Complex numbers might seem tough, especially when trying to predict how the stock market will move.

Challenges:

• Stock market data is often messy and hard to predict.
• Using complex numbers, like $a + bi$, makes the analysis more complicated.
• There isn’t always a clear connection between how the market behaves and complex math.

Possible Solutions:

• Use Fourier transforms to analyze signals.
• Use complex analysis to find patterns.

Even though complex numbers can be useful in theory, using them in finance comes with many hurdles.
