Why Day Traders Are Flocking to AI-Driven Stock Strategies—and What They’re Getting Wrong

Artificial Confidence, Real Risk

Retail traders in the US and UK are increasingly turning to artificial intelligence to inform or automate their trading decisions. AI-generated signals, automated chart analysis, prompt-driven trade ideas, and pre-built GPT trading bots have surged in popularity across Discord servers, Telegram groups, YouTube channels, and TradingView plugins. AI is being sold as the solution to market inconsistency, decision fatigue, and emotional mistakes. But the majority of these tools offer little more than algorithmic pattern repetition dressed in convincing language.

The problem is not that AI is being used, but that it’s being misunderstood by the users. Most day traders assume AI can “see something” they can’t. In reality, current AI models are incapable of true market prediction. They lack contextual awareness and are prone to producing confident but misleading results. The rush to apply large language models and so-called “smart bots” to day trading has created a situation where automation is increasing, but reliability is not.

“Retail traders are buying into AI signal services without any understanding of what the model does—or doesn’t do,” says Tobias Robinson, trading expert at DayTrading.com, a platform that reviews day trading tools and platforms. “In most cases, the AI isn’t predicting markets. It’s repackaging indicators in language that sounds more intelligent.”

AI is not a trading edge by default. It is a tool, and often a blunt one. The excitement around language models and trading bots has created a market filled with false certainty, exaggerated performance, and unregulated products disguised as intelligence. In the US and UK, where regulatory enforcement is starting to catch up, traders may soon see more restrictions on how AI trading services can be promoted to retail traders. Until then, the responsibility to see through the hype sits with the trader.

Misplaced Faith in Black-Box Outputs

AI trading tools, particularly those using large language models, rely on pattern recognition. They do not understand what they are doing. When asked to suggest a trade, a GPT-style (Generative Pre-trained Transformer) model will assemble a plausible-sounding response using statistical associations drawn from training data. It does not verify if the output makes sense in the current market. It does not factor in Fed announcements, earnings reports, or intraday volatility unless explicitly prompted, and even then, it may hallucinate data or misinterpret intent.

In backtested environments, many AI-powered bots perform well on historical charts, but forward performance, which is what traders actually care about, is rarely addressed with transparency. Bots are often marketed based on curve-fit strategies, simulated account performance, or heavily filtered signal results. False positives, poor position sizing, and missed reversals are hidden behind screenshots of successful trades and “98% accuracy” claims that collapse under closer inspection.

The result is a false sense of security. Traders believe they are using advanced intelligence, but in most cases, they are automating noise.

Regulatory Scrutiny

Regulators in the US and Europe have already flagged concerns. The Securities and Exchange Commission (SEC) in the US and the Financial Conduct Authority (FCA) in the UK have both issued warnings about unlicensed AI trading services, misleading performance claims, and the use of opaque algorithms in financial promotion.

Most AI signal sellers are not authorized financial advisors. They do not offer legal disclaimers, they don’t explain their methodology, and they are often hosted on platforms with no identity verification. Some operate under affiliate structures tied to offshore brokers and are deliberately set to encourage high-risk trading regardless of actual signal quality.

Despite this, adoption continues to grow, particularly among inexperienced traders looking for an edge in volatile equities, crypto, or synthetic asset markets. Trading bots using OpenAI’s GPT or custom Python wrappers are shared widely, often with no transparency around data input, version control, or risk limits. The assumption is that automation reduces emotional error. What it often does is speed up execution of bad decisions.

In March 2025, the European Securities and Markets Authority (ESMA) issued a warning over the use of AI for investing.

“There is a growing number of websites and apps that offer AI-generated trading ideas and suggestions, often in exchange for expensive monthly or yearly fees, using names such as stock picking or stock signal,” said ESMA. “AI-powered tools providing trading ideas can generate incorrect information. They may be based on outdated, incorrect or incomplete information. The accuracy of AI-generated predictions can vary significantly.”

ESMA has also raised concerns over how publicly available AI tools online can provide highly convincing and professional-sounding advice on investments, while not being subject to the same compliance standards as authorized investment advisors.

On the other side of the Atlantic, the U.S. Commodity Futures Trading Commission (CFTC) is warning about how scammers are using the public interest in AI to sell trading schemes that promise unrealistic or guaranteed returns.

“Fraudsters are exploiting public interest in artificial intelligence (AI) to tout automated trading algorithms, trade signal strategies, and crypto-asset trading schemes that promise unreasonably high or guaranteed returns”, the CFTC said in an officialcustomer advisory headlined “AI Won’t Turn Trading Bots into Money Machines”.

This CFTC advisory is not only a warning about the short-comings of AI in itself when it comes to accurately predicting future market movements; it is also a warning about how scammers world wide are now capitalizing on the buzz word “AI” to make their get-rich-quick schemes sound more credible.In their advisory, the CFTC highlights a case study on “Mirror Trading International”, a ponzi scheme where the South African citizen Cornelius Johannes Steynberg stole more than $1.7 billion in bitcoin over roughly three years, using a few websites in combination with accounts on the popular social media platforms Facebook, Instagram, and YouTube. To make the scammore believable, Steynberg also created fake customer accounts and balances using MetaTrader demo accounts.

ChatGPT as Signal Source

Some traders have gone further, using ChatGPT or similar tools as direct market analysts. Prompts such as “Which stocks will go up today?” or “Generate a profitable trading strategy for scalping SPY” are used without any awareness of the model’s limitations. The AI, trained on a mixture of public content, academic material, and user-submitted prompts, generates ideas that sound professional. What many users fail to realize is that it cannot browse real-time data, perform quantitative analysis, or evaluate market structure. Its output is based on language patterns, not financial logic. In some cases, the AI even fabricates entire strategies, invents indicators out of the blue, or references trading tools that do not exist. When the trader is not knowledgeable and experienced enough to spot these issues, the risks compounds.

What Is An LLM?

Some of the AI Investment Robots promoted to retail traders online are simply LLM bots relabeled as investment robots. In artificial intelligence, LLM stands for Large Language Model, and denotes a type of AI trained on massive amounts of text to understand and generate human-like language. Gemini, Claude, and GPT-4 are all examples of LLM-style AI.

As you can see, LLM bots are based on massive amounts of text and do not have any deeper understanding of how markets move. They're called large language models because of the billions (sometimes even trillions) of parameters used to represent knowledge and patterns in language.

LLM-style AI is today commonly used for text generation, translation, summarization, and even code generation, but when we ask it to actually predict future market movements, we are asking it to do something it was not designed for. An LLM can still give you very smart sounding advice, but it is basing this on historical texts and not on any innate ability to predict future market movements.

Retail Traders Pay the Price

The biggest risk is not to the market, it’s to the individual hobby trader. Inexperienced traders relying on AI-driven tools without understanding what drives them often increase their trade frequency, over-leverage, or abandon standard risk management protocols altogether. Losses accumulate quickly when AI is used as a shortcut for skill.

In retail trading communities across Reddit, X (formerly Twitter), and Telegram, reports of blown accounts and over-automated trading systems are becoming increasingly common, but they’re often brushed off as “bad prompts” or “incorrect fine-tuning” rather than what they are: the result of handing complex decision-making to systems not built for it.

It should be noted that machine learning already plays a role behind the scenes in institutional finance, where it is involved in fields such as risk modeling, portfolio optimization, and order execution. But the retail-facing layer popular among small-scale hobby traders is a layer consisting of low-cost AI bots, language-model signal generators, and prompt-based scalping strategies, and this layer is a far cry from the expensive AI solutions utilized by institutional players. In many ways, the retail-facing robots are designed to sound smart, not to actually be smart. It is absolutely possible that the technology will improve even at the retail level at some point in the nearby future, but we are certainly not there now.

What Retail Traders Should Actually Do

For small-scale hobby traders, using AI as a supplemental tool can be helpful, e.g. for backtesting logic or exploring strategy variations. Using it to replace real analysis, price reading, or trade management is premature. No AI available to retail traders in 2025 has the capacity to evaluate a live market in context, calculate risk in real time, or adapt to economic shifts without direct human input.

Those serious about trading should treat AI like any other tool: useful when understood, dangerous when not. Anything that automates a decision also automates the risk that comes with it.
