How to Read RSI and MACD Together
Two of the most misused indicators in retail trading. Used correctly, RSI + MACD is the confluence base SIGNAL9 builds every technical score on.
What each indicator actually measures
RSI (Relative Strength Index) is a bounded 0–100 momentum oscillator. It answers "is this move stretched?". Above 70 = overbought, below 30 = oversold — but those thresholds only make sense in a range-bound market. In a strong trend RSI can stay pinned in one zone for weeks.
MACD (Moving Average Convergence Divergence) is unbounded. It answers "is the trend accelerating or losing steam?". The signal is the histogram flipping sign, or the MACD line crossing its signal line.
The three high-probability setups
1. Momentum-confirmed pullback (long). Uptrend intact (price above the 50-day MA). RSI dips into 40–50 and turns up. MACD histogram, previously negative, ticks toward zero. You are buying a pullback that is running out of sellers.
2. Bearish divergence (short / exit). Price makes a higher high. RSI makes a lower high. MACD histogram makes a lower high. All three at once = the rally is losing internal support even if price is still up.
3. Reversal off oversold. Price hits a defined support level. RSI closes below 30 then reclaims it on the next bar. MACD histogram flips green. This is the classic "sold too hard" bounce trade.
The trap: RSI overbought does not mean sell
In every major uptrend of the last decade — NVDA 2023–2024, AAPL 2019, BTC 2020 — RSI stayed above 70 on the daily for months. If you shorted every "overbought" signal you got run over. RSI overbought is only actionable when MACD is also rolling over. Alone it means "strong trend", not "top".
How the terminal uses this
SIGNAL9 computes RSI + MACD on multiple timeframes, then only fires a BUY when both align with the primary trend (measured by MA7/MA25/MA99 stacking). That is the "Confluence Score" you see on each pick. Anything below 6 gets filtered out.
FAQ
Is RSI or MACD more accurate?
Neither. RSI measures momentum extremes; MACD measures trend + momentum shift. Used alone each throws false signals. Used together — RSI turning up out of oversold AND MACD histogram flipping positive — the false-signal rate drops sharply.
What RSI level is a buy?
There is no universal level. In a strong uptrend RSI can stay above 60 for weeks and pullbacks bottom near 45–50, not 30. In a downtrend, 30 is a bounce, not a reversal. Read the level relative to the trend.
What settings should I use?
Defaults are fine: RSI 14, MACD 12/26/9. Changing them chases past noise and does not generalize forward. Time-frame matters more than settings — same indicators, 4-hour vs daily, give completely different signals.
