This strategy combines VWAP, EMA and RSI for trend bias and follows trends using a trailing stop approach. It aims to ride trends with adaptive exits.

Strategy Logic:

1. Calculate VWAP as fair value benchmark.

2. Compute 15-period EMA as intermediate-term trend indicator.

3. Use RSI to identify overbought levels, RSI above threshold signals bullishness.

4. Enter long when close exceeds VWAP and EMA, and RSI overbought.

5. Set trailing stop loss line certain percentage below entry point.

6. Take fixed profit at set point level to lock in gains.

Advantages:

1. VWAP, EMA and RSI improve entry accuracy from multiple aspects.

2. Trailing stop moves dynamically to protect profits.

3. Fixed profit-taking provides certainty in exiting.

Risks:

1. RSI and EMA prone to false signals during ranges.

2. Stop loss calibration requires prudence, too wide or too narrow problematic.

3. No limit on single trade loss size.

In summary, this strategy combines multiple indicators and uses a trailing stop for trend following. It performs well in sustained trends but requires optimization and risk controls.
