I have 8 years of experience in trading. I am a trend follower and I trade mostly using the Turtles method.
Because the markets have changed since the 80s, I use longer periods for breakouts and trailing stops, no pyramiding, and a bigger ATR multiple as stop loss. - Version: 1.4

Patterns and Opening Range Breakout"
The NR7 ORB EA automates one of the most time tested intraday concepts in technical analysis: identifying periods of extreme price compression and trading the breakout when the market finally moves.
Each session, the EA scans for an NR7 bar — a candle whose range is narrower than each of the previous 6 bars, signaling that the market has coiled into a tight compression zone. Once a valid NR7 is confirmed, the EA arms itself and watches price in real time. The moment price crosses at least 1 pip beyond the compression high or low, a trade is triggered in the direction of the breakout.
The stop loss is placed at the opposite end of the compression zone, giving the trade a clearly defined risk boundary from the moment of entry. All positions are closed at the end of the trading session. This is a pure intraday system with no overnight exposure.

How the Logic Works
Step 1 — Session detection (automatic)
The EA reads your broker's actual market hours using SymbolInfoSessionTrade(). No manual session configuration needed. It adapts automatically to Forex (24h), metals, crypto, and oil schedules.
Step 2 — NR7 scan (once per bar)
On each new bar, the EA checks whether the most recently closed candle is narrower than the previous 6 candles. If yes, the high and low of the entire 7 bar window define the compression zone.
Step 3 — Breakout trigger (every tick)
Once armed, the EA monitors price continuously. A buy is triggered when the ask crosses 1 pip above the compression high. A sell is triggered when the bid crosses 1 pip below the compression low.
Step 4 — Session-boundary protection
The EA will not open a new trade on the last candle of the session. All open trades are closed at session end — no rollovers, no overnight gaps.
Step 5 — Risk-based position sizing
Lot size is calculated using OrderCalcProfit() to match your exact risk percentage to the stop distance, accounting for instrument specific contract sizes and broker conditions.

What It Is (and Isn't)
This EA is built for traders who want a rules based, mechanical intraday system with a clear edge: volatility compression followed by directional breakout. It does not use martingale, grid, or averaging. Every trade has a fixed stop loss defined before entry. Risk is controlled and consistent.
If you are looking for a high frequency scalper this is not it. This EA takes in general one or two trades per day if you trade on 30 minutes time frame, per instrument — quality over quantity.
Before using on a live account, test thoroughly in the Strategy Tester and on a demo account. Trading involves risk of loss. Past performance is not indicative of future results.
