Does the bear market turn the chart upside down into your bull market?

This idea is too naive; I used to think the same way, which was a display of ignorance.

The bear market is called a bear market not just because of a one-sided decline, but there is also a key point: the funding rate is usually negative.

This means that the short sellers and the bearish sentiment are very high, and the shorts have to pay a higher funding rate. What's more troublesome is that some exchanges can adjust the funding rates, which you may not know.

Moreover, liquidity clearly decreases in a bear market, making it easy for the market to experience significant short-term volatility due to some not-so-big news.

Many exchanges will raise the margin rate for short selling, or even indirectly increase the margin by raising the funding rate.

Human nature dictates that most people are more willing to be bullish rather than bearish; trading is essentially a game of capital against capital, underpinned by human nature.

This also explains why violent rebounds often occur in bear markets.

The risk of short selling is much greater than going long because the maximum loss from short selling is 100% (zero), while theoretically, the profit from going long is unlimited.

Thus, the costs and risks of short selling far exceed those of going long, especially in a bull market, where the risks of short selling are even higher.

In summary:

Both are trend-following operations, but the risks and costs of short selling are always higher than going long.

This is why mature traders rarely short sell; it’s not that they have much confidence in the market, but they understand the risks and costs and know whether they can withstand them.

If you can't make money in a bull market, what makes you think you can make money in a bear market?

Of course, short selling can be done, but it must be coupled with enhanced risk control and reduced frequency. After all, trading in a bear market is extremely difficult; regardless of being long or short, the risks are epic. Not to mention short selling in a bull market.
