Opening Range Breakout EA for US100 / NAS100 during the New York session.
This guide walks you through setting up the EA in under 5 minutes. Pure ORB strategy with hard stop loss on every trade. No martingale, no grid, no averaging.
🚀 Step 1: Attach the EA
ONE CHART SETUP!
After purchase, the EA appears automatically in your Navigator under Expert Advisors / Market . Drag it onto a chart of US100 / NAS100 / USTEC — the EA works on M15 timeframe.
You only need ONE chart to run the strategy.
⚙️ Step 2: Enable Algo Trading
In the EA window → Common tab → enable Allow Algo Trading.
Then click the AutoTrading button in the top toolbar to activate live trading.
🔁 Step 3: Check Symbol Names
Make sure the US100 symbol matches your broker exactly.
Examples of broker variants:
-
US100 → on some brokers
-
USTEC → ICMarkets, Pepperstone
-
NAS100 → other brokers
-
NDX100 , USTECm , US100.cash → broker-specific variants
Make sure the symbol is added to your Market Watch.
⚠️ Wrong or missing symbol = the EA cannot operate
🕐 Step 4: Adjust the NY Session Time
The default opening hour is 16:15 (broker server time), which works for most ECN brokers (GMT+2/+3).
If your broker uses a different timezone, adjust the InpSessionStartHour and InpSessionStartMinute inputs to match the actual New York open (15:30 New York time).
Common broker times:
-
ICMarkets / Pepperstone (GMT+3 in winter): 16:15
-
GMT+2 brokers: 15:15
-
GMT+0 brokers: 13:15
⚠️ Verify the session time matches your broker — wrong time means no trades.
⚖️ Step 5: Set Risk Per Trade
Configure your risk through the InpRiskPercent input:
Risk profiles:
-
Conservative → 0.25% per trade
-
Recommended → 0.5% per trade (default)
-
Moderate → 1.0% per trade
-
Aggressive → 2.0% per trade (not recommended)
Maximum 2 trades per day (the second only opens after the first hits stop loss).
🎯 Step 6: Configure Trade Management
The EA includes professional trade management features:
-
Stop Loss → fixed at the opposite side of the range
-
Take Profit → at multiples of risk (default R:R = 1:10)
-
Break-Even → SL moves to entry after a configurable R-multiple
-
Tighten SL → SL tightens after a deeper R-multiple
-
Trailing Stop → activates after price moves 200% of range size
All these features are configurable via inputs and can be turned off independently.
📅 Step 7: Trading Days Filter
Toggle individual weekdays on/off using the day filter inputs. Useful for:
-
Prop firm accounts that disallow Friday trading
-
Skipping holidays
-
Avoiding specific market conditions
By default, all weekdays are enabled.
📊 Step 8: Verify the On-Chart Panel
Once attached, an on-chart panel appears showing:
-
Status — building range / waiting breakout / in trade / closed
-
Range levels — current high and low of the NY opening range
-
Today's trade — direction, entry price, SL, current P&L
-
Stats — total trades, win rate, today's P&L
-
Account info — balance, equity, free margin
Visual range box drawn on the chart shows the High and Low of the first 30 minutes.

📈 The Strategy in 5 Lines
-
Range building — observe the first 30 minutes of NY session, mark High and Low
-
Pending orders — BuyStop above range high, SellStop below range low (OCO logic)
-
Hard stop loss — fixed at the opposite side of the range
-
High R:R — Take Profit at 5–10× the risk for asymmetric returns
-
End-of-day cleanup — pending orders cancelled at 18:00, all positions closed at 23:00
📊 Why It Works
The first 30 minutes of the New York session are when institutional traders, market makers and large funds enter their positions for the day.
The opening range becomes a battlefield between buyers and sellers. The breakout reveals which side won — and the move that follows is often strong and directional.
By entering on the breakout with a fixed stop loss and high R:R, the EA captures these institutional moves without exposure to mean-reversion or news noise.
