Chinese Long-form | Why Does an Effective Trading Strategy Suddenly Stop Working?

Many traders encounter this problem:

A strategy delivers consistent profits and has a beautiful backtest curve, but a few months later, the same parameters and signals start producing frequent losses in live trading.

Is the problem really with the strategy itself?

Not necessarily. A strategy’s effectiveness often depends on the market environment it operates in, not on how much profit it has generated in the past.

There are at least four market conditions worth watching:

1. Trend structure changes

#Gate股票畅聊季 #SNDK #WCTCS9 Sandisk (SNDK) has plunged sharply, falling about 22% in a single day on November 5, but rebounded in after-hours trading on the 6th. There is no sign of a trend reversal yet; this looks more like volatility following a sharp sell-off.

Recent price action
Pullback from the high: The recent high was around $2,354. On November 5, the price briefly fell to around $800 intraday, a decline of about 65%[1].
Weekly decline: From October 29 to November 5, the stock lost about a third over five trading days.
November 6: It closed regular trading at $806.43, down 22.26%; after

Turning 1,200 U into 50k U in 90 days. Everything he did was “the opposite.”
While others chased trends, he stuck to one coin.
While others made ten trades a day, he made one every three days.
While others added to their positions after making money, he withdrew his profits.
After 90 days, his account held 50k U.
It wasn’t that he was smarter than you. He was just more “boring.”
First: He only traded major coins and never switched.
For 90 days, he traded only ETH.
Altcoins up tenfold? Didn’t look.

When everyone is using similar trading strategies, where do the profits come from?

A question worth considering:

If a trading strategy really works, why can't it work forever?

Suppose a simple breakout strategy was able to capture trends in past markets. As more and more traders discover this pattern, they begin buying at similar price levels and placing stop-losses at similar levels.

The initial edge may change.

This involves an important concept: trading edges are affected by the behavior of market participants.

1. What happens when an edge is widely used?

First, trading activity may

By the way, nothing I've shared today is coming from Sahil or anyone on his team. My portfolio allocation is my choice and my responsibility.
Looking back, shocked I even replied. He's been blocked for months and his current crash out is something I'm watching and also taking with a grain of salt.

The Fed decides on rates again on October 28. Since the start of the year, WTI crude is up about 73%, and household inflation expectations have risen by half a percentage point. Core inflation sits where it started the year, but September's CPI, covered here last week, came in above forecasts on both the annual headline and core rates.

Yields have climbed too. The two-year Treasury yield, which tracks where traders expect policy rates to go, has risen by more than full percentage point this year, to 4.8%. It now sits well above the 4% top of the Fed's target range, even after the hike on Sep

The market was highly volatile this week, with constant long wicks, making it easy to get stopped out repeatedly.
BTC and ETH bulls and bears took turns battling it out. We stuck to the plan, accepted small pullbacks, caught the main move, and locked in steady overall gains.

A One-Year Plan for a Small Account (Follow It, Don’t Skip Steps)
Don’t set profit targets; set behavioral goals. You can’t control profits, but you can control your behavior.
Months 1–2: Just keep records; no profit targets
At most 3 trades per week, with 1% risk per trade
Write three lines for each trade: why you entered, where your stop-loss is, and why you exited
At the end of the month, don’t look at your P&L. Just ask: Did I follow the plan?
The only goal at this stage: build the habit of keeping records.

Months 3–4: Trade just one asset and one setup
Choose ETH or BTC; don’t add anythi

Why might a trading strategy that performs well in historical backtests gradually stop working in live markets?

A beautiful return curve does not necessarily mean a reliable trading strategy.

In the cryptocurrency market, many traders use historical data to test entry signals, take-profit and stop-loss levels, and position sizing parameters. But once a strategy is deployed in the market, its win rate may fall, drawdowns may grow, or it may even lose money over the long term.

What exactly is going wrong?

I. Historical data is not the future market

Backtesting only shows how a strategy perf

4 little-known facts that will make your heart ache once you do the math
① Annualized funding rates are scarier than you think
0.01% / 8 hours × 3 times/day × 365 days = 10.95% / year
It may look like just one ten-thousandth each time, but over a year that's 11% of your principal.
In a high-funding-rate market (0.1%/8h), the annualized rate is 109%.
So even if you're right about the direction, funding fees can eat up all your profits if you hold long term.
Before placing a trend trade, check the current funding rate.
② There are two types of stop-loss orders, and they work very differently
Mar

Here are 4 more little-known facts. This round: “How emotions are quantified” ① Funding rates have a cap, but when they hit the limit, they can get brutal. The single-period funding rate cap for most tokens is around 0.75% (with slight variations across tokens). You barely notice 0.01% in normal conditions, but in extreme markets, rates can hit the cap for several periods in a row. Hitting the cap means longs (or shorts) are being squeezed hard, and the market has become heavily one-sided. If rates keep hitting the cap, it doesn’t mean the trend is strong—it could reverse at any moment. ② The

🔐 Beyond Solvency: Why Storage Architecture Dictates the Future of Exchange Security
The centralized digital asset trading landscape is undergoing a massive structural transformation. For years, the gold standard of platform transparency was limited to Proof of Reserves (PoR)—a snapshot method verifying that an exchange holds sufficient tokens to back user balances on a 1:1 ratio. However, recent market vulnerabilities have proved that simply possessing assets is only one part of the security equation. True safety depends on how those assets are stored, who controls the und

① Get-rich-quick narratives
What you see in your feed is always “turn 5,000 into 5 million.” Nobody posts “30% annualized returns over three years.”
Because the former ignites your instincts, while the latter gets no traffic.
