The first time someone showed me a hidden order block on a Daily chart, I couldn’t believe I had been ignoring this PD Array my entire trading career. It was sitting right there on every higher timeframe — buried inside two overlapping candlestick wicks — and I’d been walking past it like it was nothing.
An ICT Hidden Order Block is exactly that — a secret PD Array hidden inside overlapping wicks on a higher timeframe. You can’t see it with the naked eye. But once you drop to a lower timeframe inside that wick overlap, a fully formed order block is sitting there.
That’s why we call it “hidden”. It’s a real order block — just camouflaged by the higher timeframe candles.
In this guide, I’ll show you what a hidden order block is, how to spot it in 3 simple steps, how it differs from a regular order block, and exactly how to trade it with CISD or MSS confirmation.
Don’t worry — you don’t need years of experience to find these. Once you know the pattern, you’ll see hidden order blocks on almost every higher-timeframe chart you open.
Ready? Let’s break it down.
What is ICT Hidden Order Block?
An ICT Hidden Order Block is an order block that does not show up clearly on a higher timeframe.
It forms when two same-colour candles overlap each other’s wicks. Inside that wick overlap — on a lower timeframe — an order block has already formed.
So instead of seeing a clean order block candle, you only see overlapping wicks. The institutional order is still sitting there. It is just hidden in plain sight.
The hidden order block is the price range from one wick extreme to the other. For a bullish setup that’s the wick low of the second candle to the wick high of the first candle. For a bearish setup it’s the inverse.
You can see the example of an ICT Hidden Order Block in the picture below:
Hidden Order Block vs Regular ICT Order Block
The quick contrast:
- Regular Order Block: visible on the chart as one candle.
- Hidden Order Block: visible only as overlapping wicks — the actual order block lives on the lower timeframe.
If you’re new to order blocks, read the ICT Order Block guide first (and the bullish / bearish variants), then come back here. The Mitigation Block and Breaker Block are different concepts again — covered in their own posts.
How to Identify an ICT Hidden Order Block
You can spot a hidden order block in three simple steps.
- Find two consecutive same-colour candles. Both bullish for a bullish hidden OB. Both bearish for a bearish one.
- Check for wick overlap. The wick of the first candle and the wick of the second candle must overlap each other.
- Mark the overlap zone. Draw a box from one wick extreme to the other. That’s your hidden order block.
If you drop to a lower timeframe inside that wick overlap zone, you’ll usually see a clean order block formed there. That’s the institutional footprint the higher timeframe is hiding.
With identification down, here are the two types you’ll find on a chart.
Types of ICT Hidden Order Block
There are two types based on market direction.
(I) Bullish Hidden Order Block
A bullish hidden OB forms when two consecutive bullish (green) candles overlap their wicks.
The first candle has an upper wick. The second candle has a lower wick that overlaps with the first candle’s upper wick.
Mark the box from the low of the second candle’s wick to the high of the first candle’s wick. That whole range is the bullish hidden order block.
You can see the example of bullish hidden order block in the picture below:
(II) Bearish Hidden Order Block
A bearish hidden OB forms when two consecutive bearish (red) candles overlap their wicks.
The first candle has a lower wick. The second candle has an upper wick that overlaps with the first candle’s lower wick.
Mark the box from the high of the second candle’s wick to the low of the first candle’s wick. That’s your bearish hidden order block.
You can see an example of a bearish hidden order block in the picture below:
Now that you can spot both types on a chart, let’s look at why hidden order blocks behave the way they do.
Hidden Order Block as a PD Array
The hidden order block is part of the wider ICT PD Array Matrix — that guide covers the full hierarchy and why price returns to PD Arrays.
For the hidden OB specifically, two things are worth knowing inside this post:
Proximal and distal lines. The proximal line is the side of the hidden OB closest to current price. The distal line is the far side. You enter near the proximal line and place your stop beyond the distal line.
Where it sits in the range. A bullish hidden OB sitting in discount is a strong long signal. A bearish one sitting in premium is a strong short.
With the why out of the way, let’s pin down the timeframes.
Best Timeframes for ICT Hidden Order Block
Hidden order blocks form on every timeframe. But they’re most reliable on higher timeframes.
- Bias timeframe: Daily or 4-hour for swing trades. 1-hour for intraday.
- Hidden OB timeframe: the same higher timeframe you use for bias.
- Confirmation timeframe: 5-minute or 15-minute to spot CISD or MSS once price taps the hidden OB.
The bigger the timeframe of the hidden OB, the bigger the move it tends to drive. A Daily hidden OB will usually push price further than a 1-hour one.
Now you know which timeframes to use. Let’s walk through the actual trade.
How to Trade ICT Hidden Order Block (Step by Step)
Trading a hidden order block follows the same flow as any PD Array trade. Here’s the exact sequence.
- Set your higher timeframe bias. Decide if you’re looking for longs or shorts based on institutional order flow and your daily bias.
- Mark your hidden order block. Find the overlapping wicks on your bias timeframe and draw the box.
- Wait for price to retrace. Don’t chase. Let price come back to tap the hidden OB.
- Drop to a lower timeframe for confirmation. Once price enters the hidden OB zone, switch to 5m or 15m.
- Look for CISD or MSS. A Change in the State of Delivery (CISD) or a Market Structure Shift (MSS) in your direction confirms the trade.
- Enter the trade. Take entry on the close of the CISD/MSS candle or on a clean retest of it.
- Place your stop loss. Below the CISD/MSS swing low for longs. Above the swing high for shorts. For a wider stop, place it just beyond the distal line of the hidden OB itself.
- Set your target. Aim for the next opposing PD Array, the next liquidity pool, or use a fixed risk-reward like 1:3.
Bonus Tip: Combine Hidden Order Blocks with Liquidity Sweeps
The highest-probability hidden OB trades happen right after a liquidity sweep.
The setup: price sweeps liquidity above a swing high (for shorts) or below a swing low (for longs), then retraces back into the hidden order block. The sweep clears the early entries. The hidden OB delivers the institutional fill. CISD on the lower timeframe gives you the entry trigger.
When all three line up — sweep, hidden OB, lower-timeframe confirmation — the win rate jumps significantly.
Frequently Asked Questions
What is a hidden order block in ICT trading?
A hidden order block is an order block that’s not visible on the higher timeframe but is hiding inside the overlapping wicks of two same-colour candles. The actual order block lives on the lower timeframe inside that wick overlap.
How is a hidden order block different from a regular ICT order block?
A regular order block is a single visible candle. A hidden order block is two candles whose wicks overlap, with the real order block tucked inside that overlap on a lower timeframe.
Which timeframe is best for hidden order blocks?
Daily and 4-hour are the most reliable for swing trades. For intraday trades, mark hidden OBs on the 1-hour and confirm on 5-minute or 15-minute.
Is a hidden order block a PD array?
Yes. The hidden order block sits inside the PD array family alongside regular order blocks, fair value gaps, breakers, and mitigation blocks.
Where should I place my stop loss on a hidden order block trade?
The tighter stop is below the CISD or MSS swing low for longs (above the swing high for shorts). The wider stop sits just beyond the distal line of the hidden order block itself.
Is a hidden order block the same as a suspension block?
No. A suspension block is a separate PD array introduced by ICT in September 2025. Both are “hidden” PD arrays in the sense that they don’t show up obviously on the chart, but the formation rules are different. See our ICT Suspension Block guide for the full breakdown.
Wrapping Up
We hope this guide helped you understand the ICT Hidden Order Block and how to trade it with confidence.
The hidden order block is one of the most underrated PD Arrays — most retail traders ignore it because they only look at the higher timeframe. Now you know better.
Mark a few hidden OBs on your charts this week. Once you see them, you can’t unsee them.
thankyou
it,s work ??
Yes, Amit, the Hidden Order Block works. It is most reliable on Daily and 4-hour timeframes, and the highest-probability setups occur when the wick-overlap zone also contains a fair value gap or order block on the lower timeframe. Skip Hidden OBs that form during low-liquidity sessions like the Asia lunch hour — they often fail.

Thank yo very much sir the info is helpful!
Thank you, Idongesit. Glad it helped.
bro pls post about ict reaper fvg
Done. The ICT Reaper Inversion Fair Value Gap guide is live now: https://innercircletrader.net/tutorials/ict-reaper-inversion-fair-value-gap/ . It covers what the Reaper IFVG is, why price so often runs past the Breaker Block before it gets there, and the full bullish and bearish trade flow step by step.
