Recently, many people have asked me about master-level adjustments for MACD parameter settings, but in fact, this topic is more complex than it seems.

Many use the default 12-26-9 parameters; this combination is indeed stable, but because of its stability, it can sometimes be a bit sluggish in highly volatile crypto markets. I’ve tried many different combinations myself and have come to understand that MACD parameter settings are not about finding the optimal solution, but about finding the one that best fits your trading style.

First, let’s talk about the standard 12-26-9. The fast EMA (12) captures short-term momentum, the slow EMA (26) observes long-term trends, and the signal line EMA (9) filters out noise. This set of parameters is widely used because the market has formed a certain consensus—everyone watches the same signals, making the reference value more reliable at key moments. The downside is that for short-term traders or those operating in volatile markets, this setup can be a bit too smooth.

Later, I tried the 5-35-5 combination, which reacts much faster and can more precisely catch the start of rallies and declines. But the cost is more noise and false signals. There’s also the 8-17-9, suitable for 1-hour forex charts; 19-39-9, leaning toward medium to long cycles; and 24-52-18, designed for long-term investors. Sensitivity and stability are always a trade-off—there’s no perfect solution.

I conducted a comparative backtest using the 12-26-9 and 5-35-5 on Bitcoin’s daily chart for the first half of 2025. The 12-26-9 generated 7 clear signals, with 2 successful golden crosses leading to gains, and 5 failures. The 5-35-5 produced more than twice as many signals—13 in total—with 5 subsequent significant rises or falls, but also more small fluctuations. Both sets caught the bottom on April 10, but the 5-35-5’s death cross came earlier, resulting in some profit being eaten up.

Here’s a common trap: overfitting. Some people adjust MACD parameters to fit past trends perfectly, but then they use those same parameters to predict the future—backtest results look great, but it’s just using yesterday’s answers to solve today’s problems.

My advice for beginners is to start with the 12-26-9, as it’s the easiest to learn. If you find this set can’t effectively judge market momentum or filter noise, then consider adjusting it. But when you do, be sure to backtest thoroughly to see if the new parameters align with your trading logic. Don’t change them too often—frequent adjustments only confuse you.

Some ask if it’s possible to use multiple MACD setups simultaneously. It’s possible, but it will generate more signals, testing your decision-making skills. Instead of juggling multiple signals, it’s better to find a master-level MACD parameter combination that suits you, and then observe and optimize it over the long term.

Ultimately, MACD is just a tool—there’s no such thing as the absolute best parameters, only those that best fit your trading style. The key is to combine it with your strategy, conduct thorough backtests, and monitor real-time performance. If you notice overfitting, adjust promptly. Technical indicators are always auxiliary; the core still lies in your trading logic and risk management.
