Simple 'Minor Bottom' again

[rochish]

platykurtic,

Thank you so much for the table. All the column headings are not really apparent, so if you could list them separately, that would be very helpful.

Also, I agree with you that the bottom detector should be viewed on a continuum, rather than in discrete/binary terms (e.g., major bottom or minor bottom). From that perspective, the current signal seems to be a very weak “major bottom” or a strong “minor bottom.”

Many thanks again!

I have been looking for historical data for the WSJ new highs nd lows but have not been able to find historical data. Could you advise where I should look (pay?)

Thanks

Hi aussi,

That’s a somewhat complicated question as the WSJ advance / decline historical data is not available on the WSJ web-site as far as I can determine. There are a couple of alternative options depending on what’s required …

1. If one just wants to obtain the data required for the Simple Bottom Detector then just drop me a note and I can supply it in s/sheet form back to 2005ish.
2. More comprehensive data is available from 2005ish to 10 February 2020 at Advance Decline data. This is where I obtained the original (NYSE advance / decline) data-set and have kept it up-to-date since then.
3. The recommendation when unicorn stopped updating its data set was to transition to Pinnacle Data at https://pinnacledata2.com/. It costs - I’m not sure about current pricing but it wasn’t too expensive last I looked and you’d need to validate it against the WSJ market data - but (from memory) it also extends back further and frankly the Simple Bottom Detector is so simple that it’s probably plug-and-play as the slight-to-moderate differences between data sets isn’t likely at all material. So Pinnacle was where I was planning to look if I needed a greater or longer data set.

I hope this helps!

The Pinnacle Data matches the WSJ data. I’ve purchased it a couple times.

Hi platykurtic

Thanks for the detailed response, very helpful. I looked at the Pinnacle Data and I think I will go down that path. The data goes back to 1965 for NYSE.

Thanks

@aussi - If you look at the old boards, I think you can get my name. You can then search and find an email for me (I’m a mathematician in Georgia). Feel free to email me. I’ve written code that may help you process the data. I’d be happy to share.

historical data for the WSJ new highs nd lows

Try Barchart.com. A free account brings a lot of downloadable data including daily “NYSE” advances, declines and unchanged statistics. They have their own composite indices such as $ADVT, $DECT, $UNCT as well.

The Barchart data does not match the WSJ data in total number of companies, new highs and new lows. My guess is that this is probably not an issue, I am just trying to tag along with platykurtic’s work.

Does the bottom detector look at intra-day lows? I’m wondering because today was an unusual day in the market. The daily range between low and high was almost 200 points on the S&P. The day began with what looked like a bloodbath and reversed into a powerful rally, closing up 2.6% for the day.

Makes me wonder how many traders are watching for bottom signals. Is it possible that a lot of people saw a bottom signal early in the day, which triggered the huge market reversal and the strong close? How many people out there are front running us? If that’s the case, will the signal stop working?

This is what I just heard from Monaco (Jim):

Despite today’s remarkable drop at the open, neither my “short term bottom detector” nor “major bottom detector” models has give even a weak version of a bottom signal since close Sept 29.
(the usual rule being to wait for a “no signal day” before investing, meaning the buy signal was end of day Sept 30)
That doesn’t mean they are right, of course. But they are silent for now.

Here’s what seems to be the main reason the Market was so strong yesterday. Let’s see what today brings.

Stocks ROAR Back!

Nailed it!! Here’s a link that confirms your explanation. Thanks!! It was a massive rally, and one that came out of nowhere. And it’s left market observers like yours truly wondering what the heck just happened. There wasn’t any new data, no headline-making speeches, no event that occurred just after the open to spur such a move. It literally came out of nowhere—and left us grasping for possible reasons. “Today’s market reversal was a head-scratcher,” writes Oanda’s Edward Moya. And he’s n…

The platykurtic bottom detector uses new highs, new lows intra-day data. For Oct 13, from WSJ, NYSE, there were 934 new lows and 29 new highs. Total traded was 3402. I think platykurtic’s approximately one third new lows for major bottom uses total listed, not total traded.

Here’s 2020 - there are no column labels but it should be self evident what the data represents (for some reason it interprets the label line from the s/sheet different to the rest of the table):

Humph. Here’s a great example of how this new format sucks. On the old boards, when I decided that I didn’t want/need to read the entirety of a long post all I had to do was click “next” to skip over the rest of the post.

Now, I can’t. Have to scroooooooollllll down and down and down to get to the next one.

So it turns out there’s a ‘Details’ tag underneath the ‘gear’ icon in the edit box. It allows ‘spoiler’-like collapse-able sections. And so I edited the long table based post to include these tags (see above).

I propose that we attempt to use that details tag moving forward for large data drops. I suspect there’s a few of these types of features that we’re going to need to learn to use the new system at our previous level.

Total traded was 3402. I think platykurtic’s approximately one third new lows for major bottom uses total listed, not total traded.

Just a minor correction - in the simple bottom detector calculations ‘total traded’ or ‘issues traded’ is used.

This is for two reasons…

1. The data is readily available on the WSJ Markets page itself & I’m quite lazy (the main reason).
2. Whether a stock trades or not offers up information on that stock’s status. If in a heavy down move an issue doesn’t trade it’s not contributing to the fall, isn’t likely invest-able & isn’t likely that important.
