Order block (OB)

An order block is the last opposing candle before a strong move away: the final down candle before a rally, or the final up candle before a drop. Traders mark it as a zone price may come back to, and use it as an entry area with the stop just beyond it.

A falling price path ends in one down candle, then a large up candle breaks above the last swing high. The down candle is boxed in gold and labelled bullish order block. Price later returns into the box, with the entry at the top of the body and the stop below the wick.
A bullish order block: the last down candle before a strong move up that breaks the last swing high. The zone runs from its body to its wick; a close below the wick means it failed.

How to find one

Start from the move, not the candle. Find a strong push that breaks structure: a break of structure or a change of character. Then step back to the last candle that went the other way before it started.

  • Bullish order block: the last down (red) candle before a strong rally. It is a possible buy zone if price returns.
  • Bearish order block: the last up (green) candle before a strong drop. It is a possible sell zone.
  • Several candles: if two or three same-colour candles sit before the move, most traders box them as one zone.

The usual explanation is that large traders filled part of a position there and may defend or add to it on a return. That is a story about why it might work; a chart can't show whose orders were filled.

Where traders disagree

The order block comes from ICT and smart-money teaching, and it has no single rule book. Three choices change what you mark:

  • Body or wick. Wick to wick is the widest zone; the body alone is the tightest. Planning the entry from the body and the stop beyond the wick is a common compromise.
  • How strong the move must be. Some want only a large candle; others also want a break of structure, a liquidity sweep just before it, or a fair value gap left behind.
  • When it is used up. Many traders count a block once: after the first touch it is "mitigated". Others keep it until price closes through its far side.

StraviFX's glossary uses the plain version: the last opposing candle before an aggressive move away. Use the filters you like, but use the same ones every time, or your journal can't tell you whether they work.

A worked example

A 4-hour EUR/USD chart. The prices are an illustration, not real data.

  • The block: after a dip, the last down candle opens at 1.0912, trades between 1.0918 and 1.0884, and closes at 1.0890. The next candle rallies to 1.0975 and closes above the last swing high at 1.0950. That down candle is a bullish order block, with a body of 1.0890–1.0912 and a wick low of 1.0884.
  • Entry at the top of the body: a buy at 1.0912 when price returns, with the stop at 1.0879, 5 pips below the wick (33 pips of risk). The target is the new high at 1.0975, 63 pips away: a 1:1.91 risk-to-reward. On a $1,000 account risking 1% ($10), 33 pips at $10 a pip per standard lot gives 0.03 lots, risking $9.90.
  • Entry at the middle of the block: a buy at 1.0901, halfway between 1.0918 and 1.0884, with the same stop, risks 22 pips for 74: 1:3.36, and 0.04 lots risking $8.80. Better numbers, but price may turn at 1.0912 and never fill the order.

A deeper entry improves the ratio and lowers the chance of a fill. The lot size calculator resizes the trade for whichever stop distance you choose.

Why it matters

An order block gives a pullback trade two things a beginner usually lacks: a specific area to wait for instead of chasing the move, and a clear point where the idea is wrong (beyond the far side of the block). That makes the stop a structural decision rather than a guess, and the lot size follows from it.

Common mistakes

  • Marking every opposite candle. Every rally starts after some down candle. Without a strong move that breaks structure, it isn't an order block.
  • Buying a bullish block in a downtrend. A block against the higher-timeframe trend is often run straight through. Check the bigger picture first.
  • Putting the stop inside the block. Price often trades deep into the zone before turning. A stop at the middle gets taken on a normal test.
  • Trading the third or fourth touch. Each visit uses up whatever orders were there. The first return is the one most traders plan for.

Questions

Do you mark an order block from the wicks or the bodies?

Traders disagree. Wick to wick gives the widest zone and catches more touches; bodies only is tighter and misses more. A common middle way plans the entry from the body and puts the stop beyond the wick, because a move past the wick means the block has failed.

What makes an order block valid?

There is no standard test. Most definitions want the move away to be strong (a large candle, often called displacement) and to break structure. Many also prefer that the move left a fair value gap. A down candle before a weak drift higher is just a candle, not an order block.

What does it mean when an order block is mitigated?

Price has come back and traded into it. Many traders treat a block as used once it has been touched, so a second visit is weaker. If price closes through the far side instead, the block has failed, and some traders then watch it as a breaker block.

Is an order block the same as a supply or demand zone?

They overlap. Both mark an area a strong move left from. An order block is narrower: one candle, or a short run of same-colour candles, picked by a rule. A supply or demand zone is usually drawn around the whole base the move started from.

Order blocks in the app

On Premium's extended analysis, StraviFX places the stop just beyond the swing high or low, or the order block, whose break would prove the idea wrong, plus a buffer of about half the average candle range over the last 14 candles (ATR). It doesn't place stops inside recent candle noise. The hourly Swing signals check doesn't look for order blocks; it works from sweeps, breaks of structure and fair value gaps. Either way, the levels are a reading of the chart, not a prediction, and the decision stays with you.
