#TradFi交易分享挑战 A 200-day moving average, allowing him to make $100 million in one day!

Imagine this: if you could make $100 million in a single day, how would it feel? According to reports, Paul Tudor Jones, one of Wall Street's top traders and one of the world's most famous macro traders, achieved such astonishing results during the 1987 US stock market crash. But the truly interesting part isn't just how much he made, but that his trading logic is actually very simple. The tool he used was the 200-day moving average. In his trading system, the 200-day moving average isn't just an ordinary indicator; it's one of the core defensive tools in his entire risk management framework. He has publicly stated, "The standard I use to measure all markets is the 200-day closing price moving average." One of the most widely circulated quotes in trading circles from Paul Tudor Jones is: "Nothing good happens below the 200-day moving average."

A more classic quote is: "I've seen too many stocks and commodities eventually fall close to zero. Therefore, I believe the most important question in investing isn't 'How do I make big money?' but 'How do I avoid losing everything?' My solution is very simple: when the price falls below the 200-day moving average, exit the market and switch to a defensive mode."

His rules are very straightforward:
✔ When the price is above the 200-day moving average, continue holding the position or stay invested.
✔ When the price falls below the 200-day moving average, exit the market. In other words, if the price is above the 200-day moving average = buy or hold long positions; if the price is below the 200-day moving average = sell or stay on the sidelines. This seemingly simple rule can help traders avoid some of the most severe market crashes and effectively protect capital when the trend turns negative.

Why is the 200-day moving average so important?
The 200-day moving average isn't some magical formula. It isn't always effective and can produce false signals. But it has an extremely important advantage: it helps you stay disciplined. You don't need to guess the market, predict the future, or be driven by emotions. You just need to follow a clear rule.
When the market is above the long-term trend line, you participate. When the market breaks below the long-term trend line, you proactively reduce risk. It's that simple. And this simplicity is why the 200-day moving average strategy has withstood decades of market tests and is still widely used by countless traders and investors.
Many times, you don't need a complicated system. A simple and clear rule is enough to keep you on the right side of the trend. $US500500 ‌$NAS100 ‌
