Day Eighty-Nine · Open Interest Is Quietly Growing
When the river surface freezes, you can’t see the water flowing.
But beneath the ice, fish are swimming, aquatic plants are growing, and pebbles are being worn rounder by the water flow. You stand on the shore, and you can see nothing. Only the occasional crack of ice—snap—like the river has turned over.
Open the Open Interest indicator; that line is also beneath the ice.
Price moves sideways—can’t rise, can’t fall. The candlesticks look frozen, making people drowsy. But when you check the Open Interest, it’s quietly growing. Not for a

Eighty-eighth day · The Bollinger Bands Finally Opened
Waiting for eighty-eight days.
The upper and lower bands of the Bollinger Bands, like two tightly closed lips, are getting narrower and narrower. The candlesticks are squeezed in the middle, gasping for air. The group is quiet, comments decrease, and the number of followers drops a few. Someone asked me: What are you still persisting?
I said: Waiting for it to open.
This morning, I opened the chart. The upper band starts to lift, the lower band begins to dip. That corridor, narrow to the point of being as thin as it can be, finally

The 87th Day · OBV Doesn't Lie
Shout into the valley, it takes several seconds for the echo to return.
It's not that the valley is lazy, but that sound travels too slowly. You shout out, it hits the opposite mountain wall, bounces back, hits again, and bounces. By the time it returns to your ears, you might have already forgotten what you shouted.
Open the OBV (On-Balance Volume indicator), that line is also slowly moving.
Prices can jump up and down, restless like monkeys. But OBV doesn't go crazy with them. When funds flow in, it quietly climbs upward; when funds flow out, it slowly

Day 86: The underlying understanding of trends and oscillations is all about inertia; similar patterns repeat, and only inertia allows for continuation, ensuring a high win rate. Without a regular pattern, the operational space is greatly reduced.
Suddenly remembered an old indicator—called "Market Sentiment Ratio." It’s not calculated with a formula; it’s listened to with your ears. When it’s noisy, be cautious; when it’s quiet, pay attention.
As long as you confirm the trend, taking two losses doesn’t matter; trying a few more times will definitely yield results. Taking losses is better

Eighty-fifth day · For those who understand, one is enough
Sitting on the balcony last night, counting the lights across the building.
The lit windows, one, two, three... the whole building probably has over forty households, with fewer than ten lights on. But you don’t feel lonely. Because behind those lit windows, some are cooking, some are watching TV, some are cuddling their children to sleep. Behind each light, there is a complete world.
#Today I opened the backend and saw the names of those who have been liking and commenting all along—not many, just a few.
But I suddenly feel th

Day 84 · You're still here, and that's the best indicator
Over eighty days ago, I started writing here.
Writing about candlesticks, Bollinger Bands, Fibonacci, support and resistance. Also writing about mint on the windowsill, clouds after rain, seeds that stay silent in the soil. Some come, some go.
This morning, I received a private message. The person said: "I've been following you for over eighty days. When you were floating losses, I was also floating losses. You didn't cut, I didn't cut. Today, my account turned green again, thank you."
I was stunned for a moment. Turns out, you

Day Eighty-Three · Support and resistance are the two banks of the river
The river water will not overflow the banks.
When it rises, it approaches the left bank; when it falls, it approaches the right bank. But most of the time, it flows quietly in the middle. The banks are its boundaries and also its protection.
Open the chart, and support and resistance are those two banks.
When the price drops to support, like the river water approaching the left bank. Some start buying, some start fearing, and the riverbed supports it.
When the price rises to resistance, like the river rushing to

The Eighth Day · The Maximum Drawdown is the Bend of the Stream
A mountain creek is rarely straight.
It winds around rocks, turns under tree roots, makes a loop in a low spot, then slowly flows out. From start to finish, it takes a much longer path than a straight line. But it’s precisely those bends that help it avoid obstacles, gather strength, and eventually merge into the river.
The maximum drawdown is the bend in the account’s net value curve.
You move downward from a high point, thinking you’re lost, thinking you can never return. But that’s not true. The market is just avoiding

Eighty Days · The Profit-Loss Ratio is the Balance Scale
In an old Chinese medicine shop, there is a steelyard scale.
The brass weighing tray, the slender scale rod, with tiny star points embedded on it. The person grabbing herbs places the herbs on one side, the weights on the other, lifts, and sets it down—just right, neither too much nor too little.
Trading is the same. Every transaction is a scale.
One side is risk—you’re willing to lose how much; the other side is reward—you hope to earn how much.
Only when the balance is right is it worth making a move.
Not every trade needs

Day 79 · Funding Rate Is the Market's Temperature
In the morning, feeling your forehead tells you whether you have a fever.
The market is the same. The funding rate is its thermometer. When it's hot, the bulls are feverish, everyone is excited, even the most cautious start shouting "This time is different."
When it's negative, the bears shiver, panic spreads, and only sighs remain in the group chat.
But you know, a fever is not a disease; it's the immune system fighting.
A high funding rate is a warning from the market: it's time to cool down.
A low rate is the market saying: we're f
