Fisher Transform

by John Ehlers

 

 

The fisher transform indicator by John Ehlers is a range oscillator showing

where today's price is within the past N-days highest and lowest.

It has some smoothing, plus what's known in mathematics as a fisher transform.

 

The range position is similar to Stochastics and to Williams %R.

The fisher transformation stretches out values near the N-day high

and low to make large peaks so as to help highlight those extremes.

 

The calculation is as follows:

The prices used are the midpoint between the day's high and low (as in most of Ehlers' indicators).

Today's price is located within the highest and lowest of those midpoints from the past N days,

scaled to -1 for the low and 1 for the high.

 

     price = (high + low) / 2

                       price - Ndaylow
    raw = 2 * -----------------------     - 1
                   Ndayhigh - Ndaylow

 

This raw position is smoothed by a 5-day EMA (see Exponential Moving Average)

then a log form which is the fisher transform,

before a final further 3-day EMA smoothing.

 

     smoothed = EMA[5] of raw

                                       1 + smoothed
    fisher = EMA[3] of log ------------------
                                       1 - smoothed

 

The effect of the logarithm is to make “smoothed” values near 0 remain near there,

but values near 1 and -1 grow greatly, thus highlighting extremities.

A “smoothed” value of exactly +/-1 would transform to +/-infinity,

so a clamp of 0.999 is applied, effectively limiting the final result to about +/-7.5.

Hi Tams,

 

I have implemented this one some time ago for myself,

you know, in Java for evaluating LR angles.

Java, so it makes not much sense to post it here.

 

I haven't implemented the Fourier one (but have thought about it),

and I am impressed by your implementation (picture).

 

I also like Ehler's work, like others here.

 

But I have a question for you, with all my respect:

 

Which of your indicators are you using to trade?

 

 

Regards,

 

Hal

 

P.S.: I don't use all the indicators I have implemented during time, just a few have survived. And maybe these will die as well sooner or later.

      Date: 22nd January 2025.   Netflix Earnings Surge Driving the NASDAQ to Monthly Highs!   The NASDAQ increases in value for a fourth consecutive day, gaining momentum after Netflix stocks rise more than 15%. Earnings reports are gaining speed for the technology sector, but why has Netflix stocks seen such a high and sudden rise in demand? Netflix Stocks Increase 15% Supporting the NASDAQ! Netflix stocks have been one of the best-performing stocks within the NASDAQ, rising more than 79% in 12 months. However, even for Netflix, a 15% rise in less than 24 hours is considered substantial. The quarterly earnings report was made public by Netflix after the market closed on Tuesday. The earnings report confirmed the following: Netflix beat their earnings per share expectations - $4.27 reported vs $4.21 expectations. Netflix’s revenue surpasses the previous quarter - $10.25 billion this quarter vs $9.82 billion in the previous quarter. The online streaming company confirms projects to expand into live sport and event streaming will proceed. In addition to this, the company’s forward guidance for 2025 remains positive. Netflix is the 10th most influential company for the NASDAQ meaning the positive earnings data and bullish price movement supports the overall price of the NASDAQ. In addition to this, the positive earnings improve the sentiment towards the entire US technology sector. Investors will now turn their attention to the quarterly earnings report for Intuitive Surgical. Intuitive Surgical stocks on Tuesday rose 1.94%. How is the Economy And Politics Affecting the NASDAQ?     The US stock market is witnessing an upward correction after struggling in the last weeks of 2024. The bullish price movement is a result of a sharp decline in bond yields, the new US administration and earnings season. Investors remain relieved that bond yields have fallen back down from the 5.00% level. If bond yields continue to decline further, particularly below 4.50%, the move would be deemed as positive for the US stock market. President Trump took office on Monday and so far the pro-US rhetoric from the President, Vice President and Secretary of State continues to support the stock market. So far, the main concern is how upcoming tariffs can negatively affect inflation and growth. However, some economists advise tariffs will become the “norm” and may have a lesser effect compared to 2018. However, this is something traders will continue to evaluate and monitor. The VIX this morning fell 0.83% lower and trades more than 5.70% lower over a 7-days. The lower VIX indicates a higher risk appetite towards the stock market. If the VIX continues to decline a strong buy indication may materialize. On the most influential stocks for the NASDAQ, 82% rose in value on Tuesday. However, Apple stocks, the most impactful stock, fell 3.19% due to poor sell data. If Apple stocks continue to decline, the NASDAQ’s upward trend may come under strain. In the meantime, investors over the next week will continue to monitor upcoming earnings reports. NASDAQ - Technical Analysis The price of the index is trading significantly higher than all Moving Averages on a 2-hour timeframe and relatively high on oscillators. These factors indicate that buyers are controlling the order book. However, price action also confirms the latest impulse wave measures 3.43% which is normally the point at which the index retraces. This is something that investors may also consider. The retracement potentially also may be triggered by Netflix buyers quickly selling to cash in profit after the sudden 15% bullish surge. If a retracement does indeed form, price action and the 75-period EMA indicates that the pullback may drop as low as $21,391.30.     Key Takeaways: The NASDAQ increases in value for a fourth consecutive day, but price action signals a possible retracement before continuing its bullish trend. Netflix stocks increase more than 15% due to strong earnings data. Netflix beat earnings and revenue expectations by 1.39% and confirmed projects to add live sports streaming to its platforms. The VIX trades more than 5.70% lower over a 7-days and US Bond Yields remain at recent lows. On the most influential stocks for the NASDAQ, 82% rose in value on Tuesday.
