Order Block Details
Formula
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 its close (or open, whichever is lower). The midpoint is the average of the zone's top and bottom, serving as a precision entry level.

Background & Theory
The Order Block Finder applies the following established principles and formulas. Foreign exchange markets facilitate the conversion of one currency into another and serve as the largest and most liquid financial markets in the world, with daily turnover exceeding seven trillion US dollars. Exchange rates are quoted as currency pairs, expressing the price of one unit of a base currency in terms of a quote currency. For example, a EUR/USD rate of 1.0850 means one euro buys 1.0850 US dollars. The smallest standardized price movement in most pairs is the pip, typically the fourth decimal place, with a value of 0.0001 per unit for USD-denominated pairs. The bid price is the rate at which a dealer will buy the base currency, while the ask price is the rate at which it will sell. The spread between bid and ask represents the dealer's compensation and varies with liquidity and volatility. Leverage amplifies both gains and losses by allowing traders to control positions larger than their deposited margin. A 100:1 leverage ratio means a one-percent adverse move eliminates the entire margin, making position sizing and risk management critical. Two parity conditions from international economics anchor exchange rate theory. Purchasing Power Parity (PPP) holds that exchange rates should adjust over time so that identical goods trade at equivalent prices across countries: S = P_d / P_f, where S is the spot rate and P_d and P_f are domestic and foreign price levels. PPP performs well over long horizons but poorly in the short run due to trade barriers, non-tradable goods, and capital flows. Covered Interest Rate Parity (CIRP) is a near-arbitrage condition stating that forward exchange rate premiums or discounts exactly offset interest rate differentials between two currencies: F/S = (1 + r_d) / (1 + r_f). Deviations from CIRP create riskless arbitrage opportunities that traders rapidly eliminate. Uncovered Interest Rate Parity posits that high-yielding currencies should depreciate to offset their interest advantage, though empirical evidence is mixed and the carry trade — borrowing in low-rate currencies to invest in high-rate ones — has generated persistent returns.
History
The history behind the Order Block Finder traces back through the following developments. For much of the nineteenth century and early twentieth century, the international monetary system operated under the classical gold standard, under which each participating currency was fixed to a defined weight of gold, making bilateral exchange rates effectively constant. The system provided price stability and facilitated global trade but constrained governments' ability to respond to economic downturns. World War One shattered the gold standard as nations suspended convertibility to finance wartime expenditures. The interwar period saw attempts to restore gold convertibility, most notably the British return to the gold standard in 1925 at the pre-war parity, a decision criticized by John Maynard Keynes as deflationary. The Great Depression forced widespread currency devaluations and the effective collapse of the international gold standard by the early 1930s. The Bretton Woods Conference of July 1944 established a new order in which member currencies were pegged to the US dollar, while the dollar alone was convertible into gold at 35 dollars per troy ounce. The International Monetary Fund and World Bank were created at the same conference to oversee the system. Bretton Woods delivered exchange rate stability during the postwar growth era but came under strain as US deficits and European dollar accumulation outpaced American gold reserves. On August 15, 1971, President Nixon announced the suspension of dollar-gold convertibility — the so-called Nixon Shock — effectively ending the Bretton Woods system. By 1973, major currencies had transitioned to floating exchange rates determined by market supply and demand, a regime that has persisted. On September 16, 1992, hedge fund manager George Soros shorted the British pound against the European Exchange Rate Mechanism constraints, forcing the UK's withdrawal in what became known as Black Wednesday. Electronic trading platforms emerged in the 1990s and 2000s, replacing voice-brokered interbank markets and dramatically reducing transaction costs for institutional and retail participants alike.
Frequently Asked Questions
Formula
Bullish OB: Zone = Open to Low | Bearish OB: Zone = High to 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 its close (or open, whichever is lower). 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\nOB Bottom = Low = 1.0865\nMidpoint = (1.0880 + 1.0865) / 2 = 1.08725\nOB Size = 1.0880 - 1.0865 = 15 pips\nInvalidation = 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\nOB Bottom = Close (lower of open/close) = 1.2740\nMidpoint = (1.2770 + 1.2740) / 2 = 1.2755\nOB Size = 1.2770 - 1.2740 = 30 pips\nInvalidation = 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 a market order and a limit order in forex?
A market order executes immediately at the current price. A limit order sets a specific price at which you want to enter or exit. Buy limits are placed below the current price; sell limits are placed above. Limit orders help you enter at more favorable prices but may not fill.
