Overview
This is an intraday trading strategy based on Volume Weighted Moving Average (VWMA) that implements long-short operations through synthetic options combinations. The core of the strategy is the daily-reset VWMA indicator, generating trading signals based on price position relative to VWMA, with automatic position closure before market close. The strategy incorporates robust risk control mechanisms, including position management and trade frequency limitations.
Strategy Principles
The core logic is based on the following points: 1. Using daily-reset VWMA as a dynamic trend indicator 2. Constructing bullish combinations (buy call + sell put) when price breaks above VWMA 3. Constructing bearish combinations (buy put + sell call) when price breaks below VWMA 4. Mandatory position closure at 15:29 (IST) 5. Implementing hasExited variable to control position adding frequency 6. Supporting pyramiding in the direction of breakthrough
Strategy Advantages
- Strong Dynamic Adaptability - Daily VWMA reset ensures indicator reflects current market conditions
- Balanced Risk-Reward - Synthetic options combinations limit risk while maintaining profit potential
- Strict Trading Discipline - Clear entry, position adding, and forced exit mechanisms
- Flexible Position Sizing - Supports percentage-based position management
- Clear Operational Logic - Simple and intuitive signal generation conditions
Strategy Risks
- Choppy Market Risk - VWMA breakouts may generate frequent false signals in ranging markets
- Gap Risk - Overnight large price movements may lead to significant losses
- Options Combination Risk - Synthetic options may have delta neutrality bias
- Execution Slippage - High-frequency trading may face significant slippage
- Capital Efficiency - Daily forced closure increases trading costs
Strategy Optimization Directions
- Introduce volatility filters to adjust strategy parameters in high volatility environments
- Add trend confirmation indicators to reduce losses from false breakouts
- Optimize options combination structure, such as considering vertical spread strategies
- Implement adaptive VWMA periods based on market conditions
- Add more risk control indicators, such as maximum drawdown limits
Summary
This is a well-structured and logically sound intraday trading strategy. It captures short-term trends using the VWMA indicator, combined with synthetic options trading, featuring good risk control mechanisms. Strategy optimization potential mainly lies in reducing false signals, improving execution efficiency, and enhancing risk management systems. While it has certain limitations, it is overall a trading system with practical value.
