Order block
An order block is a Smart Money Concepts idea: the last opposite candle before a strong impulse. It is a hypothesis about where big players were active, not a proven law.
How it works
A bullish order block is the last red (bearish) candle before a strong rally that breaks structure upward. A bearish one is the last green candle before a strong drop that breaks structure downward. The zone is drawn from that candle's high to its low (some traders use only the body).
The SMC (Smart Money Concepts) idea is that a large player built a position in that zone and some of their orders were left unfilled. When price returns, they may defend it again. Nobody has proven this explanation; in practice an order block works as a support or resistance zone found by specific rules.
Order blocks are seen as stronger when they led to a break of structure (BOS), left a fair value gap (FVG) and have not been retested yet. Traders usually look for an entry on the first return to the zone, with the stop beyond its far edge.
BTC was falling; the last red candle opened at 60,400 and closed at 60,200 with a low of 59,800, then price rallied hard to 63,000 and broke the last high. The 59,800 to 60,400 zone is a bullish order block. On a pullback to 60,400 a trader buys with a stop below 59,800 (about 600 dollars of risk per coin) and a target near 63,000 (about 2,600 dollars per coin), roughly 1:4 R:R. The zone may also fail to hold.
A common mistake is seeing an order block before every move and entering with no confirmation. Any chart has dozens of such candles and price simply runs through most of them. Pick only blocks that led to a real break of structure, check the higher timeframe, always put the stop beyond the zone and risk a small share of your account.
Questions and answers
What is an order block in simple terms?
It is a chart zone where, according to SMC, a large player built a position before a strong move. Traders expect price to bounce from it when it comes back.
How do I find an order block on a chart?
Find a strong impulse that broke the last high or low. The last opposite-colored candle before that impulse is the order block.
Is an order block the same as support and resistance?
It is similar, but the rules differ. A level is found by several touches, while an order block comes from one candle before an impulse and a structure break.
