Entry conditions
Measure the opening range from 09:30–09:35 NY time. Enter on breakout of range high/low with buffer. Volatility filter: ATR must exceed 200 points. Skip if overnight gap exceeds 0.5% (pre-market gap risk avoidance). One trade per session maximum.
Exit conditions
Take profit at 1.5x the opening range size. Stop loss at 0.75x opening range. Close all positions at 12:00 NY time. Emergency close if drawdown on this trade exceeds 2x ATR.

Pine Script vs MQL5: Same Strategy, Different Platforms
| Aspect | Pine Script (TradingView) | MQL5 (MetaTrader 5) |
|---|---|---|
| Execution | Series evaluated on chart updates | Event handlers with explicit buffers |
| Deployment | Runs in TradingView with alerts | Runs in the MT5 terminal or on a VPS |
| Broker access | Via TradingView broker integration | Direct broker connectivity |
| Backtesting | Strategy Tester for strategy scripts | Strategy Tester for Expert Advisors |
| Code complexity | Simpler, functional syntax | C++-like, more powerful |
The calculation can be implemented on either platform, but the runtime model and buffer APIs differ. Read the Pine Script Supertrend reference before porting logic between them.
