Entered the market in 2016, experienced two rounds of bull and bear markets, achieved financial freedom in 2021, shorted in late March 2022, went long by closing short in late June 2020, took profit on August 15, 2022, and heavily bought the bottom in November-December 2022. Surviving bull and bear markets, winners take all. Buying low and selling high in the right cycles makes profit as simple as breathing.
I. Mathematical principles and risk control models of leveraged trading
The essence of leveraged trading is to leverage excess assets through margin, and its risk calculation formula must include volatility parameters: liquidation threshold = 100% / (leverage multiplier - 1). Taking 100 times leverage as an example, when the asset's volatility reaches 1%, the net value of the margin account will drop to zero, which has the same structure as the futures margin system in traditional financial markets. However, the daily average volatility of cryptocurrencies (BTC about 3-5%) far exceeds that of the stock market (<1%), thus actual risks are exponentially amplified.
Professional traders' leverage choices must match asset volatility:
High volatility cryptocurrencies (such as altcoins, volatility > 10%): only suitable for 1-3 times leverage
Medium volatility cryptocurrencies (such as ETH, volatility 5-8%): recommended 5-10 times leverage
Low volatility cryptocurrencies (such as BTC, volatility 3-5%): maximum leverage not exceeding 20 times
According to OKX exchange data for Q1 2024, users who adopt a dynamic leverage adjustment strategy (automatically reducing leverage with volatility increase) have a liquidation rate 62.3% lower than those using fixed leverage.
II. Quantitative execution system for stop-loss and profit-taking
1. Dynamic stop-loss model
Volatility stop-loss: When the 30-minute candlestick of a single cryptocurrency breaks through 1.5 times the 20-day ATR (Average True Range), a stop-loss order is triggered.
Trend stop-loss: When EMA12 and EMA26 form a death cross, use the lowest price of the last 3 candlesticks as the stop-loss line.
Capital management stop-loss: single trade loss must not exceed 2% of total account funds, so for a principal of 100,000, the maximum stop-loss for a single trade is 2,000.
2. Profit-taking strategy optimization
Partial profit-taking method: Reduce 30% of the first position when reaching the 1.618 Fibonacci extension level, reduce 50% at the 2.618 level, and set a trailing stop for the remaining 20%.
Volatility profit-taking: When a 5-minute candlestick shows a large bullish candle (trading volume reaches more than 3 times the 20-day average) and RSI breaks through 80, trigger partial profit-taking.
In the Bitcoin flash crash event in 2024, users who adopted a composite stop-loss strategy (combining volatility and trend stop-loss) controlled their average losses to 7.2%, while users with a purely fixed ratio stop-loss suffered losses of 10.5%, confirming the advantages of technical stop-loss.
III. Technical indicator synergy system for short-term trading
1. Multidimensional identification during the consolidation period
Determine trend strength through ADX (Average Directional Index): When ADX<25 and lasts more than 15 candlesticks, enter a consolidation period. At this time, it is necessary to combine Bollinger Bands' bandwidth and trading volume: bandwidth contracts to less than 50% of the 20-day average, and trading volume shrinks to 30% of the average volume, indicating that a change in trend window is approaching. Major players often create MACD top divergence/bottom divergence illusions at this stage, which need to be cross-validated with the RSI's overbought and oversold zones (>70 or <30).
2. Technical resonance of reversal signals
Bearish candlestick buying conditions: Must meet (closing price - lowest price) < (opening price - closing price) of 1/3 (body ratio exceeds 70%), while trading volume expands to more than 1.5 times the 5-day average, and it is at the Fibonacci 61.8% retracement level.
Crash rebound threshold: When the 1-hour chart shows 3 consecutive candlesticks with lower shadows (lower shadow length > 2 times the body), and a divergence appears in the OBV energy flow, the rebound probability increases to 78%
IV. Mathematical model for position management
1. Fund allocation formula for pyramid building
Set the initial position as C, with each decline of r (usually taken as 10%), and the position increase ratio as n (recommended 0.5-1), then the total position after the k-th increase is:
C_total = C×(1 + n + n² + ... + nk)
This model can ensure that the average holding cost in the bottom area is 15-20% lower than the market average price, but two prerequisites must be met: the capital pool must be sufficient to support more than 5 times of position increase, and the circulation market value ranking of the selected cryptocurrency must remain stable within the Top 50.
2. Dynamic adjustment of positions in trend trading
When the weekly level breaks through a key resistance level, adopt a volatility position model:
Initial position = total funds × (20% / leverage multiplier)
For each breakout of a resistance level, add positions based on the contraction amplitude of ATR, addition ratio = 20% × (current ATR / ATR at breakout)
V. Verification of the underlying logic of technical analysis
The effectiveness of the Bollinger Bands arbitrage strategy must meet:
Volatility during sideways period (HV20) <15%
Bollinger Bands middle line coincides with EMA50 > 90%
Funding Rate maintained within ±0.01% (no significant long-short divergence)
Backtesting data shows that in 2023, there were a total of 37 arbitrage opportunities for ETH that met the above conditions, with an average single return rate of 4.2%, a winning rate of 73%, and the maximum drawdown controlled at 3.1%.
VI. Quantitative execution plan for trading discipline
Establish a trading log scoring system to quantify the assessment of the following behaviors:
Leverage usage compliance (matching preset volatility standards)
Execution speed after stop-loss trigger (<30 seconds)
Mandatory rest duration after 3 consecutive trading losses (recommended 24 hours)
Whether the holding period in profitable trades conforms to the strategy preset (±10% deviation)
Professional traders' discipline scores usually stay above 85, while accounts with scores below 60 have a 91% probability of negative annual returns. The ultimate battlefield of cryptocurrency trading is not on the candlestick chart, but in the synapses of traders—when technical indicators emit clear signals, whether one can suppress instinctive reactions and execute preset strategies is the core threshold that distinguishes winners from losers.
