High-Probability Scalper (Market Open)

Market open is where volatility is real, spreads are tight, and momentum shows itself early. This scalping strategy is built specifically to operate during that window, filtering out low-quality signals that usually appear later in the session.
Instead of trading all day, the logic is restricted to the first 90 minutes after market open, where continuation moves and fast pullbacks are more reliable.

What This Strategy Does
This script looks for short-term momentum alignment using:

• Fast vs slow EMA structure
  
• RSI confirmation to avoid chasing extremes
  
• ATR-based risk control
  
• Session-based filtering to trade only when volume matters
  

It’s designed for intraday scalping, not swing trading.

Core Trading Logic
1. Market Open Filter
Trades are allowed only between 09:30 – 11:00 exchange time.
This avoids low-liquidity chop and focuses on the period where most breakouts and reversals form.

2. Trend Confirmation

• Bullish bias: 9 EMA crosses above 21 EMA
  
• Bearish bias: 9 EMA crosses below 21 EMA
  

This keeps trades aligned with short-term direction instead of random entries.

3. Momentum Check (RSI)
RSI is used as a quality filter, not as an overbought/oversold signal.
Long trades only when RSI is strong but not extended
Short trades only when RSI shows weakness without exhaustion
This removes late entries and reduces whipsaws.

Entries & Exits
Entries

• Executed only on confirmed candles
  
• No intrabar repainting
  
• One position at a time
  

Risk Management

• Stop-loss based on ATR
  
• Take-profit calculated using a fixed risk–reward ratio
  
• Same structure for both long and short trades
  

This keeps risk consistent across different symbols and volatility levels.

Why This Strategy Works Better at Market Open

• Volume is highest
  
• False breakouts are fewer
  
• EMA crosses have follow-through
  
• RSI behaves more cleanly
  

By not trading all day, the strategy avoids most of the noise that kills scalpers.

Best Use Cases

• Index futures
  
• High-liquidity stocks
  
• Major crypto pairs during active sessions
  
• 1m to 5m timeframes
  

What This Strategy Is NOT

• Not a martingale
  
• Not grid-based
  
• Not designed for ranging markets
  
• Not a “set and forget” system
  

It’s a controlled scalping template meant for disciplined execution.

How to Use It Properly

• Test on multiple symbols
  
• Adjust ATR length for volatility
  
• Tune RSI ranges per market
  
• Always forward-test before live alerts
  

Final Note
This strategy focuses on structure, timing, and risk, not indicator stacking.
If you trade the open, this gives you a clear framework instead of emotional entries.
If you want:

• Alerts
  
• Session customization
  
• News filters
  
• Partial exits
  

You can extend this logic without breaking the core system.
