What Is Straight Through Processing (STP)?

Published on: 2025-11-06

Straight Through Processing (STP) brokers send trades directly to the real market with no middleman, no delays, just transparent execution. 


Introduction

Straight Through Processing (STP) is a trading model used by brokers to send your orders directly to the real market without any manual interference. In this system, there’s no dealing desk, meaning the broker doesn’t trade against you or decide your prices.


Instead, your order is passed automatically to large financial institutions called liquidity providers, such as banks or other brokers, who actually fill the trade. 


Definition

Straight Through Processing STP

Straight Through Processing (STP) means a broker uses technology to route client trades directly to liquidity providers for execution, without any dealer or manual control.


STP brokers act as a bridge between the trader and the market. When you place a buy or sell order, it’s automatically matched with the best available price from banks or institutions connected to the broker’s system.


The broker doesn’t profit from your loss, instead, they earn a small fee through a spread markup (a few pips added to the market price) or a small commission per trade.


How Straight Through Processing Works

When you place an order, the STP system automatically scans prices from several liquidity providers to find the best bid and ask rates available.


  1. You place an order to buy or sell.

  2. The STP system sends the order to its network of liquidity providers.

  3. Each provider returns a bid and ask price.

  4. The system picks the best available price for your side.

  5. The trade executes at that price and you get a confirmation.

  6. Everything happens electronically and in milliseconds. 


Because the broker isn’t manually involved, this method reduces delays, slippage, and price manipulation.


Example

Suppose a trader wants to buy GBP/USD using an STP broker. When the trader clicks “Buy,” the broker’s system instantly sends that order through to its connected liquidity providers such as major banks or financial institutions offering live prices.


If one provider quotes 1.2502, the trade is executed immediately at that rate. The broker doesn’t hold the trade or take the other side; it simply “passes through” the order and earns a tiny commission or markup (for example, 0.1 to 0.3 pips).


This is Straight Through Processing (STP) and it ensures the trade goes directly to the market without human interference, delays, or price manipulation. 


It’s faster, fairer, and ideal for traders who want transparent execution.

Why Straight Through Processing Matters

STP brokers give traders access to real market conditions without the broker taking the other side of their trade. This means less conflict of interest and better transparency.


The model is especially useful for scalpers, algorithmic traders, and professionals who rely on fast execution. However, it also benefits beginners who want fair access to live market prices without hidden manipulation or delays.
