Are Conventional Technical Indicators the Real Reason Retail Traders Fail?

I’ve been sitting with this thought for a while now.

If 9 out of 10 retail traders are failing, especially in intraday trading, there has to be a common denominator. It’s unlikely that millions of people are independently making unique mistakes. More likely, they’re all being guided by the same tools, frameworks, and assumptions.

And that’s where I think conventional technical indicators come in.

Recently, one of the broking apps rolled out an AI-powered real-time analysis feature. Naturally, I was excited. This felt like a step into the future. But as I dug deeper, the excitement faded quickly.

Under the hood, it was the same old recipe:

  • ADX

  • SMA

  • A mix of familiar indicators that retail traders have relied on for decades

Just wrapped in an “AI” label.

That raised a serious question for me:

If these indicators couldn’t change the outcome for retail traders over the last hundreds of years, how will adding AI on top of them suddenly flip the 9-out-of-10 failure ratio?

It feels like AI is being chained to outdated assumptions.

What really pushed this thought further was a video I watched recently. A car owner had an engine problem. They recorded the engine sound and fed it to ChatGPT in real time. Without opening the engine, the AI identified the issue accurately and even helped them order the correct spare part.

That’s powerful.

It didn’t rely on a checklist of “if sound A then issue B.”
It recognized patterns directly from raw data.

So here’s the question I keep coming back to:

Will AI ever be liberated from the boundaries of conventional technical indicators—the very tools that failed to help 9 out of 10 retail traders for generations?

Or will we keep repackaging the same rusted concepts with newer buzzwords?

I’m curious what others here think.
Is the problem really the trader—or the tools we’ve been teaching them to trust?

Trading desks like Jane Street hire mathematicians and statisticians to design full trading systems grounded in probability, risk, and market structure, while retail traders are largely offered indicators built by software developers that focus more on signals than on statistical edge.

This creates a quiet conundrum: the professionals compete with models that understand uncertainty, distribution, and execution, while individuals are encouraged to trade with simplified tools that often mask those realities.

It raises an uncomfortable question about whether the real divide in markets is not access to information, but access to the way of thinking that turns information into a durable edge.

I think there’s a valid point about misuse of indicators, but I don’t agree that conventional technical indicators are the reason retail traders fail.

That conclusion mixes up correlation with causation.

Retail traders failed long before modern indicators existed and continue to fail even when they abandon them. The constant factor isn’t the tool — it’s behavior, risk management, and expectations.

Indicators don’t place trades. Traders do. The same indicator used with proper position sizing, context, and discipline can produce very different outcomes. If indicators themselves caused failure, then institutional and systematic traders — many of whom still use momentum, volatility, and trend measures (just expressed differently) — would fail too.

Indicators were never meant to predict; they’re probability filters. When traders treat them like certainties or shortcuts, failure is expected — but that’s misuse, not proof the tools are broken.

Removing indicators or adding AI doesn’t fix the real issues:
overtrading, poor risk control, lack of testing, and emotional decision-making.

In my view, indicators aren’t obsolete — they’re often misunderstood and scapegoated for deeper structural problems in how retail traders approach markets.

So, to the title of the post:

Indicators aren’t and won’t be obsolete. They’re just misunderstood and are misaligned.

Self is almost always the reason. Trading is a holistic process that is much more than simple buy and sell. AI or No AI technical indicators are just mathematical formulas or models that takes in market data and gives an output that helps in getting better insights into the raw data. All the money I made from trading is using technical indicators and hard market data only.
