6. Different things suit different people

This is the most important thing. There are people profitable with most concepts and a ton of people who aren't. What's the difference? The person itself.

Psychology, how thorough they've backtested it and often times just experience. The person descibing a strategy has seen 1000s of instances of the strategy and might intuitively apply things that are not in the written strategy. A new trader is going to struggle with it unless the time and work is put in.

Indicators aren't a waste of time. Using them wrong is.

The real issue is that most traders stack 5 indicators on a chart, get conflicting signals, and then blame the indicators. One well-chosen indicator used correctly beats five used randomly.

The other problem nobody talks about: repainting. Half the indicators people use on MT4/MT5 recalculate on the current bar. They look perfect in hindsight but give different signals in real-time. If you've ever wondered why your indicator "worked on the chart" but failed in live trading, that's probably why.

Simple test: does your indicator use close or close[1]? If it uses close (current bar), it's seeing the final bar value in backtesting but only partial data in live. That gap alone accounts for a lot of "indicators don't work" frustration.

the only indicatior that I have ever seen on a professional traders chart that new what they were doing .. is volume and a moving average . I have seen traders playing professional traders using the money flow index , volatility bands , and an indicator the measures the pull back in wave 4 in a Elliot wave pattern .

@visualbacktester,

This is one of the most underappreciated points in indicator development, and you nailed it.

That close vs close[1] gap is the single biggest source of look-ahead bias in backtesting. In hindsight, close gives you the completed bar. In real-time, it gives you a moving target that changes with every tick until the bar closes. Your backtest sees a finished painting, your live chart sees a work in progress.

Worth noting: not all repainting is equal. There are roughly three types:

• Normal recalculation -- Any indicator using the current bar's close or ATR will update as the bar forms. This is expected behavior, not a flaw.
• Historical shifting -- Indicators that move their past plotted values after the fact. This is misleading and makes backtests unreliable.
• Future leak -- Indicators that use data from future bars to calculate past signals. These are the worst offenders and will always look perfect in hindsight.

A practical diagnostic: run your strategy twice -- once calculating on bar close only, once on every tick. If the results differ significantly, you've got a repainting problem.

Platform choice matters here too. NinjaTrader has a dedicated OnBarClose calculation mode that forces indicators to wait for bar completion before calculating -- a platform-level solution to exactly this problem.

Big Mike started a thread years ago specifically cataloging confirmed indicators that do not repaint -- still a solid reference worth bookmarking:

Confirmed Indicators that do not repaint I know many of you are wondering how to know for sure if an indicator repaints the past or not. So I propose we update this thread with indicators that we know for a fact do not repaint, and under what conditions that is true. What is repainting? Repainting …

Good post. The traders who understand why an indicator behaves differently live vs historical are the ones who actually get value from them.
