The following is a strategic framework for long position investment in cryptocurrency contracts, integrating EMA trend analysis as the core, supplemented by MACD and RSI verification logic, for reference:
I. Trend Judgment: EMA as the Core
Strategy Logic:
EMA (Exponential Moving Average) is the core tool for trend tracking, judging trend direction through the crossover and arrangement of short-term and long-term EMAs.
Parameter Recommendations:
Short-term EMA: 7-20 period (capture short-term trends)
Long-term EMA: 50-200 period (confirm long-term trend)
Operational Rules:
1. Trend Confirmation:
Long Position Signal: When the short-term EMA (e.g., EMA20) crosses above the long-term EMA (e.g., EMA50), and the price stabilizes above EMA50, it is determined to be an uptrend.
Trend Continuation: Price remains above EMA20/EMA50, and EMA is in a bullish arrangement (short > medium > long).
2. Pullback Entry:
In an uptrend, if the price retraces to EMA20 or EMA50 (not breaking below), consider it a low-risk long entry opportunity.
Combine volume expansion to verify support effectiveness.
II. Momentum Verification: MACD Assistance
Strategy Logic:
MACD (Moving Average Convergence Divergence) is used to confirm trend strength and potential turning points.
Key Signals:
1. Golden Cross/Death Cross:
MACD line (fast line) crosses above the signal line (slow line) → Long position enhancement signal (must be consistent with EMA direction).
If the golden cross appears above the MACD zero line, bullish momentum is stronger.
2. Divergence Signals:
New price high, MACD not at new high → Potential top risk (beware of pullback).
New price low, MACD not at new low → Potential bottom signal.
Operational Rules:
Adding Long Position: MACD histogram continues to expand and is above the zero line.
Take Profit Alert: When MACD histogram decreases or a top divergence appears, partially take profit.
III. Overbought/Oversold Filtering: RSI Assistance
Strategy Logic:
RSI (Relative Strength Index) is used to avoid blindly chasing long positions in the overbought zone, or to find opportunities during pullbacks.
Parameter Recommendations:
Period: 14 (default)
Threshold: Overbought zone (above 70), Oversold zone (below 30)
Operational Rules:
1. RSI Application in Uptrends:
If RSI >70: do not directly short, but partial take profit; if the price continues to rise and EMA is not broken, the overbought signal can be ignored.
Pullback Opportunity: RSI falls to around 50 (trend midline), and EMA support is effective, considered as a point for adding long positions.
2. RSI Application in Volatile Markets:
RSI <30 + price bounces back → Short-term rebound signal (must be filtered with EMA trend).
IV. Long Position Strategy Integration
Step Example:
1. Trend Confirmation:
EMA20 > EMA50 > EMA200, price is above EMA20.
2. Momentum Verification:
MACD golden cross and above the zero line, histogram continues to expand.
3. Entry Timing:
Price retraces to EMA20/EMA50, RSI falls to the 50-60 range.
4. Risk Management:
Stop Loss: 2%-3% below EMA50 (or previous low support level).
Take Profit: Tiered take profit (e.g., Target 1: previous high resistance; Target 2: trend line breakout).
V. Precautions
1. Characteristics of Cryptocurrency:
In high volatility, need to enlarge stop-loss space to avoid triggering stop-loss during short-term fluctuations.
Major events (e.g., regulation, hacking) can instantly destroy technical signals, requiring caution in conjunction with fundamentals.
2. Parameter Adjustment:
Adjust EMA period based on the volatility of the currency (e.g., use EMA50 for BTC, EMA20 for altcoins).
3. Backtesting Verification:
Historical data backtesting + live small capital verification, avoid overfitting.
Summary:
Using EMA trend as the framework, MACD for momentum verification, and RSI as a pullback filter, the success rate of long positions is high when all three resonate. Strictly enforce stop-loss discipline to avoid excessive leverage in a single market situation.
