If your trading principal is less than 3000U, the most important thing now is not to pursue quick doubling, but to learn how to survive steadily in the market.

I have seen an example: starting with 1300U, it reached over 30,000 in four months, without ever blowing up the position or experiencing large fluctuations. The secret is actually very simple—develop three "life-saving" habits.

**First Habit: Capital Segmentation**

The biggest taboo for small capital is to gamble everything on one shot. Divide your funds into three parts: one part for short-term trading, with a maximum of one trade per day; another part waiting for major market moves, which can go untouched for ten days or half a month; and a third part as a safety net, never to be used unless absolutely necessary. The benefit of this approach is that the market always offers opportunities for a turnaround, but once the principal is lost, the game is over.

**Second Habit: Only Trade Markets You Understand**

When the market is sideways or unclear in direction, stay out of the market. It's better to make less profit than to take risks on opportunities you’re not confident about. Honestly, many trading losses come from being restless and itching to operate on ambiguous market conditions.

**Third Habit: Set Trading Rules in Advance**

Trigger your stop-loss and exit immediately—don’t hold on out of luck; take profits when targets are reached—don’t be greedy for the last bit; regularly withdraw a portion of gains when your account grows; never add to losing positions—this helps avoid emotional and reckless operations.

Using these three methods, the account in that example has now exceeded 100,000, and you don’t need to stay up all night watching the screen, living quite comfortably.

Ultimately, trading is like running a marathon. Small-cap players must first ensure their principal doesn’t die—go slow, be steady—only then can they go further.
