The short answer
An exchange-traded market is a central venue where buyers and sellers meet under the same rules. Every order goes into a shared order book, and a clearing house guarantees settlement. Stocks on the Pakistan Stock Exchange and futures on PMEX trade this way.
An over-the-counter (OTC) market has no central venue. Trades are agreed directly between the parties, usually a dealer and a client. Spot forex and CFDs trade OTC.
The differences that matter for a trader are price discovery, transparency and counterparty.

OTC market meaning
"Over the counter" originally meant buying a security directly from a dealer's desk instead of on an exchange floor. Today it means any market where trades are negotiated bilaterally, between the two parties only.
Over the counter forex is a network of banks, dealers and brokers quoting prices to each other and to clients. No single price is "the" EUR/USD price. Each dealer shows its own bid and ask, the prices at which it will buy from you and sell to you. See how forex works and bid and ask.
A CFD (contract for difference) is a contract with your broker that pays the change in an asset's price. You do not own the asset. The contract exists only between you and the broker, so it is OTC even when the underlying asset, such as a share or index, trades on an exchange. See what is a CFD.
Exchange-traded market
On an exchange, all participants send orders to the same central limit order book. Orders match by price, then by time. The exchange publishes the last traded price, volume and usually market depth, meaning the queued orders at each price level.
After a trade, a central counterparty (CCP) steps in through novation. It becomes the buyer to every seller and the seller to every buyer. Members post margin with the CCP, so if one side defaults, the CCP covers the obligation.
Price discovery
- Exchange: the price comes from the matching of all visible orders. Everyone trades on the same book.
- OTC: each dealer sets a price from its own view of the interbank market, its liquidity providers and its own risk. Your broker's quote may differ slightly from another broker's quote at the same moment. How the broker sources and fills prices depends on its execution model.
Transparency
| Feature | Exchange-traded | OTC (forex, CFDs) |
|---|---|---|
| Order book | Central and shared | Each dealer's own |
| Volume data | Published by the exchange | No consolidated figure; only estimates |
| Last trade price | Public | Visible only to the parties |
| Trading rules | Exchange rulebook, same for all | Broker's client agreement |
| Price you see | Same for all participants | Your dealer's quote |
The "volume" shown in an OTC trading platform usually counts price updates (tick volume) from that feed. It is not total market volume.
Counterparty
- Exchange: your trade is cleared by the CCP. Your main exposure is to your licensed broker, which holds your account.
- OTC: your counterparty is the dealer or broker. If it fails, there is no clearing house standing behind the trade. Your protection depends on the broker's regulation, how it holds client money, and the law of the country where it is licensed.
This is why regulation matters more in OTC markets. See regulation and safety.
What this means in Pakistan
Securities and Exchange Commission of Pakistan (SECP), with trading in listed securities and commodities only via SECP-licensed securities and futures brokers. Per the SECP, lists of licensed brokers are on the PSX and PMEX websites.
For OTC forex and CFDs offered from abroad, the regulators have taken a clear position:
- Per the SECP, offshore forex/CFD platforms operate without regulatory approval in Pakistan.
- Per the SECP, offshore platforms have no Pakistani licence or oversight and offer no legal protection or recourse.
- On residents and offshore products: per the SBP, the purchase of offshore forex/margin/CFD products by Pakistani residents violates section 4(1) of FERA 1947.
- On payments: per the SBP, remitting foreign exchange to overseas forex/margin/CFD platforms is not allowed through any payment channel (FERA s.5(1)).
Read law and regulators before opening any account. For the local exchange route, see PSX basics.
Risk in both market types
Leveraged CFD and forex trading can lose money fast, sometimes more quickly than you can react. Exchanges do not remove market risk either. Prices can gap, and liquidity can disappear. What exchanges change is how prices form, what you can see and who guarantees the trade. See why traders lose.
Frequent questions
Is forex traded on an exchange?
Spot forex is traded OTC. Currency futures do trade on exchanges, with a central order book and clearing.
Are CFDs on shares exchange-traded?
No. The share may be listed, but the CFD is a private contract between you and the broker.
Which is safer, OTC or exchange?
An exchange adds central clearing and public prices, which reduces counterparty risk. Market losses can happen in both.
Why does my broker's price differ from another broker's?
In an OTC market each dealer quotes its own price and spread, so small differences are normal.
