RSI + Stochastic + MACD vs One Indicator: The Combo Was Ahead in 12 of 16 Match-Ups, but Only 1 Gap Was Bigger Than Noise

“Never trade one indicator alone” is repeated so often that few people check it. In the RSI, Stochastic and MACD combo test the three-way agreement passed 0 of 16 runs. That answers whether the combo works. It does not answer the question beginners actually ask: is three still better than one?

So here every single indicator, every pair, and two looser versions of “agreement” run on the same bars with the same stop, target and spread.

What was compared?

• Singles: Stochastic 14, 3, 3 crossing up from below 20 (down from above 80); RSI 14 coming back through 30 or 70; RSI 14 crossing 50; MACD 12, 26, 9 crossing its signal line.
• Pairs: any two of the Stochastic, RSI 50 and MACD events within 6 bars.
• The combo: all three events within 6 bars, entry on the last one.
• Looser agreement: the first bar where all three simply point the same way (RSI above 50, %K above %D, MACD above signal), and the first bar where 2 of 3 do.
• The known benchmark: a 50/200 EMA cross, the rule from the moving average crossover test.
• Noise check: for every match-up I resampled both lists of trades 2,000 times and looked at the gap between the two averages. If the middle 90% of those gaps includes zero, the difference could be the draw of trades and I call it noise.
• Same for all: stop 1.5 ATR, target 3 ATR, 48 bars at most, one trade at a time, 1 pip cost on EURUSD and $0.30 an ounce on gold. EURUSD and gold, June 3 to August 26, 2026, M5 and M15.

Does the combo beat each indicator alone?

Twelve of 16. On a per-trade basis the combo was usually ahead of its own parts, and on gold M15 it was ahead of all four. On EURUSD M5 it was behind two of them, the Stochastic and the plain RSI 30/70 rule.

Now the noise check. Of those 16 gaps, 1 was bigger than noise: the combo against RSI 30/70 on gold M15, +$7.05 a trade with a 90% range of +$1.38 to +$12.90. The other 15 ranges all include zero. On EURUSD M5, with the most trades, the combo’s gap to the Stochastic was -0.26 pips with a range of -0.87 to +0.32. A score of 12 to 4 sounds like a result. Trade by trade, it is not one.

Look at which single was best on each chart: RSI 30/70 on both EURUSD charts, the RSI 50 cross on gold M5, MACD on gold M15. There is no one indicator the combo replaces. And on three of four charts the best single was ahead of the combo. Only on gold M15 did the combo clearly lead: +$3.85 against +$1.08.

Is three better than two?

Nine of 12, and on three charts one pair was ahead of the full combo. Again only 1 gap of 12 was bigger than noise: the combo against Stochastic + RSI on EURUSD M15, +2.73 pips a trade with a range of +0.38 to +5.07. Stochastic + MACD was ahead of the combo on EURUSD M5 and gold M5 and behind it on the other two, all four inside noise. That fits how the three overlap. RSI above 50 and MACD above its signal line agreed on about 7 bars in 10, so the third indicator mostly repeated what the second had said. The fast one plus one slow one already holds most of the information. The Stochastic cross vs MACD comparison shows how different those two are on their own.

Does it matter how you define “agree”?

Most chart templates use the loose version: all three “bullish” at once. That happened on about 4 bars in 10, so it is not a filter at all. It traded four to five times as often as the strict combo and was behind on three charts and level on the fourth. None of those eight gaps was bigger than noise either, so the honest statement is that no way of defining agreement separated itself from the others. The strict form at least trades less.

How does it compare with a moving average cross?

The combo was ahead on three of four charts, and all four gaps were inside noise; the cross trades so rarely that its average is the least certain number on this page. On EURUSD M5, where both had the most trades, the single moving average cross lost -54 pips in total against -337 for the combo, with a third of the trades. The gold M15 cross had only 25 trades. Neither rule passed the random-entry check on any chart.

So what did the extra indicators buy?

Mostly, they bought silence. This is the one effect in the test that is not in doubt: the combo traded 73% to 80% less than the Stochastic it starts from, and each trade pays the spread. On EURUSD M5 the combo’s average was no better than the Stochastic’s (-1.17 against -0.91) and it still lost 624 pips less, purely from sitting out.

That is a real benefit for a beginner who overtrades. It is not an edge. Any filter that skips three trades in four on a losing signal saves pips the same way. Trading costs are why it matters, and they are measured in the tick data vs spread backtest.

Which one should you use?

• If you want fewer, calmer trades: the strict combo does that. Expect about a quarter of the signals of one oscillator.
• If you want one window less on the screen: Stochastic + MACD. Its results could not be told apart from the full combo on any of the four charts.
• Do not expect a better entry from more indicators. In 40 comparisons on this page, 2 gaps were bigger than noise. With a 90% range, about 4 would be by chance alone.
• “All three green” is not a filter. It is true 40% of the time.
• On EURUSD M5 nothing here worked. Every single, pair and combo lost after a 1-pip cost. The earlier indicator combo vs single indicator test asked the same question with other indicators.
• Gold M15 is the lead worth re-testing, on fresh bars and with the settings from the MT5 settings guide.

Frequently asked questions

Is it better to use three indicators than one?

Not measurably. The RSI, Stochastic and MACD combo was ahead of a single indicator in 12 of 16 match-ups, but only 1 of those gaps was bigger than sampling noise. It lost on both EURUSD charts and never beat random entries.

Which two indicators work best together?

Stochastic and MACD are the least alike: one fast, one slow. That pair could not be told apart from the full three-indicator combo on any chart. RSI above 50 and MACD above its signal agreed on about 7 bars in 10, so they mostly repeat each other.

Does combining indicators reduce false signals?

It reduces all signals. The combo took 73% to 80% fewer trades than the Stochastic alone. The share of winners did not improve on EURUSD M5: 30.4% against 34.9%.

Is RSI, Stochastic and MACD better than a moving average cross?

It was ahead per trade on 3 of 4 charts and behind on EURUSD M5 (-1.17 pips against -0.56), but none of the four gaps was bigger than noise.

Why did the combo lose fewer pips if it was not better?

Fewer trades means fewer spreads paid. On EURUSD M5 the combo lost more per trade than the Stochastic but traded 289 times instead of 1,062.
