready to begin placing your orders online on your own, despite saving money on commission it may be the most costly mistake that you ever make.

While commission is baggage, a slightly higher rate it may be worth every penny assuming that your broker is truly giving you what you are paying for…reliable and efficient execution along with quality guidance in strategy and analysis.


Choosing a Commodity Broker

Most traders that are in the market for a broker are concerned primarily with trading platforms, commission and the quality of information provided such as newsletters.  However, if you are in the market for a full service broker, you need to take your research one step further.  Not only do you need to find a firm that is capable of meeting your logistic needs, but it is crucial that you choose an individual broker in which you can properly communicate, are comfortable with their experience and most of all trust to help you on your journey to being a successful trader. 



Choosing a Brokerage Firm

Deciding on a brokerage firm is a significant decision and shouldn’t be taken lightly.  Before committing to a firm it is imperative that you research their services, experience, trading platforms and commission structure but more importantly whether your trading style and personality will be compatible.   For example, a beginning trader shouldn’t look to a deep discount online brokerage firm simply because they likely won’t get the guidance that they will need as a novice.  Similarly, a seasoned trader wouldn’t want to choose a firm that focuses on high-end service with a hefty price tag.
