Opening Candle Breakout [OCB]
Opening Candle Breakout [OCB]
WHAT IT DOES
OCB marks a single, rule-based setup per session: the direction of the first candle of the trading session. When that candle closes, the indicator draws the entry level, a stop at the opposite side of the candle, and three profit targets expressed in multiples of the initial risk (R). Nothing is repainted: the setup is only confirmed once the first candle has closed.
The idea comes from the opening range breakout family of strategies, and more precisely from the research of Zarattini and Aziz (2023), “Can Day Trading Really Be Profitable?”, which studied the first 5-minute candle on US index ETFs. This script is an independent implementation of that logic, not affiliated with the authors.
HOW IT WORKS
At the close of the first session candle (default 09:30-09:35 New York time), the script checks its direction.
Close above open: long setup.
Close below open: short setup.
Body smaller than the minimum (default 0.5 x ATR): no setup for the day, marked with a grey cross.
The entry level is the close of that candle. Entries are assumed at the open of the next candle.
The stop is placed at the opposite extreme of the first candle (the low for a long, the high for a short). It is bounded between a minimum and a maximum distance expressed in ATR, so that a tiny or a huge opening candle does not produce an unusable stop.
Three targets are drawn at 2R, 5R and 10R by default. In the original research, the position is held until the session close unless a distant target is reached; the targets here are reference levels, you decide how to use them.
Lines are extended while the session is open and stop at the session close. The last N days remain visible for review.
SETTINGS
First session candle: must correspond to exactly one candle of your chart timeframe (09:30-09:35 on a 5-minute chart, 09:30-09:45 on a 15-minute chart, etc.).
Session close and Trading session: used to stop the lines and to close the simulated trade in the statistics.
Timezone: the exchange timezone of the instrument (America/New_York for US indices).
Minimum candle body (x ATR): filters out opening candles without a clear direction. 0 disables the filter.
Minimum / maximum stop (x ATR): bounds for the stop distance.
Targets 1, 2, 3 (R): reference levels.
Days to display: number of past sessions kept on the chart.
ALERTS
Eight alert conditions are available: long setup, short setup, no setup, session close, stop hit, target 1, target 2 and target 3 reached. Create them from the alert dialog with “OCB” as the condition.
STATISTICS TABLE
The table in the top right corner shows the number of setups, win rate, net R, profit factor and average R per trade, computed on the candles loaded in your chart. This is an estimate based on candle highs and lows, with no commissions, slippage or position sizing. It is NOT a backtest and must not be read as a performance claim. Use a proper strategy script with realistic costs before drawing any conclusion. On index futures, this type of setup typically shows a low win rate (around 20 to 25 percent) with a small number of large winning days: this is expected behaviour, not a defect.
WHAT IT IS NOT
It is not a signal service and does not predict direction.
It does not manage position size: risk per trade is your responsibility.
Results vary strongly across instruments and across years. The underlying effect is public and has been documented to weaken over time.
BEST USED ON
5-minute charts of US index futures or ETFs (NQ, MNQ, ES, MES, QQQ, SPY) during the regular session. The script runs on any instrument with a defined session, but the logic was designed for US equity index opens.
