MACD Seasons: Reading the Market as Weather
One of the things that happens over time, when you're a tinkerer like me, is that you start monkeying around and adding more things to your charts. More indicators, more lines, more conditions. And it becomes hard to teach and hard to see, and the cost of decision making gets extreme. So I went looking for a simplifying lens. I live in Kansas, near cornfields, and the answer turned out to be sitting right outside my window.
MACD Seasons is my market regime framework: four states, Spring, Summer, Fall, and Winter, read directly off a regression-line MACD, each with its own posture toward risk. A farmer does not argue with February. He does not plant corn in the snow because he has a good feeling about it. He reads the season and does the work that belongs to that season. That is the whole idea. You look at one indicator, you name the season, and you know which page of the playbook you are on.
Key Takeaways
- The MACD Seasons framework maps the market into four regimes: Winter (falling, below zero), Spring (recovering, still below zero), Summer (rising, above zero), and Fall (rolling over from the peak).
- Each season changes your setup selection, your sizing, and your expectations. The season itself is never an entry signal; every trade still needs a mechanical trigger.
- You do not predict the season. You recognize the one you are in and act accordingly. It stays winter until it isn't.
Where the seasons come from
The engine underneath is a MACD, with one change. Instead of the standard exponential moving averages, I build it from the same regression lines I already use to frame price in detail, the 10 and the 30. The difference between those two lines, plotted against a zero line, becomes the indicator. Regression lines smooth out the large ocean waves, so you can really see the next higher-order trend instead of every ripple.
Then you draw the zero line and something useful shows up. Every time that MACD crosses below zero, look up at price. Something significant just happened, and it is not good. Price is breaking down. Every time it crosses above zero, the opposite. Those crossings, plus the slope of the indicator between them, give you exactly four conditions. We started thinking about them in terms of agriculture, and the names stuck.
The four seasons
| Season | MACD read | What it means | The work of the season |
|---|---|---|---|
| Winter | Below zero and sinking | Downtrend in force. Bad, getting worse, no hope in sight. | Defense. Small size or flat. Watch for the failing to stop. |
| Spring | Below zero, slope turning up | The decline has stopped failing. Momentum is emerging. | Plant seeds carefully. Starter positions with mechanical entries. |
| Summer | Above zero and rising | Established uptrend. Easy and obvious what's working. | Manage the crops. Hold winners, trail stops, consider adding. |
| Fall | Above zero, rolling over | Momentum weakening at the peak, right when everybody's happy. | Harvest. Take profits, tighten stops, put something away for winter. |
Winter is the MACD below the zero line and sinking. Price is failing, the regression lines are pointed down, and my read is blunt: it's bad, it's getting worse, there's no hope in sight, and it is going to continue to be winter until it isn't. That last clause is the important one. Winter carries no timestamp. A harsh winter, where price is falling so fast it leaves its moving averages and Bollinger bands far behind, tells you the thing is indisputably in play to the downside. You do not stand in front of that. You wait.
Spring begins when the market stops failing. The regression lines flatten out a little. The slope of the MACD turns up while the indicator is still below zero, climbing toward the line. Now I'm interested in spring planting, and especially when that recovery comes out of a deep washout, because a decline that violent leaves the strongest survivors easy to spot. But you plant carefully, because sometimes old man winter comes back. A late frost kills seedlings. So spring positions are starter positions: smaller size, tight risk, and a real mechanical trigger such as a Supported Spring Crossing before any capital goes in.
Summer is the MACD above zero and rising. Everything is growing, it feels easy, and it is easy. The positions you planted in spring are going to be your best winners, and summer is when you manage the crops rather than hunt for new ground. You might take a second position in the names that are working. The discipline of summer is patience: staying in the trade is the work, and the Monkey Brain that wants to grab the first profit is the main threat to the harvest.
Fall arrives at the peak, when everybody's happy and the indicator starts rolling over. That rollover automatically, visually, triggers you to start thinking about harvest and about putting something away for the winter. Take partial profits. Tighten the trailing stops. Nothing dramatic has to happen in price yet; fall is the season where the cost of complacency starts compounding.
One pattern deserves its own mention: summer, fall, summer. In a grinding bull market the MACD rolls over, dips, then turns back up without ever going below zero. That second summer is real information. The move had a chance to fail and it did not. That is a signal you can plant another crop, adding to positions with the trend's endorsement behind you.
What changes with the season
The season does not tell you what to trade. It tells you how to carry yourself. Three things shift.
Setup selection. Some battle drills belong to specific seasons. My favorite reversal entries, the W-shaped bottoms and the Collapsing Dragon, are always preceded by a harsh winter: something said this thing was decisively in play to the downside, and then it reversed at a precise point. Breakout and continuation trades belong to summer. Fading strength belongs to fall, if you fade at all. Trying to run a summer playbook in winter is how accounts get hurt.
Sizing and allocation. When the market goes from spring to summer, maybe you can afford to be a little more growth-oriented. When the market drops into winter, be very careful about the speculative names; maybe don't go all in on those. If you put the seasons on the index itself, that market seasonality starts informing all the correlated and subordinate trades underneath it. It becomes an allocation lens across competing systems, without adding a single new indicator to your screen.
Expectations. Your win rate and your average winner are different in each season, and if you do not track results by season you will misread your own skill. The framework also supports honest forward-looking questions: if the market is in this condition today, where has it been 5, 10, 20 days later, historically? That is a statement about a distribution of past outcomes, never a promise about the next one.
Recognize, don't predict
Here is the discipline point, and it is the one that saves people. You do not predict the season. You recognize it. Nobody knows when winter ends. What you can know, every single day, is which season you are in right now, and that is enough to pick the right work.
And a season is a bias, never an entry. When the MACD moves into spring, that region gives me a bias and an urgency to be buying. It is not a signal to enter. The trade still has to be framed according to specific rules: a mechanical entry, a defined stop, a plan for the exit. Season tells you which trades to look for and how much to carry. Price action tells you when to act. Keep those two jobs separate and the framework stays honest.
The seasons are also fractal. I read them on the daily, the 3-day, the 9-day, and the monthly to build the strategic picture, and I read them on a 30-minute chart intraday. A harsh winter on the 30-minute, followed by a pinch and a reversal drill I have practiced hundreds of times, is one of my oldest reliables. Same seasons, faster calendar.
Start simple. Put the MACD on your main index chart tonight and name the season out loud. Do it every day for a month. You will be surprised how much of your trading confusion was really just seasonal confusion: doing August work in February and wondering why nothing grows.
Frequently asked questions
What are the MACD Seasons in Dr. Ken Long's framework?
Four market regime states read from a regression-line MACD. Winter is the indicator below the zero line and sinking, a downtrend in force. Spring is below zero with the slope turning up, emerging bullish momentum. Summer is above zero and rising, an established uptrend. Fall is above zero and rolling over, momentum weakening at the peak. Each season carries its own setups, its own sizing, its own expectations.
How do you tell which season the market is in?
Two questions answer it: is the MACD above or below the zero line, and is its slope rising or falling? Below and falling is winter. Below and rising is spring. Above and rising is summer. Above and falling is fall. Dr. Long builds the indicator from 10- and 30-period regression lines rather than the standard exponential moving averages, which smooths the noise and makes the season visible at a glance.
Is a season change a buy or sell signal?
No. A season is a bias, never an entry. Spring gives you a reason and an urgency to look for long trades, and winter tells you to defend, but every position still requires a mechanical trigger, a predefined stop, and an exit plan under your own written rules. The season selects the playbook page; price action pulls the trigger.
Do MACD Seasons work on intraday charts?
The framework is fractal. Dr. Long reads the seasons on daily, 3-day, 9-day, and monthly charts for the strategic picture, and on 30-minute charts intraday, where a harsh winter followed by a practiced reversal drill is one of his oldest setups. The definitions do not change across timeframes; only the calendar speeds up.
Risk acknowledgment
Trading involves substantial risk of loss and is not suitable for every investor. The MACD Seasons framework is an educational lens for describing market conditions; it is a classification tool, never a forecast. Seasonal reads lag price by construction and transitions can whipsaw. Past performance does not guarantee future results. Validate every rule against your own data and your own behavior under live conditions before risking capital.
