Recently, while researching MACD parameter settings, I found that many people are actually using the default 12-26-9, but this set of parameters may not be the most suitable for everyone.

Let me first explain the basic logic of MACD. The fast line (EMA 12) captures short-term momentum, the slow line (EMA 26) observes long-term trends, and the signal line (EMA 9) is used to filter out noise. The reason why 12-26-9 is widely used is mainly because of its stability, and most people in the market are using it. This consensus effect makes key signals more valuable as references. But the problem is, for high-volatility markets like cryptocurrencies, especially for short-term traders, this set of parameters can sometimes be too slow to react.

I’ve tried many MACD parameter combinations myself. For example, 5-35-5 is very sensitive and can catch short-term trends more quickly, but the price is higher for noise, and signals can easily fail. 8-17-9 is somewhere in between, suitable for 1-hour charts. Parameters like 19-39-9 and 24-52-18 are more suitable for medium to long-term swing trading or long-term investing, with fewer signals but higher accuracy.

I previously conducted an interesting comparative experiment, using MACD settings 12-26-9 and 5-35-5 to analyze Bitcoin’s daily chart over about half a year. The 12-26-9 showed 7 clear signals, of which 2 successful golden crosses led to subsequent rises, while the other 5 failed. The 5-35-5 generated 13 signals, with a seemingly higher success rate, but the subsequent price movements were smaller. Interestingly, both sets of parameters caught the starting point of a rally on April 10, but the 5-35-5’s death cross appeared earlier, which actually compressed the profit space.

This highlights a common mistake—overfitting. Some traders deliberately adjust parameters to fit past market data to make backtests look good, but when real trading begins, they end up losing money. My advice is to select a set of MACD parameters and observe it long-term. Only when it truly performs poorly should you consider adjusting, rather than frequently changing parameters.

For beginners, I still recommend starting with the default 12-26-9. But if you find it cannot effectively judge market momentum or filter noise, try adjusting based on your trading habits. Short-term traders might consider 5-35-5 or 8-17-9, but be sure to backtest first—don’t jump straight into live trading. Some advanced traders even use two sets of MACD parameters simultaneously for cross-verification of signals, but that requires higher decision-making skills.

Ultimately, there is no “best” MACD parameter, only the most suitable one for you. The key is to adjust flexibly according to your trading style and market characteristics, and to maintain a habit of review and reflection. Only then can MACD truly become part of your trading system. Blindly chasing the perfect parameters can instead become a stumbling block in your technical analysis.
