The cruelty of the contract market lies here — passion does not equal full-position gains, and often results in total loss.

Why can some survive long-term here while others are quickly eliminated? Ultimately, it’s not luck but methodology. My survival rule is simply eight words: trial and error decisively, profit wildly.

How to understand? It’s about using small amounts to explore, stopping the loss immediately if wrong; if correct, gradually increasing the position to let profits run fully.

**First Battle: Use 20% of the position to "Scout"**

Never go all-in at the start. My first order always uses only 20% of the total funds; this 20% is your probe. Its purpose is not to get rich quickly but to figure out the true direction of the current market trend. If the market moves against you? It proves your judgment might be off. This loss won’t hurt the fundamentals at all.

Here’s a hard rule: the maximum loss on a 20% position must be controlled within 2% of the total funds. Stop-loss levels must be calculated before opening the position and cannot be vague.

**Accept losses and never hold on stubbornly**

If you lose 10%, exit immediately. I never break this red line. For trades made with 20% of the position, if the price moves against you, instead of clinging to the hope of a rebound, decisively admit you’re wrong. This isn’t cowardice; it’s using the smallest cost to buy the right judgment for the next step.
