Thirty-nine years after Wall Street’s infamous Black Monday, the market was still doing what it does best: separating disciplined traders from enthusiastic button-pushers.
BLACK MONDAY — I WAS THERE, KID!
October 19, 1987.
A date permanently tattooed into Wall Street history.
The Dow Jones Industrial Average collapsed 508 points, or 22.6%, in a single trading session.
No circuit breakers. No comforting CNBC talking heads explaining why everything was going to be just fine.
Just pure, unfiltered financial carnage.
And right in the middle of that historical circus was a 27-year-old PTGDavid, working as a market maker for Shearson Lehman Brothers.
Yes, folks, the Silver Fox was there before the silver showed up!
Fast-forward exactly 39 years.
The S&P was trading around the 7700 neighborhood, and the trading room was discussing how a 508-point move today would be a very different animal.
Markets evolve. Technology changes. Human psychology?
Still running the same buggy software installed somewhere around 1792.
Fear. Greed. Hope. Panic.
Different century. Same circus.

THE OVERNIGHT RALLY — MISSION ACCOMPLISHED BEFORE BREAKFAST
Cycle Day 1 arrived with the overnight rally having already satisfied the expected range objective.
That’s right.
The market had completed its initial assignment before many traders had finished arguing with their coffee machines.
By 9:31 AM, PTGDavid had identified the early 32–52 Sandbox Range, providing the initial tactical boundaries.
The morning auction was shaping up as a non-trending, rotational affair.
Not exactly the kind of environment where you strap on a rocket pack and chase every green candle.
But apparently, somebody always volunteers.
10:18 AM — NEW ALIGNMENT LONG
A fresh alignment-long opportunity developed, demonstrating that tactical opportunities could still emerge within a broader rotational environment.
Meanwhile, slatitude39 reported a BLT short at 52.75 for +10 points around 10:30 AM.
Nicely played.
Proof that you don’t need a 100-point trend day to extract opportunity.
You need a setup.
An edge.
And preferably a functioning brain attached to the mouse.
By 10:41 AM, PTGDavid had officially labeled the morning conditions:
NON-TREND RHYTHMS EARLY.
Translation for the overly enthusiastic:
Stop treating every five-point wiggle like the opening scene of a historic bull market.
MARKET PROFILE 101 — THE AUCTION DOESN’T CARE ABOUT YOUR OPINION
Much of the morning discussion centered on Market Profile, Volume Profile, chart alignment, and the proper interpretation of price structure.
Several traders asked questions about the PTG indicators, A4/A10 settings, the 89 EMA filter, and chart overlays.
PTGDavid shared educational materials, including the Sierra Chart Price Study Overlay tutorial and two Market Profile references.
Because apparently, understanding where the market is conducting business is slightly more useful than buying because a candle turned green.
Market Profile isn’t about predicting the future.
It’s about identifying where the auction has found value, where it has rejected value, and where the next meaningful decision may develop.
And today’s session was about to provide a rather beautiful live demonstration.
NOON — THE 7768–7770 DECISION ZONE
There it was.
The critical price neighborhood:
7768–7770
PTGDavid had outlined the conditional roadmap.
Acceptance above? Buyers earned the opportunity to explore higher prices.
Rejection below? Sellers gained the tactical advantage.
Simple.
Elegant.
No need for seventeen oscillators, three economic forecasts, and a motivational speech from your favorite trading influencer.
At 12:01 PM, the auction rendered its verdict.
REJECTION!
The market failed to sustain acceptance at the critical zone.
The edge of the Volume Profile provided the contextual evidence.
Then came the break of the 7763 handle.
And just like that, the BLT short setup came alive.
At 12:03 PM, PTGDavid described the opportunity as a beautiful BLT short play.
Beautiful indeed.
The Bears didn’t need to knock on the door twice.
The Bulls had already misplaced the keys.
THE REAL LESSON
A resistance level by itself is not a short trade.
A support level by itself is not a long trade.
Price behavior at the level is what matters.
The 7768–7770 zone provided the location.
The rejection provided the information.
The break below 7763 provided additional confirmation.
Alignment. Assignment. Attack.
That’s the PTG playbook.
Not:
Guess. Hope. Average down. Pray.

AFTERNOON CHOP — WELCOME TO THE NO-EDGE MOTEL
By 1:31 PM, price had returned to the middle of the opening range.
And what did PTGDavid announce?
NO CLEAR EDGE EITHER DIRECTION. SITTING ON HANDS.
Imagine that.
A professional trader choosing NOT to trade.
Somewhere, a commission broker just shed a tear.
But this was precisely the correct tactical mindset.
The morning had offered defined opportunities.
The midday rejection had delivered a clean technical lesson.
The afternoon?
Well, the afternoon was looking increasingly like two exhausted heavyweight boxers leaning against each other in the twelfth round.
Lots of movement.
Not much progress.
And absolutely no reason to start throwing punches simply because you were bored.
2:56 PM — CYCLE DAY 1 REPAIR MODE
By late afternoon, PTGDavid summarized the session’s developing structure.
The overnight rally had fulfilled the expected Cycle Day 1 range.
The regular session had featured rotational, non-trending behavior.
And the afternoon had settled into consolidation around the middle of the range.
Importantly, the day’s price action had helped repair the previous session’s sell-down damage, with the auction showing signs of stabilization.
This wasn’t necessarily a fresh bullish breakout.
Nor was it a full-scale bearish collapse.
It was an auction repairing damaged structure and searching for equilibrium.
Think of it as the market’s maintenance department showing up after Friday’s demolition crew had gone home.
Somebody had to sweep up the broken glass.

PTG EDUCATIONAL TAKEAWAYS — CLASS IS IN SESSION
1. THE RANGE WAS ALREADY SATISFIED.
When the overnight auction has completed the expected Cycle Day objective, don’t automatically assume the regular session owes you another full expansion.
The market isn’t a charitable organization.
2. LOCATION IS EVERYTHING.
The 7768–7770 decision zone mattered because price behavior there provided actionable information.
Trading random candles in the middle of nowhere?
That’s not strategy.
That’s recreational gambling with better monitors.
3. PROFILE REJECTION MATTERS.
The failure to gain acceptance at the Volume Profile edge provided the context for the bearish setup.
Better read.
Better decisions.
Less explaining to your spouse why the trading account needs another deposit.
4. RECOGNIZE THE RHYTHM.
Non-trending sessions demand a different execution mindset than directional trend days.
Trying to force trend continuation in a rotational market is like trying to teach a goldfish to climb stairs.
Technically ambitious.
Operationally ridiculous.
5. SITTING ON YOUR HANDS IS A POSITION.
When price returned to mid-range and the directional edge disappeared, PTGDavid stood aside.
No edge.
No trade.
No apology.
6. THE PLAN COMES BEFORE THE TRADE.
If price accepts above resistance, prepare for higher exploration.
If price rejects resistance, prepare for downside rotation.
If neither scenario develops?
Do nothing.
Become a scenario-execution machine, not a prediction-addicted button masher.

FINAL BELL — 39 YEARS LATER, THE MARKET STILL HAS A SENSE OF HUMOR
October 19, 1987, was a day when Wall Street discovered that markets could fall a whole lot faster than anyone imagined.
October 19, 2026, was considerably more civilized.
The overnight rally fulfilled the expected Cycle Day 1 objective.
The morning delivered rotational opportunities.
The midday auction rejected the 7768–7770 decision zone and offered a clean BLT short opportunity.
And the afternoon?
Well, the afternoon reminded everyone that sometimes the best trade is the one you have enough discipline NOT to take.
The market had spent the session repairing previous damage, stabilizing its auction, and keeping both Bulls and Bears sufficiently entertained without committing to a fresh directional campaign.
And the Silver Fox?
Thirty-nine years removed from Black Monday, still reading price, still respecting risk, and still reminding traders that surviving the game is considerably more important than winning every hand.
PTG BOTTOM LINE
Respect the Cycle.
Read the Profile.
Trade the Rejection.
Manage the Risk.
And when the market offers nothing but mid-range chop?
SIT ON YOUR HANDS!
Because the market will always provide another opportunity.
Your trading capital, however, does not come with unlimited refills.
Not Dead. Can’t Quit.
