What Is the Sharpe Ratio? How Can You Measure Whether a Trading Strategy’s Returns Are Worth the Risk?

In cryptocurrency trading, a high return does not necessarily mean a strategy is good. If a strategy can generate high returns but comes with sharp volatility and significant drawdowns, we need to ask: are those returns worth the risk? The Sharpe ratio is one tool that can help answer this question.

First, what is the Sharpe ratio?

The Sharpe ratio measures the excess return earned by a portfolio or trading strategy per unit of volatility risk. Generally, the higher the value, the better t

11.13 Friday afternoon Zhongling Gold outlook

Gold 4-hour chart: The range-bound downtrend remains unchanged. Highs continue to move lower. The low at 3852 rebounded to around 3917, a technical correction after a sharp drop, with the weak channel structure intact. 3995 is key resistance overhead. Rebound momentum is insufficient and the recovery lacks strength, leaving bulls with little room to act. Price will most likely repeatedly test the lower low area going forward.

Intraday strategy:
Look to open short positions on a rebound to 3910‑3920, targeting around 3860-3840

Why does trading volume suddenly surge—is the trend strengthening or is the market reversing?

In the crypto market, a sudden increase in trading volume often catches traders’ attention. Some see it as a sign of capital flowing in, while others worry that large investors are heading for the exit.

Why does the price sometimes keep rising when volume surges, while at other times it suddenly reverses?

The key is that trading volume reflects changes in market activity, but by itself, it cannot tell you whether buyers or sellers necessarily have the upper hand.

First, observe how the price behav

Why can prices quickly pull back after the market breaks through key resistance?

In the crypto market, a break above key resistance often attracts traders. But some breakouts last only a short time, and prices then fall rapidly, leaving traders who chased the rally at a disadvantage. This phenomenon is commonly called a false breakout.

First, a breakout does not mean a trend has formed. A brief move above resistance may simply mean buying pressure has temporarily prevailed. If sustained demand does not follow, the price may return to its previous trading range.

Second, stop-loss orders may

The Most Expensive Lesson of the Week: The Market Didn’t Teach Me How to Make Money, but How to Keep My Hands in Check!

This week’s market action was more exciting than a TV drama.
When prices rose, I thought I was an investment genius; when they fell, I questioned my life; when they bounced back, I felt financial freedom was just around the corner.
If I had to pick the trade most worth reviewing this week, it wouldn’t be the one that made the most money, but the one I rushed into out of fear of missing out, even though it didn’t meet my trading criteria.
And the result? The market never show

What exactly is the risk-reward ratio in trading? Why doesn’t a high win rate necessarily mean you’ll end up profitable?

In the crypto market, some traders focus heavily on their win rate, believing that as long as most of their trades are profitable, they will definitely make money over the long term. In reality, win rate is only one part of evaluating a strategy; the size of each profit and loss matters just as much.

First, understand the risk-reward ratio. The risk-reward ratio measures the relationship between a trade’s potential loss and expected profit. For example, if you plan to lose

How can you tell whether a trading strategy has stopped working, rather than mistaking a normal drawdown for a problem with the strategy?

A trading strategy experiencing losses during its operation does not necessarily mean it has stopped working. Any strategy involving uncertainty may go through drawdowns. What really matters is distinguishing normal fluctuations from signs that the strategy's edge is fading.

First, see whether the drawdown exceeds its historical range. If the current drawdown is significantly greater than what was common in historical tests, further investigation is warran

What Is the Funding Rate? Why Can Perpetual Contracts Continue to Incur Holding Costs Even When Prices Barely Move?

In cryptocurrency trading, many people focus only on price movements after opening a position and overlook the funding rate. For perpetual contract traders, even if prices move sideways for a long time, holding a position may still incur additional costs or generate returns as long as the funding rate is nonzero.

First, what is the funding rate?

The funding rate is a mechanism in perpetual contracts for periodic payments between longs and shorts, designed to keep contract pric

Why does a larger account loss require a higher return to break even?

There is a mathematical principle in trading that is easy to overlook: the percentage loss and the return needed to break even are not equivalent. The deeper the account loss, the harder it is to recover to the original capital level.

First, losses and breaking even are not symmetrical. Suppose an account has 100k USDT. After a 30% loss, only 70k USDT remains. To get back to 100k, it needs to rise by about 42.9%, not just earn back 30%.

Second, the deeper the loss, the greater the recovery pressure. After a 50% loss, the

Why doesn’t price necessarily fall immediately when MACD shows bearish divergence?

In the crypto market, when prices keep making new highs while the peaks of the MACD indicator gradually decline, bearish divergence may form. Many traders view it as a short signal, but bearish divergence reflects a possible weakening in upward momentum; it does not mean that prices will necessarily fall immediately.

First, understand what bearish divergence means.

Bearish divergence typically appears when price peaks keep rising while the corresponding MACD peaks gradually decline. This may indicate that upw

Why can trading strategies that perform well in backtests fail in live markets?

A trading strategy may deliver strong returns and a high win rate in historical backtests, while keeping its maximum drawdown under control, yet produce very different results once deployed in the market. The problem may not necessarily lie in the strategy itself; it may also stem from the gap between backtesting and live trading.

First, historical data does not represent the future. Backtesting can only evaluate a strategy’s performance under specific historical market conditions. Market structure, volatility, a
