How Forex Trading Has Changed: From Trading Floors to AI Algorithms

Forex trading wasn't always available at the click of a button like it is today. Previously, people had to talk and negotiate to complete a transaction; there was no electronic trading. Today, conducting transactions electronically makes trading much more efficient, providing 24/7 access and increasing liquidity, as well as facilitating faster entry and exit from a position.

Justin Grossbard, currency trader and co-founder of CompareForexBrokers, describes the change:

“We’ve moved from an era of noisy trading floors to quiet offices, where trades are executed instantly with little human interaction. Yet, the markets are 'noisier' than ever, given that more and more traders are able to access the same markets directly from their bedrooms.”

Grossbard concludes on the topic: "The digital shift has also made markets more liquid, as well as cheaper to operate in and faster to place orders, which I consider a very positive point for traders."

Trading rooms and voice brokers

Initially, trading in the foreign exchange market was restricted and only available to institutions, before leverage became available to retail traders. Transactions were carried out in whole lots, meaning that the value of each transaction was always at least US$100.000, something unthinkable for most traders.

It was also necessary to have internet connections to take advantage of the best prices, which were already inaccessible, creating another barrier to entry for traders. Nor were there any technical analysis tools or platforms offered; everything was done in person or by phone.

Electronic trading has given rise to independent traders.

Operating electronically created a huge wave of opportunity, connecting all institutions to retail traders for the first time. This transformation changed the dynamics of the market, as it no longer mattered just who you knew, but how quickly you could act. 

Real-time prices are now sent to your trading terminal, and brokers can execute their trades instantly thanks to the connection offered with liquidity providers.

Currently, best forex brokers They also provide electronic trading platforms to execute trades directly, reducing the need to call the broker to place an order.

Automated algorithmic trading strategies

Finally, the next phase involved computer scientists developing algorithmic strategies using computer code and mathematics to search for alpha in the markets. Now, by using popular languages ​​like Python or C#, it's possible to code your trading instructions and automate every aspect of the operation.

The algorithm's speed allows it to process information instantly and it can be applied across multiple markets simultaneously without a drop in performance. This has also opened up opportunities for high-frequency trading (HFT), where it's possible to profit daily by exploiting small market movements.

The best forex companies in Brazil offer platforms such as MetaTrader 4, MT5, or cTrader, all of which provide automated trading tools for retail traders.

AI integrated with machine learning for more efficient operations.

Currently, with AI tools from OpenAI and Anthropic, traders are creating tailored language models (LLMs) to operate according to their behaviors. These artificial intelligences can reason about current market conditions and recent announcements to adjust the strategy to the type of environment in which they are operating.

Advanced programmers can combine AI with machine learning to continuously analyze and evaluate ways to improve strategies. This autonomous feedback loop ensures a competitive advantage, considering that AI can process petabytes of data in real time and generate precise signals at speeds far exceeding human capabilities.
