The RSI (Relative Strength Index) and the MACD (Moving Average Convergence Divergence) feature in almost all TradingView charts. Each measures something different from the price boost, and used wisely they become an excellent filter for your trading.
What the RSI measures
The RSI compresses the speed of price changes on a scale of 0 to 100. The classic levels are 30 (oversold) and 70 (overbought). When the RSI exceeds 70, the price has risen a lot and fast; when it falls below 30, it has fallen sharply.
The rookie mistake is to buy because the RSI is at 30 or sell because it is at 70 - a strongly trending market can stay overbought for weeks. The mature use is to treat those areas as exhaustion floors that gain value if they are crossed with divergences or with areas of support and resistance.
What the MACD measures
The MACD is constructed with two exponential averages (typically EMA 12 and EMA 26) and a histogram. When the fast line crosses the slow line, the histogram changes color and is interpreted as momentum change. Its value is in detecting Acceleration and deceleration: a histogram that grows confirms momentum; that shrinks anticipates weakness before the price shows it.
| Element | What does it communicate? |
|---|---|
| MACD line on signal | Ongoing bullish momentum. |
| Line under signal | Ongoing bearish momentum. |
| Growing Histogram | The trend accelerates. |
| Decreasing histogram | The trend loses strength. |
| Divergence MACD | Price and momentum mismatch: Spin fuel. |
How to combine them with the price structure
The profitable combination is not “RSI + MACD cross at once,” because that happens late. The solid combination is to cross them with the price context:
- Trend filter: only buys when the price is above the bullish structure (rising lows) or your slow average.
- Push confirmation: that the MACD histogram points in the direction of the plan.
- Exhaustion filter: RSI overbought matching a divergence or liquidity zone is eligible for reversal.
- Input: just when price, RSI and MACD match. Fewer operations, cleaner.
Typical errors
Trade the crosses in side markets (generates erratic inflows and outflows), use RSI/MACD without trend context (buy overbought in strong uptrends), and raise parameters without testing them in the markets where you trade. Defaults (14 and 12/26/9) are a good starting point, but they're not sacred: try, backtest, and adjust to your asset.

Frequently asked questions
What does RSI 70 and RSI 30 stand for?
RSI above 70 indicates overbought (fast and strong rise); below 30, oversold. They are exhaustion notices, not automatic buy or sell signals.
What is the MACD crossover?
When the MACD line crosses the signal line. On the upside, it suggests bullish momentum; on the downside, bearish. In lateral trends it produces many false signals.
Do RSI and MACD work for cryptocurrencies?
Yes, they work in any market. In crypto, where there are violent tendencies, they especially help to detect exhaustion and not to run after already exhausted movements.
What is the best fit for RSI and MACD?
The standard is RSI 14 and MACD (12,26,9). You can test variants according to temporality, but optimize on historical data of your asset, not by eye.
