I've been observing for a while how many traders get lost in the endless array of indicators and strategies without really knowing which one to use. The truth is, it depends a lot on your investment horizon, but there's one that has worked quite well for me in the long term: the Golden Cross.

Basically, it works like this: you have two moving averages, one short-term and one long-term. When the short-term crosses above the long-term, that's your signal that the market is turning bullish. It sounds simple because it really is, but the power lies in the details.

Most traders I know use the 50 and 200-period moving averages, and there's a reason for that. The 200-day average basically tells you how the asset has behaved over an entire year, while the 50 shows the last two months. When you see the last 50 days surpass the previous 200-day average, it's a very strong indicator that something has changed in the market.

Look, I tested this with the S&P 500 some time ago. The last significant Golden Cross was around July 2020, when the index was at $3,151. If you had bought then and held the position, by January 2022 the index had risen to $4,430. That's nearly $1,280 in profit over 18 months. Of course, then came the death cross in March 2022, and the market turned bearish, but that's the point: if you follow the Golden Cross signal in assets with stable trends like stocks and indices, you have good opportunities.

The important thing is to use this on daily timeframes, not on one-hour or 15-minute charts. If you do it on very short candles, the moving averages won't give you reliable information. And here’s the crucial part: don't trade blindly just based on the Golden Cross. You need to look for confluences with other indicators, check support and resistance levels, look at Fibonacci retracements—anything that gives you more confidence in your entry.

In the example of the S&P 500 I mentioned, if you had entered right after the cross, the market could have reversed quickly and you would have had a false signal. But if you waited for a bounce at the Fibonacci level 0.618 or confirmation at a resistance turned support, your entry would have been much more solid.

Another thing: if you see too many Golden Crosses in an asset, be cautious. It means the indicator isn't reliable for that particular instrument. It's better to have fewer signals that work than many that are false alarms.

In the end, the Golden Cross isn't perfect, but combined with good technical analysis and patience to wait for the best opportunities, it can give you solid long-term results. What you shouldn't do is trade every cross you see. Wait for those that really make sense, look for additional confirmations, and remember that markets like stocks and indices are inherently bullish, so the Golden Cross works better there than in other assets.
