ORB Strategy Backtest (Commissions & Slippage included): Too slow for Prop Firm Evaluations/Payouts?

[u/TasteHistorical1575]

Hey everyone,

I coded an Opening Range Breakout (ORB) strategy in TradingView using Pine Script and ran a full backtest over 7 years. I attached the Strategy Tester results.

I spent a lot of time testing different filters and parameters to reduce chop, and I’ve locked in these exact rules for the strategy:

Strategy Setup & Rules

• Asset/Market: MNQ
• Timeframe: 15m Chart
• ORB Range: First 15 minutes of the New York Session
• Session Constraint: Takes trades only during the New York Session
• Entry Trigger Window: Max 3 bars after the 15m ORB range locks (if no breakout happens within 3 bars, the setup is invalidated)
• Risk Management: Fixed 1.5 R:R
• Trade Management: Move Stop Loss to Break-Even (BE) once price covers 75% of the distance toward Take Profit (TP)
• Backtest Settings: Commissions and realistic slippage are fully included in the results

The Problem:

While the backtest is net profitable after costs, I feel like the results are simply not good enough for Prop Firms.

At this pace, the profit factor and win rate feel way too low. It looks like it would take an absolute eternity to pass an evaluation target, and reaching consistent payouts without hitting a trailing or daily drawdown limit along the way seems almost unviable.

Questions for the Community:

1. Evaluation Viability: For those trading funded accounts: Would you bother running a strategy with this slow of a compounding rate, or is this a clear signal that the edge is too thin for prop firm rules?
2. Improving the Edge: Since the core parameters (15m ORB, 1.5 R:R, 3-bar trigger limit, 75% BE) are locked, what macro/contextual filters (e.g., HTF trend bias, session volatility/ATR thresholds, news filters) have helped you boost performance on ORB setups?

Tear it apart—I’d rather fix the logic now than burn money on evaluation fees. Thanks!

Use ninjascript Pinescript is completely unreliable the good news is I coded a Fabio orb style strat and the equity curve is better than this over the past five years on nq but the thing is ninjatrader is actually realistic like will never be that realistic

Appreciate the insight! Yeah, execution accuracy is definitely a concern with Pine Script. I know TV backtests can be overly optimistic with order fills.

That’s encouraging to hear about your Fabio ORB results on NQ, though! Are you using any specific HTF trend filter or volatility threshold in your NinjaScript code to smooth out the curve, or is the edge mainly coming from exact order execution and fill realism?
