Has anyone created Bill Williams Moving Averages which are used for the Alligator? If so would you be willing to share them? I used Metastock for almost 20 years and was fairly good at programming but I recently switched to Ninja and their programming making my eyes spin. Cheers.
Can you help answer these questions from other members on NexusFi?
Sorry to add but didn't want to start a new thread, anyone know of a williams pro go indicator or similar for Ninja
used to use it in quotetracker and was very useful imo
Bar charts definition: This indicator has two lines: the Public Buying (green line) at the beginning of the day and the Professional Buying (red line) at the end of the day.
This technique is to create two Advance/Decline lines.
The Public Advance/Decline line is constructed by using the change from yesterday's closes to today's open.
The professional Advance/decline line is constructed by using the change from today's open to today's close.
The lines are calculated by taking a moving average, normally 14-days, of the results
thanks I didn't see anything here or ninja forum, thought maybe something similar around

The indicator will only give different results from a momentum indicator, if there are significant gaps between the prior bar's close and the current bar's open. It can only be used
- on daily data
- if your daily bars are built from the RTH session (regular session excluding the night session)
If there are no gaps between bars, the indicator becomes a simple momentum indicator.
I do not understand, why Williams qualifies the night session move as public move and the day session move as professional move. The night session is essentially driven by overseas news. Qualifying this as noise and considering the US session as professional trading reflects an attitude which might have worked 30 years ago. Today that reasoning may only be correct for US domestic stocks, but certainly not for FOREX or commodities that are traded round the clock.
I think you can just use the momentum indicator, and that should be fine.
Thanks for replying, I'm not sure how quotetracker calculated it or if standard across the board , I used to use it in combination with synthetic $vix and had interesting results for showing extremes , see if I can remember and dig some more...
just something I remembered and was quite useful...

these are smoothed moving averages (also called modified or running) in the alligator, not simple - it is a kind of exponential smoothing
I just found out that in ninjatrader (and everywhere else of course) we can build the alligator with ordinary exponential moving averages - just the periods be 25 for jaws, 15 for teeth and 9 for lips - (orig.Number)x2-1, all else the same
Bill Williams did indeed use the SMMA (smoothed moving average), but there are two different formulas used for the SMMA. I called them "useless SMMA" (your EMA) and "simple SMMA" in my thread here:
I had recently stumbled upon the smoothed moving average or SMMA, which is used by many other indicators such as shaded moving averages, the Supertrend and channel indicators. I had then simplified the code , but the indicator left me confused, as I …
Are you sure that you picked the right SMMA? Could you point me to your source please?
As far as I know the other version of the SMMA is mostly used. The other version is near-identical to the SMA.
ummm... actually that exact thread of yours is where I got the idea - and thank you for that - then I checked Bill Willliams' books - his daughter is reffering to the CQG's formula for smoothed moving average on Trading chaos 2nd edition pages 104-105 (I downloaded it from 4shared for free I think) - cqg.com/Technical-Analysis/Studies/Standard-Studies/Moving-Averages.aspx (I can't post full links), wikipedia got an article about: en.wikipedia.org/wiki/Moving_average, which relates that Smoothed MA to the Exponential
then I checked on platforms with alligator integrated that I have if it really is like that - on metatrader 4 and 5 and tradeinterceptor it was a complete match (as of what can be seen on the chart when both indicators are plotted)
I am not that into coding of ninjatrader so it would be the right thing to do to check once again if the formulas really match
what really matters is why do we need a Smoothed MA
if we want to calculate one more kind of MA - then that formula is indeed useless - it isn't really anything new or better
but if we need it to build the alligator on platforms that don't have it or that smoothed MAs - it saves a lot of time to know this (that was the reason I wrote that comment yesterday) and I thank you once again for pointing it out
I think even if there happens to be some actual difference between the actual values of that two formulas it shouldn't be harmfull since the alligator itself is a simplified "close-enough" representation of much more complicated calculations
Yes there are two SMMAs. As you pointed out, one of them is an exponential moving average, and the other one comes pretty close to the default SMA. Easiest to build an alligator that can perform calculations based on either a SMA or EMA. It is more the idea that counts.
