"Isn't good forecasting coherent with good trading?" The honest answer is no. Trading — and making money from trading — is a far different ball game from merely forecasting. Even if someone could exactly predict the highs and lows of the next intermediate move over the coming week, I could not guarantee they would make money.
The Elliott Wave Principle is the only technical-analysis technique that offers a genuine long-term perspective — which contradicts the common belief that Technical Analysis works only in the short term. Most other tools are limited. Classical patterns such as the head & shoulders, rectangle or flag work only until their targets are met; after that they say nothing about the next move. Momentum indicators like RSI and MACD are price-following — they measure how overbought or oversold a market is, but they cannot forecast. With Elliott Wave, once you know where you stand in the pattern, you can map the possible moves ahead. And because the pattern is fractal in nature, the same logic applies from a one-minute chart to a one-decade view.

I was a strong propagator of this theory and used it in my trading for more than seven years. The curious part: the amount I relied on it fell every year, while my trading P&L grew. Not because it became less significant, but because I accepted its limitations — sticking to a few important rules and combining it with other tools to find better setups. What I want to focus on here is how the Elliott Wave Principle, used wrongly, can hamper your trading.
It Was Never a "Trading Technique" in the First Place
When R. N. Elliott discovered this theory in the 1930s, he was simply describing how market prices unfold in a specific pattern. He never said "buy here" or "sell there". It was an explanation of how the repetitive behaviour of market participants causes prices to trace similar patterns across time frames. A simple reading of impulse and corrective moves can reveal the larger direction of the market. Only later did people start using the theory as a trading methodology.
The "Alternate Wave Count" Gimmick
Elliott was smart. He devised a theory that is always "right", no matter where the market eventually goes. On any stock or index there are at least two — and often seven to ten — valid wave counts. So there is always at least one bullish alternate and one bearish alternate. Pick the bullish count, buy, and watch the market fall, and you lose money — but has the theory been wrong? Not at all; it had clearly flagged an alternate bearish count. Combine all the counts and some say up, some say down, some say sideways. Wonderful information: the market may go up, down, or sideways!

"The 5th Wave Is Near Completion"
Show a newcomer a chart with a rally and, invariably, they will try to fit five waves into it and announce: "We are completing the 5th wave; a correction should begin now." The 2009–2010 rally in the Sensex was a classic trap for exactly this reflex.
Even a Textbook Impulse Can Be Fully Retraced
In theory, after a clean impulse down, the corrective bounce should not exceed the start of that impulse before a new low arrives. Yet there are countless examples of impulsive moves, up and down, being fully retraced without ever completing the pattern. In 2008, freshly introduced to the theory, I read that Robert Prechter — who introduced most of us to Elliott Wave — expected the Dow Jones to fall toward 500 while it traded in the 7,000–8,000 range. I am grateful to him for teaching us this beautiful theory, but with respect, the market went on to more than double from its 2009 lows. Of course, the theory keeps provisions — the irregular B, the expanded flat — that justify such moves after they happen. As I said: the theory is always right, irrespective of where the market goes.
The Danger of Bias
Holding a bias toward one wave count is the most fatal thing you can do while trading with Elliott Wave, especially on reversal trades — if the market shoots the other way, you can miss the entire next move. Stay flexible and lean on other tools to gauge direction. Remember, too, that a five-wave move can later be recounted as a three-wave move. The crux of the theory is deciding whether a move is a five-wave impulse or a three-wave correction — yet the very same move, once marked as an impulse, can be re-marked as a correction just to make a count work. Bias makes you count whatever confirms your view.
So Should You Use It?
Despite its drawbacks, Elliott Wave remains one of the best techniques for reading market structure and direction. If you intend to trade with it, accept the limitations: find your setups in combination with tools like RSI and Fibonacci. If you are purely in it for research and enjoy putting wave counts on charts, play away. But if you want to make money with the theory, know this — you cannot use it alone.
