USING THE FISHER TRANSFORM By John Ehlers . Using The Fisher Transform.pdf

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.

Finally... a good description of what you want ! now re-write that in the following manner: -- write out one thought at a time, -- write out ONE action at a time, -- break down complex actions into multiple small actions, -- write out one action per sentence, -- write out one sentence per line... you should have your indicator in pseudo code by the end of this exercise !

Isn't this what your code (post#3) is doing ? Can you explain the difference?

Since nobody pressed the "Report" key... I guess it is not as "negative" as it looks. My suggestion is -- Carry On !

You should post a picture of your torso every week... This might turn out to be a more popular thread than your P/L journal. ;-)>

you can always press the "Report" key. That's what it is for.

YES... that is it... computers are DUMB... lowercase is lowercase, and UPPERCASE is UPPERCASE. THEY ARE NOT THE SAME... LOL

my mistake... that's the name of the function. ok I think I have an idea of what is the problem... let me think it through a bit more first....

of course that is the way it is supposed to be... either numeric OR string, but NOT both.

try this and see what you get in the output window: print( SymbolText + " " + NumtoStr(BarInterval,0) + " minute just fired off" );

This is a mutual relationship. You can start by sharing your Amibroker indicators... and this would encourage others to do the same. note: when I say "sharing", I don't mean copying indicators from the Amibroker site.

(edit) I don't see you declare symboltext in the var: .

no need to export it from MultiCharts... eSignal ;-)>

You don't need TradeStation to make a mock up. Just use the Window's built-in Paint program; You can whip up something quite quickly.

Yes -- Buy MultiCharts. (with tongue-in-cheek)

if cost is an issue... then NinjaTrader is the obvious starting point. Ninja is free, until you trade live. Mind you, Amibroker PRO costs only $279 one time fee -- hardly a stumbling block for any aspiring trader. Ninja supports C#... it might be preferred over Amibroker's proprietary AFL. I should point out that Amibroker's AFL is a subset of C. i.e. you should have no problem adapting to either. Some people consider Amibroker's graphics more inuitive, others like Ninja's comprehensive training. I have tried both programs, I found both are capable software.

No codes needed... That's part of the View>Strategy Performance Report.

This is grade 12 mathematics. No, it does not have to be complicated. and NO, I do not know what you are trying to do here. I cannot read your mind. That's why it is important to post a mock up.

You have to "close" the Manage Attachments window after uploading. Otherwise the attachment will not take hold.

I have posted 2 comparative charts at the bottom of this thread: http://www.traderslaboratory.com/forums/f46/quick-ma-4504.html

Fourier Transform by John F. Ehlers Have fun with colors... This is as much an exercise in programming as a psychoanalytical experience. Feel free to share your signaling enlightenments. Fourier_Transform_(MultiCharts).pla Fourier_Transform.txt

how would you like to define the slope? how do you perceive the color change? can you post a mock up?
