How to Make a Data into an Oscillator?

Recommended Posts

Hi, this is one of my first posts here but I've been lurking for a while. I'm a professional software develop (Java) and I've been developing trading systems and tools, both automated and discretionary. However I'm not that good at math.

 

I have some data that I'd like to turn into an oscillator but I'm not sure how. Ideally I'd like my oscillator to go between 0 and 100 if possible but that's not totally necessary. I've been playing around with the stochastic formula and also MACD. It seems those are the most used to make oscillators.

 

To take a couple examples, I'd like to make an oscillator of the put/call ratio. One could say it's already an oscillator but it's not centered around zero and it often leans one way or the other for long periods of time.

 

Another example is the TICK index. I'd like to come up with an oscillator for that.

 

Another example is I'd like to see if I can use the overnight range (using ES for this example) to make something useful. I have no idea if this will work but I'd like to give it a shot.

 

I can handle the coding, so if you feel like sharing some ideas I'll code it up and post the code & charts for everyone's benefits. I'm hoping we can come up with something useful together.

You might want to look at John Ehlers work. he approaches things from a signal processing point of view which is quite appropriate for oscillators. A variety of his ideas have been coded in a variety of languages. Often he starts by trying to isolate the cyclical component from any trending component.

 

Cynthia Kase has some interesting ideas like the Kase Peak Oscillator.

Hi, thanks for your reply. It's a coincidence that you mention these two because I have recently been looking at both of them.

 

I am currently playing with Ehler's sine wave but I thought it only applied to price. Could it apply to other data too?

 

I have also demo'd the kase oscillator. It's great for detecting divergences but I couldn't get her method (from her book) to be profitable, nor could I get her kase easy entry system to be profitable. I concluded that it's good for detecting divergence which can be warning signs but often I found a strong trend and I'd get out because of the divergence only to watch it continue on for a while. Price often does pullback after a divergence but often it resumes. So I wasn't able to find a way to incorporate it into my trading.

 

Also on the kase peak, can it be applied to non-price data? I didn't try this.

 

In summary, I'm looking for a way to take data and make my own oscillator. For example the trin goes from say near 0 to 2. I'd like to make it 0 to 100 and have it centered at zero. Same for pc ratio, a/d line, etc.

If you want an "indicator" that can only vary within a certain range (e.g. 0-100) you can always use the stochastic formula as a basis.

As input you would use e.g. the put/call ratio or the tick value (instead of price, as usually done).

 

 

But: Please think if it is wise to do so.

 

In my view it is important to get as much information as you can from the data you have access to.

If you notice that P/C ratio is "leaning" then this is valuable information which should not be eliminated by a formula that forces values into an artificial range. For me it is clearly the task to get as much (valuable) information as possible not to cut it down.

fit a moving average on the basis...

then the data can oscillate around it.

This wasn't the answer I was looking for but after playing around with various combinations of stochastics and bollinger bands, I have to agree with you that the pc ratio data has more information in it than the oscillators I made. The only problem is I wanted to do some backtests to test out some ideas and for that oscillators are useful.

I had a few things done and tradestation crashed and the stupid thing lost everything I've done since my last backup which was Friday. (What a POS!!!). At least Ninjatrader kept the source code in ascii files on the PC so they could never get corrupted. Anyway, the stuff I made was simple so I'll redo it and if there is interest I'll post what I come up with...

The markets continue to assess the election results as President-elect Trump fills in his cabinet choices, with the key Treasury Secretary spot still open. The Fed’s rate path continues to be debated with a -25 bp December cut seen as 50-50. Earnings season is coming to an end after mixed reports, though AI remains a major driver.

Asian stocks rose after  Nvidia’s rally. Nikkei added 1% to 38,415.32 after the Tokyo inflation data slowed to 2.3% in October from 2.5% in the prior month, reaching its lowest level since January. The rally was also supported by chip-related stocks tracked Nvidia. Overnight-indexed swaps indicate that it’s certain the Reserve Bank of New Zealand will cut its policy rate by 50 basis points on Nov. 27, with a 22% chance of a 75 basis points reduction. European stocks futures climbed even though German Q3 GDP growth revised down to 0.1% q/q from the 0.2% q/q reported initially. Cryptocurrency market has gained approximately $1 trillion since Trump’s victory in the Nov. 5 election. Recent announcement for the SEC boosted cryptos. Chair Gary Gensler will step down on January 20, the day Trump is set to be inaugurated. Gensler has pushed for more protections for crypto investors. MicroStrategy Inc.’s plans to accelerate purchases of the token, and the debut of options on US Bitcoin ETFs also support this rally. Trump’s transition team has begun discussions on the possibility of creating a new White House position focused on digital asset policy.     Financial Markets Performance: The US Dollar recovered overnight and closed at 107.00. Bitcoin currently at 99,300,  flirting with a run toward the 100,000 level. The EURUSD drifts below 1.05, the GBPUSD dips to June’s bottom at 1.2570, while USDJPY rebounded to 154.94.
