Understanding technical analysis is essential for any serious cryptocurrency trader. Among the most powerful tools available are K-line main chart indicators, which help traders interpret price movements, identify trends, and make informed decisions. In this guide, we’ll explore key technical indicators such as MA, MACD, BOLL, and KDJ, explain their practical applications, and show you how to assess the market control status of various digital assets—critical insights that can significantly improve your trading edge.
Whether you're a beginner or an experienced trader, mastering these tools can elevate your strategy from reactive to predictive. Let’s dive in.

What Are K-Line Main Chart Indicators?
Technical indicators are mathematical calculations based on price, volume, or open interest. They provide traders with visual cues about market sentiment and potential future movements. On platforms like OKX, these indicators are integrated directly into the K-line (candlestick) charts, allowing real-time analysis.
The main chart indicators appear on the same plane as the price chart—unlike sub-indicators (e.g., RSI or volume), which are displayed below. This makes them especially useful for overlaying trendlines and identifying support/resistance levels in conjunction with price action.
Commonly used main chart indicators include:
- Moving Average (MA)
- MACD (Moving Average Convergence Divergence)
- Bollinger Bands (BOLL)
- KDJ Stochastic Indicator
Let’s break down each one.
Moving Average (MA): The Foundation of Trend Analysis
The Moving Average (MA) represents the average closing price of a cryptocurrency over a specified period. By smoothing out short-term volatility, it helps reveal the underlying trend.
For example:
- 5-day MA: Average of the last 5 closing prices
- 10-day MA: Average of the last 10 closing prices
- And so on…
These are typically color-coded:
- Red: 5-day MA
- Yellow: 10-day MA
- Blue: 30-day MA
- Purple: 60-day MA
Types of Moving Averages
- Short-term MA: 5–10 days (ideal for day traders)
- Medium-term MA: 20–30 days (swing traders)
- Long-term MA: 60+ days (position traders and investors)
When shorter MAs cross above longer ones (a "golden cross"), it often signals a bullish trend. Conversely, a "death cross" suggests bearish momentum.

MACD: Gauging Momentum and Trend Reversals
The MACD indicator measures the relationship between two exponential moving averages (EMAs). It consists of three components:
- DIFF: Fast line (EMA12 – EMA26)
- DEA: Slow line (9-day EMA of DIFF)
- MACD Bar: 2 × (DIFF – DEA), shown as histogram bars
Key MACD Signals
- Golden Cross: DIFF crosses above DEA → Buy signal
- Death Cross: DIFF crosses below DEA → Sell signal
- Above Zero Line: Bullish market; look for long opportunities
- Below Zero Line: Bearish market; consider short positions
- Divergence: When price moves opposite to MACD → Potential reversal
For instance, if the price hits a new high but MACD fails to surpass its previous peak, this bearish divergence may warn of weakening momentum.
Bollinger Bands (BOLL): Measuring Volatility and Price Channels
Developed by John Bollinger, this indicator uses standard deviation to create a dynamic price channel consisting of three lines:
- Upper band (resistance)
- Middle band (20-day simple moving average)
- Lower band (support)
How to Use Bollinger Bands
- Price near upper band: Market may be overbought → Watch for pullbacks
- Price near lower band: Market may be oversold → Look for bounce opportunities
- Riding the upper rail: Strong uptrend → Hold long positions
- Riding the lower rail: Strong downtrend → Maintain short bias
- Price around middle band: Consolidation phase → Stay cautious
- Band contraction ("squeeze"): Low volatility → Often precedes big breakouts
A narrowing band often signals an imminent sharp move—traders watch closely for breakout direction.
KDJ Stochastic Indicator: Spotting Overbought/Oversold Conditions
Originally designed for futures trading, the KDJ indicator has become popular in crypto due to its sensitivity to short-term price swings.
It calculates:
- K line: Fast stochastic
- D line: Slow stochastic (moving average of K)
- J line: Reflects deviation from fair value
KDJ Trading Rules
- Overbought zone: D > 80 → Caution for long entries
- Oversold zone: D < 20 → Potential buying opportunity
- Bullish crossover: K crosses above D in oversold area → Buy signal
- Bearish crossover: K crosses below D in overbought area → Sell signal
- Divergence detection: Price makes new high/low but KDJ doesn’t → Reversal warning
- Momentum slowdown: Flattening K/D lines → Possible trend exhaustion
Because KDJ reacts quickly, it's best used alongside other indicators to filter false signals.
How to Check Cryptocurrency Market Control Status
Just like in traditional stock markets, some cryptocurrencies are more heavily influenced by large holders ("whales") than others. Understanding market control status helps assess manipulation risk and liquidity depth.
Think of it this way:
- Highly distributed tokens = harder to manipulate = more reliable price action
- Concentrated holdings = higher risk of pump-and-dump schemes
Step-by-Step: Analyzing Token Distribution (Using USDT as Example)
While Ethereum-based tokens can be checked via Etherscan, let’s focus on general principles applicable across chains:
- Visit a blockchain explorer relevant to the network (e.g., OKLink, Blockchair).
- Search for the token (e.g., USDT).
Review key metrics:
- Total supply
- Number of unique holders
- Top holder distribution (% held by top 10 addresses)
- Transaction frequency
- Click on “Holders” to see address rankings by balance.
🔍 Pro Tip: If a small number of addresses hold most of the supply (e.g., top 5 own >40%), treat that asset with caution—it may be easily manipulated.
Also, beware of naming conflicts: multiple tokens can share the same ticker (e.g., "XPL"). Always verify using the smart contract address.
Only trust projects where tokenomics are transparent and verifiable on-chain.
Frequently Asked Questions (FAQ)
Q: Can I rely solely on MA crossovers for trading decisions?
A: While MA crossovers are useful, they work best when combined with volume analysis and other indicators like MACD or BOLL to confirm signals.
Q: Is MACD better on daily or hourly charts?
A: MACD performs well on both, but daily charts offer stronger, less noisy signals. For scalping, use 1-hour or 4-hour frames.
Q: What does a Bollinger Band squeeze tell me?
A: A squeeze indicates low volatility and often precedes a strong breakout. Wait for confirmed price movement before entering.
Q: How accurate is KDJ for crypto markets?
A: KDJ is highly responsive but prone to whipsaws in volatile markets. Use it with trend filters or longer timeframes to improve accuracy.
Q: Can I check market control status for non-Ethereum tokens?
A: Yes—most major blockchains have explorers (e.g., BscScan for BNB Chain, Solscan for Solana). Always verify the official contract address.
Q: Are centralized exchange listings enough to trust a token?
A: No. Listings don’t guarantee safety. Always conduct independent research on token distribution and development activity.
