The Discrete Fourier Transform Indicator was written by John Ehlers and more details can be found at https://www.mesasoftware.com/papers/FourierTransformForTraders.pdf

I have color coded everything as follows: blue line is the dominant cycle, orange line is the power converted to decibels, and I have marked the other line as red if you should sell or green if you should buy

Let me know if you would like to see me write any other scripts!

Good script! But Ehlers said this should only be used in relation to the decibel (i.e DB > 10 to detect a proper signal) across many lookback periods. That's why I think he used a DFT heatmap so he can look at many periods to determine at which period DB>10. Otherwise he said DFT is not reliable.

@daniele.drago.18, thank you! So the blue indicator can be used to get the trend information. When it drops suddenly it means the current trend is either about to slow down or end. The orange line can be used to see the current cycle of the stock
