In ICT trading methodology, the PD Array—short for Premium and Discount Array—refers to a framework used to interpret how price moves within market structure. It provides a way of analysing price action by categorising reference points such as support, resistance, and liquidity levels. The PD Array is used by traders to place market activity into context rather than relying on isolated signals. This article breaks down what a PD Array is, its components, and how it might be applied within ICT concepts.
An ICT PD array, short for Premium and Discount array, is a concept developed by Michael J. Huddleston, the mind behind the Inner Circle Trader (ICT) methodology. At its core, the PD array is a framework used to organise price levels and zones on a chart where significant institutional activity is likely to occur. These zones highlight areas of interest such as potential support or resistance, points where liquidity resides, or regions that might attract price movement.
The PD array divides the market into two primary zones: premium and discount. These zones may help traders gauge whether the price is above or below its equilibrium, often calculated using the 50% level of a significant price range. In practical terms, prices in the premium zone are typically considered attractive in a downtrend and unattractive in an uptrend, while prices in the discount zone are more attractive in an uptrend and less attractive in a downtrend.
Beyond premium and discount zones, PD arrays include specific elements like order blocks, which are regions linked to institutional buying or selling, and fair value gaps (FVGs), which are imbalances or gaps in price that the market often seeks to revisit. Together, these elements create a structured roadmap for traders to interpret price behaviour.
Unlike a static indicator, an ICT PD array is dynamic and requires traders to interpret price movements in real time, considering the broader market context. It’s not a quick fix but a methodical approach to understanding how price delivers across different levels, offering a clearer view of where high-probability reactions could occur. The PD array is often combined with other ICT concepts, like market structure shifts or SMT divergence, to sharpen analysis.
The foundation of a PD array starts with defining the premium and discount zones. This is typically done by identifying a significant price swing—either a low to a high or vice versa—and applying a Fibonacci retracement. The 50% level of this range serves as the equilibrium point, dividing the chart into two zones:
This equilibrium acts as a baseline, which may help traders assess whether the price is likely to reverse, consolidate, or continue based on its position relative to the 50% mark.
The PD array doesn’t rely on a fixed set of tools. Instead, it offers a collection of components traders can use to refine their analysis. While the choice of tools can vary, they’re often ranked in a loose hierarchy, known as a PD array matrix, based on their importance within the ICT methodology. Let’s break down how this structure works.
Order blocks are areas where institutional traders placed large buy or sell orders, often leading to significant price moves. On a chart, they appear as the last bullish or bearish candle before a sharp reversal. Order blocks are highly prioritised within the PD array because they indicate zones of potential support or resistance.
FVGs are gaps between price levels that form when the market moves too quickly to fill orders evenly. These imbalances create "unfinished business" in the market, and price often revisits these areas to restore balance. They are especially useful for spotting potential reversals or continuation points.
Breaker blocks form when order blocks fail. When supply or demand zones are unable to hold and the market structure shifts, breaker blocks emerge, highlighting levels to monitor.
Mitigation blocks are related to breaker blocks but form after a market structure shift, where the price makes a lower high (in an uptrend) or a higher low (in a downtrend). They function the same as breaker blocks, but the key difference is in the failure of a new high/low before the trend reverses.
Liquidity voids are areas on the chart where there’s little to no trading activity, often following sharp price movements. These large FVGs are often revisited by price as the market seeks to rebalance liquidity, making them significant for identifying future price movements.
ICT rejection blocks are similar in concept to order blocks but consist of the wicks present on a given timeframe where an order block could be drawn. They are essentially a refined version of an order block where the price may reverse.
Old lows or highs represent liquidity pools where traders place stop orders. These levels are magnets for the price, as the market often seeks to trigger these stops before reversing. Identifying these points may help traders anticipate where the price might gravitate.

Let’s consider how the PD array of the ICT methodology might be used.
Before anything else, traders typically assess the broader trend by analysing highs and lows. The goal is to identify the current structure and wait for the market to form a new significant high or low that aligns with the existing trend. For instance, in an uptrend, a trader might wait for a new higher high to form, followed by a retracement.
Once the new high or low is established, traders often draw a Fibonacci retracement tool between the previous low and the recent swing high (or vice versa for a downtrend). This creates a clear division of the price range into premium and discount zones, providing the foundation of the PD array.
As the price retraces within the range, traders watch for it to reach the premium zone in a downtrend or the discount zone in an uptrend. This positioning suggests that the price has reached an area where the risk-reward balance could be more notable.
Within these zones, traders use the tools of the PD array to refine their approach. For instance, an FVG might act as a key level, particularly if it sits just ahead of an order block. Alternatively, a breaker block might signal a potential reversal if the price aligns with the broader trend structure. By combining these elements, traders can narrow their focus to setups that align with both the PD array and the underlying market conditions.
While ICT PD arrays offer a structured framework for analysing price behaviour, they’re not without their challenges. Traders relying on this methodology should be aware of its limitations to avoid potential pitfalls. Here are some important considerations:
ICT PD arrays offer traders a framework for analysing market movements and identifying important price zones. By combining these arrays with other tools and techniques, traders may gain deeper insights into institutional activity.

The ICT PD array meaning refers to a Premium and Discount array, a trading concept developed within the Inner Circle Trader (ICT) methodology. It organises price levels and zones into premium and discount areas, which may help traders analyse where the price is likely to react and reverse and place entry and exit points. The framework includes tools like order blocks, fair value gaps, and liquidity voids to identify potential areas of institutional interest.
A premium array in forex refers to the portion of a price range above its equilibrium level, typically the 50% mark of a significant swing high and low. Traders consider this zone less attractive for buying, as it’s closer to overvaluation, but often look for potential sell trades.
A discount array is the zone below the equilibrium level of a price range. It represents an area associated with potential buying interest, as prices are considered undervalued relative to the swing high and low.
