Formula: Bullish OB: Zone = higher of Open/Close down to Low | Bearish OB: Zone = High down to lower of Open/Close | Midpoint = (Top + Bottom) / 2
Worked example — Bullish OB: 1.0865–1.0880 | Midpoint: 1.08725 | Invalidation: 1.0865
Formula
Bullish OB: Zone = higher of Open/Close down to Low | Bearish OB: Zone = High down to lower of Open/Close | Midpoint = (Top + Bottom) / 2
For a bullish order block, the zone extends from the candle's open (or close, whichever is higher) down to its low. For a bearish order block, the zone extends from the candle's high down to the lower of its open and close, which on the up candle that forms a bearish order block is its open. The midpoint is the average of the zone's top and bottom, serving as a precision entry level.
Worked Examples
Example 1: Bullish Order Block on EUR/USD
Problem:Last down candle before up move: Open 1.0880, Close 1.0870, High 1.0885, Low 1.0865. Calculate the OB zone.
Solution:OB Top = Open (higher of open/close) = 1.0880 OB Bottom = Low = 1.0865 Midpoint = (1.0880 + 1.0865) / 2 = 1.08725 OB Size = 1.0880 - 1.0865 = 15 pips Invalidation = Below 1.0865
Result:Bullish OB: 1.0865–1.0880 | Midpoint: 1.08725 | Invalidation: 1.0865
Example 2: Bearish Order Block on GBP/USD
Problem:Last up candle before down move: Open 1.2740, Close 1.2760, High 1.2770, Low 1.2735. Calculate the OB zone.
Solution:OB Top = High = 1.2770 OB Bottom = Open (lower of open/close, since this up candle opened at 1.2740 and closed at 1.2760) = 1.2740 Midpoint = (1.2770 + 1.2740) / 2 = 1.2755 OB Size = 1.2770 - 1.2740 = 30 pips Invalidation = Above 1.2770
Result:Bearish OB: 1.2740–1.2770 | Midpoint: 1.2755 | Invalidation: 1.2770
Frequently Asked Questions
What is an Order Block in ICT trading?
An Order Block (OB) is a specific price zone identified in ICT (Inner Circle Trader) methodology that represents the last opposing candle before a significant price movement. For a bullish order block, it is the last bearish (down) candle before a strong bullish impulse move that breaks market structure to the upside. For a bearish order block, it is the last bullish (up) candle before a strong bearish impulse move that breaks structure to the downside. Order blocks represent areas where institutional traders and market makers placed large orders, creating a supply or demand zone that price is likely to revisit. They serve as high-probability entry zones when price returns to them.
How do you identify a valid Order Block?
A valid order block must meet several criteria in ICT methodology. First, the candle must be the last opposing candle before an impulsive move. Second, the impulse move following the OB must cause a break of market structure, meaning it takes out a significant swing high or swing low. Third, the order block should ideally contain a fair value gap within or near it for added confluence. Fourth, volume analysis should show increased activity around the OB candle. An order block that does not lead to a structure break is not considered valid. Higher timeframe order blocks carry more significance than lower timeframe ones, and order blocks aligned with the overall trend direction have higher success rates.
What is the Order Block midpoint and why does it matter?
The Order Block midpoint, also known as the mean threshold or 50% level of the OB, is calculated by averaging the top and bottom of the order block zone. This level is significant because institutional algorithms often target the midpoint for order fills rather than the extreme edges. When price returns to an order block, it may only reach the midpoint before reversing, especially in strong trending markets. Traders who place entries at the midpoint get a better fill compared to those waiting at the extreme edge, though the probability of getting filled is slightly lower. Using the midpoint allows for tighter stop losses and improved risk-to-reward ratios on OB trades.
When is an Order Block considered invalidated?
An order block is considered invalidated when price closes through the entire zone on the opposite side. For a bullish order block, invalidation occurs when price closes below the low of the OB candle, indicating that the demand zone has been broken and the institutional orders have been absorbed. For a bearish order block, invalidation happens when price closes above the high of the OB candle. It is important to note that a wick through the OB extreme does not necessarily invalidate it — only a candle close beyond the level confirms invalidation. Once an OB is invalidated, the zone may flip from support to resistance or vice versa, creating a potential trap for traders still holding positions.
How do you trade Order Blocks with proper risk management?
To trade an order block effectively, first identify a valid OB on a higher timeframe that aligns with your bias. Drop to a lower timeframe to refine your entry within the OB zone. Place your entry at the OB midpoint or at the extreme edge depending on your risk tolerance. For bullish OBs, set your stop loss 1-3 pips below the OB low (the invalidation level). For bearish OBs, place it 1-3 pips above the OB high. Target the opposing liquidity pool, the next order block, or use a minimum 1:3 risk-reward ratio. Never risk more than 1-2% of your account per OB trade. Use additional confluence like fair value gaps, OTE levels, and killzone timing to increase the probability of success.
What is the difference between an order block and a fair value gap?
An order block is a single candle's zone, the last opposing candle before the impulse, while a fair value gap is an imbalance spanning three candles: the untraded space left when the first candle's high and the third candle's low fail to overlap. The order block marks where orders were placed; the gap marks where price moved too quickly to trade fairly. They frequently overlap, and an order block containing a gap is the higher-confluence version of the setup.
Why does a bullish order block run from the open rather than the close?
A bullish order block is the last down candle before the impulse, so by definition its open sits above its close. The calculator takes the higher of open and close as the zone top and the candle low as the bottom, which captures the whole bearish body plus the lower wick. On the sample candle, with open 1.0880, close 1.0870 and low 1.0865, that produces a zone of 1.0865 to 1.0880.
Should the zone include the wick or only the candle body?
Including the wick gives a wider zone and a better chance of being filled, while using the body alone gives a tighter stop but is missed more often. On the sample bullish candle, open to low spans 15 pips whereas open to close spans only 10, so the body-only version cuts stop distance by a third and lets position size rise in proportion. Choose one convention and apply it to every chart.
What is a breaker block, and when does an order block become one?
A breaker forms when price trades cleanly through an order block instead of respecting it, so a zone that failed as demand is afterwards watched as supply, or the reverse. Traders then wait for price to return to the broken zone from the other side and trade in the direction of the break. The practical difference is polarity: on an order block you fade the retracement, on a breaker you side with the move that destroyed it.
How does the pip size setting change the zone measurement on yen pairs or gold?
Zone width in pips is the price span divided by the pip size, so the selector matters. Most pairs quote a pip as 0.0001, but yen crosses and gold move in 0.01 increments. An order block on USD/JPY running from 147.20 to 147.50 covers a 0.30 price span, which is 30 pips at the 0.01 setting but would be reported as 3,000 if the 0.0001 setting were left in place.
