Big Order Candle DetectorBig Order Candle Detector (BOCD) – Explanation & Usage
The Big Order Candle Detector (BOCD) is an indicator designed to identify potential large institutional order activity in the market. It focuses on detecting strong price displacement, which may signal the early stage of a trend.
This structure allows the indicator to capture moments where price moves aggressively, often without overlap with previous price ranges. Such behavior can indicate the presence of strong buying or selling pressure.
How Big Order is Detected
A Bullish Big Order is identified when the current candle’s low is higher than the high of Candle A. This indicates a clear gap or displacement upward, suggesting strong buying interest.
A Bearish Big Order, on the other hand, occurs when the current candle’s high is lower than the low of Candle A, reflecting strong downward pressure.
To reduce noise, the script only marks the first Big Order signal when multiple signals appear consecutively. This ensures cleaner and more meaningful signals.
Visual Representation on Chart
The indicator provides several visual elements to assist analysis:
Triangle Signals
Green triangle → Bullish Big Order
Red triangle → Bearish Big Order
→ Represents early momentum or possible trend initiation
Highlighted Candle (Orange)
→ Considered the origin of the move or liquidity zone
Support & Resistance Box
Drawn based on the high and low of Candle A
→ Acts as a reaction zone for future price movement
Strategy & How to Use
This indicator is best used as a supporting tool for price action analysis, not as a standalone trading signal.
BUY Scenario (Bullish Setup)
When a bullish Big Order appears, it suggests that strong buying momentum has entered the market. Instead of entering immediately, traders typically wait for price to retrace.
Approach:
Wait for price to pull back into the support box, Look for confirmation signals before entering
Confirmation Examples:
Bullish candlestick pattern (e.g., engulfing, pin bar)
Minor break of structure
Increase in volume
Trade Plan:
Entry: Inside the support box (after confirmation)
Take Profit: Nearest resistance zone or previous high
Stop Loss: Below the support box
SELL Scenario (Bearish Setup)
In a bearish setup, the indicator signals strong selling pressure. Similar to the bullish case, traders wait for a retracement rather than chasing the move.
Approach:
Wait for price to move back into the resistance box, Look for signs of rejection
Confirmation Examples:
Bearish rejection candle
Formation of lower high
Weak bullish momentum
Trade Plan:
Entry: Inside the resistance box (after confirmation)
Take Profit: Nearest support zone
Stop Loss: Above the resistance box
